Abstract: A surgical biopsy apparatus is provided which includes a housing; a first elongated tubular member removably mounted in the housing and defining a fluid passageway therein, the first elongated tubular member including: a tapered closed distal end portion adapted to penetrate tissue; a laterally disposed tissue receiving opening formed near the tapered distal end which includes a tissue support surface defining a plurality of holes in fluid communication with the fluid passageway; and a second elongated tubular member rotatably and reciprocatingly disposed coaxially about the first elongated tubular member, the second elongated tubular member having a cutting edge formed at an open distal end thereof and a lateral tissue discharge port formed proximally of the cutting edge.

Abstract: A surgical clip applying instrument is disclosed which includes a handle portion, a body extending distally from the handle portion and defining a longitudinal axis, and a plurality of surgical clips disposed within the body. A jaw assembly is mounted adjacent a distal end portion of the body. The jaw assembly includes first and second jaw portions movable between a spaced-apart and an approximated position. A clip pusher is provided to individually distally advance a distalmost surgical clip to the jaw assembly while the jaw portions are in the spaced-apart position. An actuator at least partially disposed within the body is longitudinally movable in response to actuation of the handle portion. A jaw closure member is positioned adjacent the first and second jaw portions to move the jaw portions to the approximated position.

Abstract: A piercing tip for penetrating body tissue is provided which includes a conical body and a triangular cutting blade positioned within a slot formed in the conical body. The cutting blade includes a proximal mounting flange which extends outwardly from the conical body and is configured for mounting at the distal end of an obturator of a trocar assembly.
