TECHNICAL FIELD OF THE INVENTION

The present invention relates generally to computer readable media for storing data relating to patients and tissue samples excised from their vascular or other lumens. The data may be used to analyze current, past, or future patient health, to assess treatments, to evaluate drugs, to evaluate risk factors, and to determine proposed treatments or assessments.

BACKGROUND OF THE INVENTION

Cardiovascular disease frequently arises from the accumulation of atheromatous material on the inner walls of vascular lumens, particularly arterial lumens of the coronary and other vasculature, resulting in a condition known as atherosclerosis. Atherosclerosis occurs naturally as a result of aging, but may also be aggravated by factors such as diet, hypertension, heredity, vascular injury, and the like. Atheromatous and other vascular deposits restrict blood flow and can cause ischemia which, in acute cases, can result in myocardial infarction. Atheromatous deposits can have widely varying properties, with some deposits being relatively soft and others being fibrous and/or calcified. In the latter case, the deposits are frequently referred to as plaque.

One conventional treatment for cardiovascular disease is the use of stents. Endoluminal stents are commonly used to treat obstructed or weakened body lumens, such as blood vessels and other vascular lumens. Once deployed in the blood vessel, the stent can remain in the body lumen where it will maintain the patency of the lumen and/or support the walls of the lumen which surround it. One factor impeding the success of stent technology in endoluminal treatments is the frequent occurrence of in-stent restenosis, characterized by proliferation and migration of smooth muscle cells within and/or adjacent to the implanted stent, causing reclosure or blockage of the body lumen.

Atherosclerosis and restenosis can be treated in a variety of ways, including drugs, bypass surgery, and a variety of catheter-based approaches which rely on intravascular debulking or removal of the atheromatous or other material occluding a blood vessel. Of particular interest to the present invention, a variety of methods for cutting or dislodging material and removing such material from the blood vessel have been proposed, generally being referred to as atherectomy procedures. Atherectomy catheters intended to excise material from the blood vessel lumen generally employ a rotatable and/or axially translatable cutting blade which can be advanced into or past the occlusive material in order to cut and separate such material from the blood vessel lumen.

There is a need in the art for methods and tools for managing and storing materials removed from body lumens. There is a need in the art for methods and tools for managing and storing information related to and/or derived from materials removed from body lumens.

BRIEF SUMMARY OF THE INVENTION

One aspect of the invention provides one or more computer readable media having a data structure stored thereon. The data structure comprises a first data field comprising a value corresponding to a property of a first tissue sample excised from a vascular lumen of a patient and a second data field comprising data identifying the patient. Optional additional data fields include a third data field comprising a value corresponding to cardiac health of the patient, a fourth data field comprising a value corresponding to a characteristic of the patient's blood, a fifth data field comprising a value corresponding to family history of the patient, a sixth data field comprising a value corresponding to the patient's medical history, a seventh data field comprising a value corresponding to a property of a second tissue sample excised from a vascular lumen of the patient at a distinct time, an eighth data field comprising a value corresponding to a property of a second tissue sample excised from distinct vascular lumen of the patient on the same day as the first tissue sample, a ninth data field which comprises a value which links a labeled storage container comprising excised tissue with a value in the second data field, a tenth data field which comprises a value which links the labeled storage containers comprising a component extracted or processed from an extracted tissue with a value in the second data field. These can be used separately or cumulatively. These data fields are not an exclusive list of possible useful data fields.

For a further understanding of the nature and advantages of the invention, reference should be made to the following description.

DETAILED DESCRIPTION OF THE INVENTION

Data collected related to samples of materials removed from body lumens can be stored in data structures. The stored data can be used to draw correlations, to stratify groups of patients, to provide risk assessments, to provide diagnoses and/or prognoses. Libraries of samples can be assembled to be used for studies of drugs, candidate drugs, toxins, therapeutic treatments, etc. The samples can be preserved according to any method known in the art. Samples may be frozen, for example, in liquid nitrogen. They may be preserved in paraffin, dried, freeze dried, etc. Samples may be treated to achieve a purified or semi-purified component of the sample. Samples may be treated, for example to extract DNA or protein. Samples may be treated to extract mRNA and to preserve it or “convert” it to cDNA. Desirably, samples are stored in a consistent and systematic way so that patient information remains associated with the samples so that patient outcome or other data collected at a later time can be associated with the sample concurrently or at a later time.

Samples within a library can be stored and associated with information related to the sample itself, e.g., its properties, and the patient from whom the sample was excised. Other information that can be associated with the sample include results of analyses of the sample, patient history information, patient outcome information, drug efficacy information, therapeutic efficacy information, family history, factors of the patient related to cardiac disease, factors of the patient related to non-cardiac disease. In some cases this information may be stored without association with the physical samples. Patient identifying information may be coded so that confidentiality can be maintained while still permitting correlation of various patient attributes with the samples.

One or more aspects of the invention may be embodied in computer-usable data and computer-executable instructions, such as in one or more program modules, executed by one or more computers or other devices. Generally, program modules include routines, programs, objects, components, data structures, etc. that perform particular tasks or implement particular abstract data types when executed by a processor in a computer or other device. The computer executable instructions may be stored on a computer readable medium such as a hard disk, optical disk, removable storage media, solid state memory, RAM, etc. As will be appreciated by one of skill in the art, the functionality of the program modules may be combined or distributed as desired in various catheters. In addition, the functionality may be embodied in whole or in part in firmware or hardware equivalents such as integrated circuits, field programmable gate arrays (FPGA), and the like. Particular data structures may be used to more effectively implement one or more aspects of the invention, and such data structures are contemplated within the scope of computer executable instructions and computer-usable data described herein.

Data fields which are present in the data structures of the present invention may include one or more of those discussed below. A first data field comprises a value corresponding to a property of a first tissue sample excised from a vascular lumen of a patient. The tissue sample is typically material that has been excised from a body lumen. The body lumen is often a vascular lumen. The property may be, for example, level of a marker in the tissue, composition of the tissue sample, histologic characterization, immunochemical characterization of the tissue, a genomic characteristic of the tissue, level of a mRNA in the tissue, location of the vascular lumen from which the tissue was excised, or volume or mass of the excised tissue. Any property of the tissue may be stored in this data field. A second data field may comprise data identifying a patient. The patient data may be anonymous or identify a person. If anonymous, the code will uniquely identify a patient's characteristics, without actually identifying the patient. Thus data can be used for studies, without divulging identities of the patients.

An optional third data field comprises a value corresponding to cardiac health of the patient. Such values may, for example, relate to past infarct history, past angioplasty procedures, or past cholesterol values. A possible fourth data field comprises a value corresponding to a characteristic of the patient's blood. The blood may have been withdrawn at the time of or before tissue excision. The blood characteristic may be any known in the art, including but not limited to, sedimentation rate, red blood cell count, white blood cell count, triglycerides, and C-reactive protein.

An optional fifth data field comprises a value corresponding to family history of the patient. Thus a value can be assigned to family history events based on degree of relatedness of the family member and the severity of the event. An optional sixth data field comprises a value corresponding to the patient's own medical history. This history includes but is not limited to cardiac related events. Thus other medical history events can be recorded which may not be currently known to be associated with vascular occlusion, but which may in fact have a correlation. Such data will make the data structure useful for discovering new associations, risks, and mechanisms. Such data may also be useful in stratifying patients for treatment regimens and for drug trials.

An optional seventh data field comprises a value corresponding to a property of a second tissue sample excised from a vascular lumen of the patient at a distinct time from the first tissue sample. The second tissue sample can be excised from the same vascular lumen as the first tissue sample or from a different vascular lumen of the patient. An optional eighth data field comprises a value corresponding to a property of a second tissue sample excised from a distinct vascular lumen of the patient on the same day as the first tissue sample.

The computer readable media can optionally be associated with one or more excised tissue samples in labeled storage containers. Labeled storage containers includes storage containers that are in fixed positions or parts of a machine or apparatus which positions are themselves labeled. If such stored tissue samples are associated with the data structure, an optional ninth data field can be used which comprises a value which links the labeled storage containers with a value in the second data field. Alternatively, the labeled storage containers may be labeled with a value in the second data field. Alternatively or optionally the data structure can be associated with labeled storage containers in which one or more samples comprise a component extracted or processed from an excised vascular tissue from a vascular lumen of the patient. Such components include DNA, RNA, cDNA, lipid, carbohydrate, and protein. In such a case, the data structure can optionally comprise a tenth data field in which a value which links the labeled storage containers with a value in the second data field is present. Alternatively, such labeled storage containers can be labeled with a value in the second data field. There is no significance to the numbers of the data fields as used herein. Data fields with sequential numbers need not be used. Thus, for example, a structure can comprise data fields with fields 1, 2, 5, and 6 without data fields 3, 4, 7, 8, 9, and 10.

Catheters can be used to debulk atheroma and other occlusive material from diseased body lumens, and in particular coronary arteries, de novo lesions, and in-stent restenosis lesions. Catheters are also suitable for treating stenoses of body lumens and other hyperplastic and neoplastic conditions in other body lumens, such as the ureter, the biliary duct, respiratory passages, the pancreatic duct, the lymphatic duct, and the like. Neoplastic cell growth will often occur as a result of a tumor surrounding and intruding into a body lumen. Debulking of such material can thus be beneficial to maintain patency of the body lumen. The debulked material is typically a continuous strip of tissue removed from the lumen interior wall that ranges from about 1 mg to about 2000 mg; it retains the structure of the tissue prior to removal. The continuous strip or strand of tissue removed will typically have a length that is longer than a length of the cutting window. The data storage and access structures of the present invention can be applied to a variety of occlusive, stenotic, or hyperplastic material in a variety of body lumens.

Apparati will generally comprise catheters having catheter bodies adapted for intraluminal introduction to the target body lumen. The dimensions and other physical characteristics of the catheter bodies will vary significantly depending on the body lumen which is to be accessed. In the exemplary case of atherectomy catheters intended for intravascular introduction, the proximal portions of the catheter bodies will typically be very flexible and suitable for introduction over a guidewire to a target site within the vasculature.

Generally, the smooth muscle cells of the stenotic material show a range of phenotypes, but most of the cells contained myofilaments as well as a relatively high amount of synthetic organelles, such as rough endoplasmic reticulum, Golgi apparatus and mitochondria. One can determine how much stenotic tissue is retrieved in an access procedure. One can determine presence or absence of inflammatory cells in excised tissue. One can determine the presence of inflammatory cells within critical areas of plaque. Determination of the location and degree of inflammatory cells present may facilitate a more informed characterization or diagnosis.

The material removed from a catheter collection chamber, or a portion thereof, can be placed in a preserving agent, a tissue fixative, and or a preparation agent suitable for a desired test prior to testing the material. The material removed from the patient by this method is typically at least one or more continuous strip(s) of material that maintains the structure of the material in vivo. The quantity of material removed by the method can be from about 1 mg to about 2000 mg. Typically the amount of material is about 1 mg to about 100 mg, about 100 mg to about 200 mg, about 200 mg to about 300 mg, 300 mg to about 400 mg, 400 mg to about 500 mg, 500 mg to about 600 mg, about 600 mg to about 700 mg, 700 mg to about 800 mg, or about 800 mg to about 2000 mg. In a typical procedure about 400 mg to about 600 mg of material is removed and available for testing and/or storage. Collection of one or more continuous strips of material from the inner surface of a lumen may be longer than a largest dimension of the cutting window of a catheter used to remove the material. In a particular example, the material can comprise plaque tissue. The material can be collected from a single site or at least one additional site in the same or a different body lumen.

Excised material can be stored to permit later confirmatory or additional testing without having to subject the patient to another percutaneous translumenal lumenectomy procedure. The material can be tested by genomic screening, DNA hybridization, RNA hybridization, gene expression analysis, PCR amplification, proteomic testing, drug efficacy screening, presence of one or more protein markers, presence of one or more DNA markers, presence of one or more RNA markers, histological testing, histopathology, cytopathology, cell and tissue type analysis, biopsy, and the like. Additionally, the material can also be cultured and/or tested to determine sensitivity to drugs, toxins, and the like. The material can be tested for the presence of DNA, RNA, or protein markers comprising a smooth muscle proliferative promoter, a smooth muscle proliferative inhibitor, a cellular marker, an apoptotic marker, a cell cycle protein, a transcriptional factor, a proliferative marker, an endothelial growth factor, an adhesion molecule, a cytokine, a chemokine, a chemokine receptor, an inflammation marker, a coagulation factor, a fibrinolytic factor, an oxidative stress related molecule, an extracellular matrix molecule, an interleukin, a growth factor, a glycoprotein, a proteoglycan, a cell-surface marker, a serum marker, and or an immune factor, and the like. Tests for each of these molecules and others are well known to the skilled artisan as are methods and preservatives, fixatives and preparation agents for adding to all or a portion of the material collected. The results of any of the tests for properties of the removed material can be stored in a data structure according to the invention.

The material produced by a lumenectomy comprises at least one continuous tissue stand collected in vivo from an inner surface of the body lumen of a subject. The body lumen can be an artery or other lumen or vessel of the circulatory system and the material can comprise arterial plaque and associated tissue. The continuous strand of tissue provided by the disclosed methods provide a sufficient amount of high quality material to successfully perform at least one or more tests comprising, for example, genomic screening, DNA hybridization, RNA hybridization, gene expression analysis (including serial analysis of gene expression), PCR amplification, proteomic testing, drug efficacy screening, a determination of the presence of one or more protein markers, a determination of the presence of one or more DNA markers, a determination of the presence of one or more RNA markers, histological testing, histopathology, cytopathology, cell type analysis, tissue type analysis, biopsy, and the like. Methods for performing each of the tests are well known to the skilled artisan. It is also well known that material collected from a patient can be added to a preserving agent, tissue fixative, or a preparation agent in order to prepare at least a portion of collected material for the desired test. Agents known in the art for preserving, fixing or preparing the material for later use include, for example, saline, heparinized saline, liquid nitrogen, formalin, a membrane lysis agent, a RNA or DNA preparation agent, and the like. Particular tests that can be carried out successfully on the excised lumenectomy material include, but are not limited to, histology techniques including hematoxylin and eosin staining, connective tissue staining, carbohydrate staining, and lipid staining, and the like. In addition, tissue array testing, enzyme histochemistry, transmission electron microscopy, immunohistology, immunocytochemistry, immunoassays, immunofluorescent assays, immunoprecipitation assays, ELISA, flow cytometry, fluorescent activated cell sorting, radioimmunochemistry, electrophoresis, two-dimensional gel electrophoresis, Western blotting, protein sequencing, mass spectrometry, proteomic analysis, and protein microarray analysis can be carried out. Further, cytogenetic testing, Nothern blotting, RNase protection assays, in situ hybridization assays, DNA microarray testing, reverse transcription polymerase chain reaction PCR (RT-PCR), Southern blotting, DNA sequencing, PCR amplification, single strand conformational polymorphism assays, single strand polymorphism (SNP) assays, and serial analysis of gene expression (SAGE) assays can be successfully carried out with the lumenectomy materials compositions. The compositions can also be prepared for storage for later testing.

Table 1 shows relevant markers for which the excised vascular material can be tested for expression, and about which data can be stored.
