Filed:

Jun 7, 2001

Appl. No.:

09/876619

Inventors:

Graham W. Bryan - Norwalk CT
Paul A. Matula - Brookfield CT

Assignee:

United States Surgical Corporation - Norwalk CT

International Classification:

A61B 1000

US Classification:

600566, 600567, 606167

Abstract:

An apparatus and method for the biopsy of tissue specimens and, more particularly, a single insertion multiple sample percutaneous biopsy apparatus and method are provided. A tip at a distal end of a vacuum support tube is introduced into a tissue mass. The vacuum support tube is retracted exposing a basket tube bounded by a front washer and a rear washer mounted thereabout forming a tissue basket. The basket tube is supported internally by a thrust tube which provides structure to the apparatus to allow it to penetrate tissue. The thrust tube and the basket tube are in fluid connection and are provided with suction to draw tissue inward. The tissue is then severed by rotating and advancing a knife edge at the distal end of the vacuum support tube. The tissue basket is withdrawn and the tissue sample is removed by rotating the vacuum support tube. The tissue sample is sliced longitudinally, and a stripper scrapes the tissue sample from an opening in the vacuum support tube.

US Classification:

606206, 606170, 606205, 600104, 600564

Abstract:

A surgical instrument is provided for use in endoscopic or laparoscopic procedures. The instrument includes a handle portion, an endoscopic portion extending from the handle portion, an articulating section pivotably connected to a distal end portion of the endoscopic portion, and a retractor assembly operatively associated with the articulating section. Structure is provided for manipulating the articulating section relative to the longitudinal axis of the endoscopic portion within an angular degree of rotation. An injection port may also be provided to deliver fluids through the endoscopic portion to the operative site.

International Classification:

A61B 17/14

US Classification:

606184, 606167

Abstract:

An aortic punch for creating an aortotomy in a wall of a luminal structure. The aortic punch includes a housing having distal and proximal ends, first and second plungers, a first return spring and a cutting assembly. The first plunger is movable relative to the housing to expose a barb from the distal end of the housing for piercing and catching the wall of the luminal structure. The first return spring biases the barb proximally toward the distal end of the housing such that the barb pulls the wall of the luminal structure into contact with the cutting assembly. The present disclosure also relates to a method of forming an aortotomy in a luminal structure.

Abstract:

Disclosed is multi-flow filter cartridge assembly that includes an elongated housing that has axially opposed proximal and distal ends and defines an interior cavity and first, second and third flow paths which extend from the proximal end of the housing to the distal end. The cartridge assembly also includes first, second and third filter elements. The first filter element is disposed within the interior cavity of the housing and conditions fluid that traverses the first flow path from a first inlet port to a first outlet port. The second filter element is disposed within the interior cavity of the housing and conditions fluid that traverses the second flow path from a second inlet port to a second outlet port. Lastly, the third filter element is also disposed within the interior cavity of the housing and conditions fluid that traverses the third flow path from a third inlet port to a third outlet port. The first flow path is isolated from the second and third flow paths and the second flow path is isolated from the third flow path.
