摘要： Instruments for performing percutaneous biopsy procedures are disclosed, which have advantageous features for improving functionality and performance over prior art devices. These instruments comprise two types, single-use devices, and multiple-use devices having active tissue capture capability. Improved features include the ability to retrieve and evaluate multiple tissue samples during a single insertion procedure, without physical handling of the samples, as well as constructional features, such as a molded tissue cassette housing, variant vacuum port embodiments suited for different tissue environments, and a method for backflushing the instrument to remove biological debris, among others.

摘要： A device and method of using the device to access a desired tissue site within a patient's body and separating a tissue specimen from the tissue site suitable for evaluation. The device includes a probe member having an arcuate tissue-cutting RF powered electrode secured to and distally spaced from the distal end of the probe and a small dimensioned distal extremity which when an inner lumen thereof is subjected to a vacuum, secured tissue for the specimen to the surface of the distal extremity. A circular tissue-cutting blade preferably secured to the distal end of a supporting tube is configured to rotate and move longitudinally along the shaft of the probe member effective to sever a tissue specimen from tissue secured to the surface of the distal extremity of the probe member. The supporting tube covers the separated specimen, and may be disposed within an accessing cannula.

摘要： The invention provides systems, methods and a node accessing and anchoring device, comprising an elongated shaft, a tissue cutting member, at least one anchoring element extending from a position at or near the distal end of the shaft; and a radiation detector. The radiation detector is effective to locate and identify sentinel lymph nodes following injection of radioactive material into a primary lesion site within a patient. The tissue cutting member, which may be activated with radio frequency energy, is effective to allow access of the elongated shaft to a sentinel lymph node. The anchoring elements are effective to anchor the device to or adjacent a sentinel lymph node accessed by the device. Anchoring elements may assume radially, longitudinally, or mixed radially and longitudinally curved or coiled configurations when deployed.
