First Claim
1. An endoscopic suture punch, comprising:
- an elongate tubular frame;
a handle mounted to an end of said frame;
a pair of jaws mounted to the other end of said frame, wherein one jaw is movable, and one jaw is stationary, said movable jaw being pivotally mounted;
actuation means mounted to said frame for actuating at least one jaw wherein the actuation means comprises a lever pivotally mounted in the handle and an actuation rod pivotally connected to the lever on one end and to at least one jaw on the other end;
punch means mounted to at least one of said jaws for punching a pathway through tissue;
a suture pathway means through said handle, frame, jaws and punch means for receiving a suture;
wherein the suture pathway means comprises a first tubular member extending through the handle, frame, and a first jaw, a second tubular member extending through said first jaw and an arcuate pathway in the other jaw said arcuate pathway connecting the first and second tubular members; and

Abstract
An endoscopic suture punch for use in endosurgical procedures, especially an anti-reflux procedure. This suture punch has an elongate frame and a handle mounted to one end of the frame. A pair of opposed jaws having tissue punches is mounted to the other end of the frame. One jaw is rigidly mounted to the frame while the other jaw is movably mounted to the frame, although both jaws can be movably mounted. An actuation handle is mounted to the frame for actuating the jaws. The suture punch has a suture pathway through the frame, the punches and the jaws for receiving the suture. There is a suture drive mechanism mounted to the frame for moving the suture through the suture pathway. The endoscopic suture punch is used with an invaginator for performing an anti-reflux procedure. The endoscopic suture punch may typically be used for suturing and other endoscopic procedures.

19. A method of performing an anti-reflux procedure in a mammal, comprising:
-
A) inserting an invaginator into the esophagus of the mammal wherein the invaginator comprises; an elongate member having a distal end; tissue engaging means extendable from said member and attached to said member proximal to said distal end; and
,actuating means for actuating said tissue engaging means; actuating the actuating means to engage the distal end of the esophagus; B) displacing the invaginator and the tissue distally into the stomach to form an invaginated fold about the invaginator; C) inserting an endoscopic suture punch into the stomach proximal to the distal end of the invaginator, wherein the endoscopic suture punch comprises; an elongate tubular frame; a handle mounted to one end of frame; a pair of jaws mounted to the other end of said frame, wherein one jaw is movable and one jaw is stationary, said movable jaw being pivotably mounted; actuation means mounted to said frame for actuating at least one jaw wherein the actuation means comprises a lever pivotally mounted in the handle and an actuation rod pivotally connected to the lever on one end and to at least one jaw on the other end; punch means mounted to at least one jaw of punching a pathway through tissue; a suture pathway through said frame, handle, jaws and punch means for receiving a suture, wherein the suture pathway comprises a first tubular member extending through the handle, frame, and first jaw, a second tubular member extending through said first jaw and an arcuate pathway in the outer jaw said arcuate pathway connecting the first and second tubular members; and
,suture drive means mounted to said handle for moving a suture through the pathway means; D) suturing the invaginated fold by inserting the open jaws of punch about the invaginated fold; E) closing the jaws about the fold such that the punch means punch a pathway thorough the tissue of the fold; F) moving a suture through the suture punch pathway through the invaginated fold and out through the endoscopic suture punch by engaging the suture drive means; and
,G) securing a knot in the suture about the invaginated fold. - View Dependent Claims (20, 21, 23, 24, 25, 26, 27)
