In some cases, the vapor may have a predetermined aerosol number density and/or a predetermined average aerosol diameter. The vaporization device may generate a vapor from a vaporizable material. In some cases, the vaporizable material may be a liquid material housed in a cartridge. The vaporization device may comprise a rechargeable power storage device.

Abstract: Ablation and visualization systems and methods to access quality of contact between a catheter and tissue are provided. In some embodiments, a method for monitoring tissue ablation of the present disclosure comprises advancing a distal tip of an ablation catheter to a tissue in need of ablation; illuminating the tissue with UV light to excite NADH in the tissue, wherein the tissue is illuminated in a radial direction, an axial direction, or both; determining from a level of NADH fluorescence in the illuminated tissue when the distal tip of the catheter is in contact with the tissue; and delivering ablation energy to the tissue to form a lesion in the tissue.

Abstract: A medical device is provided for irrigation of a patient wound site. The device contains a tube having a proximal portion adapted to receive an irrigation solution, a distal portion having a nozzle and an intermediate portion for transporting the solution. The tube has a barrel portion that may be manipulated by a user to position the device relative to the wound site. A distinctive nozzle has a body formed with a distally leading channel presenting a semispherical first spatial conformation and a proximally leading opening formed in the body presenting a second spatial conformation intersecting the semispherical terminus. This geometry, derived from principles of flow mechanics discussed herein, defines what will be described as an “effective diameter” of the nozzle. An assembly and system utilizing the device am also disclosed. The invention utilizes a fluid-isolating durable peristaltic pump for a continuous flow of irrigation solution, along with a single use tube set that embodies the device.

Abstract: Compositions and methods for pharmacodynamic monitoring of immunotherapy are provided herein. The compositions include an immunotherapeutic agent linked to protease substrates. Upon administration, the compositions target to sites of disease where proteases are upregulated during responsive immunotherapy and subsequently cleave the attached substrates. Cleavage fragments are detected in a sample from the body and detection of the fragments is indicative of an effect of the immunotherapeutic agent.

Abstract: A system and method for self-calibrating optical turbidity measurements includes a housing comprising a cavity with an inner wall having an essentially straight section and an opening for the medium. An optical standard is moveable between first and second sections within the essentially straight section, and a light source and a light sensor, arranged at the first section and configured to measure the turbidity of the medium, when the optical standard is at the second section, and configured to measure the turbidity of the optical standard and to determine, as a function of the measured turbidity, a calibration coefficient for performing a self-calibration, when the optical standard is at the first section.

Abstract: The procedure and surgical information alert system 10 is a surgical management system for capturing, storing, processing, tracking, and sharing patient and procedural identification data, including implant data, during medical/surgical procedures performed at multiple medical offices 20 and/or surgical center 30 locations. The procedure and surgical information alert system 10 allows for accurate verification of the predetermined procedure verified between the physician and patient during the scheduling process at a medical office 20, which is confirmed at that time by the patient's signature. On the day of the surgical procedure, the patient information is re-verified by the patient at a surgery center. Prior to the surgical procedure, a time-out alert warning 240 is generated to freeze use of the system until physician verification of the patient information is confirmed. Implant inventory alert warnings 192 are provided to authorized surgery center staff based on predictive implant inventory needs.

Abstract: An activity sensor sensitive to enzymes indicative of the presence of cancer is used to provide non-invasive reporting of tumor development and response to anticancer therapies useful in determining suitability and effectiveness of various treatments including immuno-oncological therapies. Localized reporters are used in patient stratification in clinical trials, monitoring of drug response or disease progression, and differentiating between anti-tumor immune response, tumor progression, and off-target immune response. Activity sensors may include tuning domains to modulate tissue localization and residency. Periodic measurements of activity sensor reporters may be analyzed to determine a velocity value indicative of disease prognosis.

Abstract: An activity sensor sensitive to enzymes indicative of tissue condition are co-administered with control or normalizing activity sensors providing levels of the same enzyme in other tissues or levels of control enzymes indicative of assay success. Levels of control reporters can be used to normalize activity sensor data across samples such as in analyte velocity analyses. Control reporters can also be used to differentiate localized enzyme activity from systemic activity and to confirm activity sensor localization or to troubleshoot activity sensor uptake problems. Activity sensors and controls sensitive to immunological enzymes are particularly useful in assessing immuno-oncology treatments.

Abstract: Data from activity sensors sensitive to enzymes indicative of various disease states is combined with data from other sources including electronic medical records and clinical data including molecular diagnostic testing. The pooled data can be analyzed to identify patterns indicative of certain outcomes including development of a disease, progression of a disease, or likely therapeutic efficacy of a given treatment for a patient.
