    摘要： The invention is directed to tissue cutting members and biopsy devices with such tissue cutting member for separating a tissue specimen from a patient's body at a target site. The tissue cutting member is slidably disposed within an inner lumen of an elongated probe member of the biopsy device to cut a tissue specimen drawn into the interior of an outer cannula of the biopsy device through a tissue receiving aperture in the probe. The tissue cutting member has a tubular distal portion with a distal tip having an outer tissue cutting edge, an inner tissue receiving aperture, and a longitudinally oriented opening with a closed proximal end and open distal end which opens to the inner tissue receiving aperture to facilitate flaring of the distal tubular portion. The cutting member has at least one opening in a wall of the tubular portion to maintain a vacuum during use.

    摘要： The invention is directed to a system and method for separating and collecting one or more tissue specimens from a target site within a patient and flushing the specimen to remove blood, debris and the like before the specimen is removed from the biopsy device. The flow of flushing fluid to the tissue collector is preferably controlled to coincide with delivery of one or more specimens to the collecting tray or basket of the device or after the receipt of the specimen within the tissue collector to ensure that the fluid is applied to a fresh specimen. The tissue tray or basket within the tissue collector has an open or foraminous portion to facilitate removal of fluid, such as the applied fluid and blood, and other debris from the tissue specimens on the tray. Vacuum is provided within the tissue collector, preferably under the tray to remove fluid and debris from the collector interior.

    摘要： The invention is directed biopsy site markers and methods of marking a biopsy site, so that the location of the biopsy cavity is readily visible by conventional imaging methods, particularly by ultrasonic imaging. The biopsy site markers of the invention have high ultrasound reflectivity, presenting a substantial acoustic signature from a small marker, so as to avoid obscuring diagnostic tissue features in subsequent imaging studies, and can be readily distinguished from biological features. The several disclosed embodiments of the biopsy site marker of the invention have a high contrast of acoustic impedance as placed in a tissue site, so as to efficiently reflect and scatter ultrasonic energy, and preferably include gas-filled internal pores. The markers may have a non-uniform surface contour to enhance the acoustic signature. The markers have a characteristic form which is recognizably artificial during medical imaging. The biopsy site marker may be accurately fixed to the biopsy site so as to resist migration from the biopsy cavity when a placement instrument is withdrawn, and when the marked tissue is subsequently moved or manipulated.

    摘要： The invention is directed to a system and device for separating and collecting a tissue specimen from a target site within a patient. The device includes a probe component with an elongated tubular section, a penetrating distal tip and a tissue receiving aperture in the distal end of the tubular section proximal to the distal tip, and a tissue cutting member which is slidably disposed within the probe member to cut a tissue specimen drawn into the interior of the device through the aperture by applying a vacuum to the inner lumen of the tissue cutting member. The device also has a driver component to which the probe component is releasably secured. The driver has a drive member for adjusting the orientation of the tubular section and thus the aperture therein and one or more drive members for moving the tissue cutting member within the tubular section to sever a tissue specimen from tissue extending into the interior of the tubular section through the aperture. The motion imparted to the tissue cutter is at least longitudinal and preferably is also oscillation and/or rotational to effectively separate a tissue specimen from tissue extending through the aperture in the tubular section.
