  • Publication number: 20200138541
    Abstract: The present disclosure includes customized guidance devices in the form of guidance templates configured to fit over a given area of a patient's body and provide guidance during a tissue treatment or tissue removal procedure of that given area, which may include administration of an agent to a target tissue, target tissue biopsy, target tissue resection, or target tissue ablation. The customized guidance templates are generally constructed via an additive manufacturing process (i.e., three-dimensional (3D) printing) or subtractive manufacturing process (i.e., milling) based on a fabrication instruction file, which may include imaging data of the given area of the patient's body in which targeted tissue treatment is to be performed. The fabrication instruction file may further include additional data, such as the type of procedure to be performed (i.e., biopsy of the tissue abnormality, destruction or resection of the tissue abnormality, etc.).

  • Publication number: 20190350491
    Abstract: The present disclosure includes support devices configured to be prevent breast deformation during an MRI imaging procedure. One embodiment of a support device comprises a foam insert shaped and sized to rest between a patient's breasts, generally upon the patient's sternum. The support device has a surface configured to engage an imaging modality component (i.e., coil of MRI machine) and prevent and/or minimize contact between the portion of the MRI coil and the pair of breasts when the support device is placed on the surface of the patient, which, in turn, reduces or eliminates any deformation of the breasts upon application of force from the MRI coil in a direction towards the breasts during an MRI imaging procedure.

  • Patent number: 10467748
    Abstract: Quantitative analysis of a tissue sample includes carrying out a ploidy measurement on a plurality of nuclei of the sample to determine the ploidy type of a sample and also carrying out a stroma measurement on a section to determine the stroma type of a sample. The ploidy type, e.g. diploid or non-diploid, and the stroma type, high or low stroma, give an improved patient survival estimate than the ploidy type alone.

  • Publication number: 20080108950
    Abstract: Described is a method and a device for inserting a helical member into a living body. The device may include a handle having an actuator lever rotatably coupled thereto. The device may also include a helical member which has a tissue piercing distal tip. The helical member is coupled to the handle via a linkage operating so that, as the actuator lever is rotated in a first direction relative to the handle, the helical member is rotated and moved distally to screw into tissue along a substantially helical path.

  • Publication number: 20050015049
    Abstract: A device for preventing closure of a surgically created resection cavity within tissues of the body comprises an insertion member having a distal end for insertion into a surgically created resection cavity and a proximal end which remains outside the resection cavity and a lumen extending between the proximal and distal ends and an inflatable member deployable from the distal end of the insertion member, an inner chamber of the inflatable member being fluidly coupled to the lumen to receive an inflation fluid therefrom so that, when the inflation fluid is supplied to the inflatable member, the inflatable member expands so that an outer surface of the inflatable member contacts the surrounding tissue and moves the surrounding tissue out of the resection cavity.
