摘要： A biopsy device includes an elongated probe having a central longitudinal axis, a proximal end, and a distal end. A tissue penetrating tip includes a proximal base and a sharp distal point. The proximal base is secured to the distal end of the elongated probe. The sharp distal point is distal to the proximal base and is aligned with the central longitudinal axis. The tissue penetrating tip has a plurality of concave surfaces annularly arranged to form at least three adjacent pairs of concave surfaces. Each concave surface of the plurality of concave surfaces extends from the proximal base to the sharp distal point. Each adjacent pair of concave surfaces intersect to form a concave curved cutting edge. Cumulatively, the at least three adjacent pairs of concave surfaces form a plurality of concave curved cutting edges that distally terminate at the sharp distal point.

摘要： A biopsy device includes an elongated probe having a central longitudinal axis, a proximal end, a distal end, and an aperture. A tissue penetrating tip includes a proximal base secured to the distal end of the probe. A sharp distal point distal to the proximal base lies on the central longitudinal axis. Each of a first, second and third concave surface is configured to extend from the base to the sharp distal point. The second concave surface is located to intersect the first concave surface to form a first curved cutting edge. A third concave surface is located to intersect the first concave surface to form a second curved cutting edge and is located to intersect the second concave surface to form a third curved cutting edge. Each curved cutting edge extends from the base to the sharp distal point. A tissue cutting device is coaxial with the probe.

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 to devices and methods for separating and collecting a tissue specimen from a patient's target site. The device includes a probe member with a penetrating distal tip and a tissue receiving aperture, and a tissue cutting member which is rotatable disposed within the probe member to cut a tissue specimen drawn into the interior of the device through the aperture. The longitudinal edges of the aperture are preferably sharpened to engage the cutting edges of the tissue cutting member. Vacuum may be provided in the inner lumen of the cutting member to transport tissue therethrough. Rotation, rotational oscillation and/or longitudinal reciprocation of the tissue cutting member is effective to separate a tissue specimen from surrounding tissue. An accessing cannula having an tissue receiving aperture may be concentrically disposed within the probe member and about the tissue cutting member. The tissue cutting edge of the tissue cutting member preferably is longitudinally oriented and may have a cutting angle less than 90° with respect to the longitudinal axis of the tissue cutting member.

摘要： A biopsy device includes a tissue cutting member slidably disposed within a probe component. The tissue cutting member has a distal tubular portion having a longitudinal axis and a flared distal section. The flared distal section has an inclined distal tip and an outwardly flared distal tubular portion that defines an inner tissue receiving aperture. The inclined distal tip has a beveled front face with a leading tissue cutting edge and a trailing cutting edge. A longitudinally oriented opening is in the flared distal section. The longitudinally oriented opening has an open distal end and is configured to extend from a closed proximal end to the open distal end. The closed proximal end has a relief opening with a transverse dimension larger than a transverse dimension of the longitudinally oriented opening adjacent the relief opening. The longitudinally oriented opening diverges to intersect the trailing cutting edge.

摘要： A screen providing a GUI is disclosed for a tissue biopsy system having a tissue cutting member. The screen includes a first GUI area configured to represent a first region of the target site from which at least one tissue specimen has been separated from tissue at the target site by the tissue cutting member. The screen further includes a second GUI area configured to represent a second region from which the tissue cutting member may separate one or more additional tissue specimens from tissue at the target site. The screen includes a third GUI area configured to represent a third region in which the tissue cutting member is deployed to separate a tissue specimen from tissue at the target site. The GUI is configured to update the first GUI area, the second GUI area, and the third GUI area as the tissue cutting member is rotated within the patient.
