Abstract: Devices and methods for cutting and collecting a specimen from a mass of tissue. The device may include an integrated cut and collect assembly. The integrated cut and collect assembly includes a cutting portion and a collection portion that includes a flexible membrane. The collection portion of the assembly is attached to the cutting portion thereof. The cutting portion is configured to cut the specimen from the mass of tissue and the collection portion is configured to collect the cut specimen and to encapsulate and isolate the cut specimen within the membrane to enable its safe retraction from the mass of tissue.

Abstract: A needle is used to mark a tissue area of interest. The needle may have one or more indicators which indicate selected angular orientations relative to the needle. The indicators may also be coupled to anchors which are deployed in the tissue to anchor the needle in the tissue. The needle may be positioned to guide an excisional device to remove tissue.

Abstract: The device is used to remove tissue from a patient and to also place a marker in the patient. The device has an opening through which tissue enters the device. The tissue which enters the opening is cut and the tissue is removed. The device may be used a number of times to remove a number of tissue masses. The device also includes a marker which the user may release in the patient at the desired time.

Abstract: An excisional biopsy device includes a tubular member having a window near a distal tip thereof; a cutting tool, a distal end of the cutting tool being attached near the distal tip of the tubular member, at least a distal portion of the cutting tool being configured to selectively bow out of the window and to retract within the window; and a tissue collection device externally attached at least to the tubular member, the tissue collection device collecting tissue excised by the cutting tool as the biopsy device is rotated and the cutting tool is bowed.
Abstract: An implant for filling a cavity created by an excisional procedure includes first and second portions. The first portion may include a first collagenous matrix that defines a first selected crosslinking density and the second portion may include a second collagenous matrix that defines a second selected cross-linking density that is different than the first cross-linking density. The first and second cross-linking densities may be selected so as to cause the first and second portions to swell in such a manner that the implant swells into a size and a shape that is similar to the predetermined size and shape of the cavity when the implant is implanted. An aqueous solution may be added to the cavity if the cavity is not sufficiently aqueous to cause the implant to swell.

Abstract: The present invention is directed to tissue removal devices and methods. A tubular element having an open distal end is advanced into tissue so that tissue enters the tubular element. The tissue, which entered the tubular element is cut to separate the tissue from the surrounding tissue. The tissue is then transported proximally by the cutting element or a separate transport element.
