Abstract

A method and apparatus for closing a punctured blood vessel is described. The method includes providing a suturing instrument adapted to apply at least one suture to at least a portion of a blood vessel in order to close a puncture wound therein. In a preferred embodiment, the suture is secured by crimping a sleeve member over the free ends of the suture.

Claims

1. A surgical apparatus comprising:

a) a body portion having first and second levers pivotally secured thereto;

b) an elongate body assembly having a longitudinal axis and extending from said body portion;

c) a tongue member extending from a distal end of the elongate body assembly, the tongue member having a distal opening;

d) a ferrule holder secured to said tongue member;

e) first and second ferrules disposed within the ferrule holder, said first and second ferrules being joined by a length of suture material;

f) first and second elongate needles positioned at least partially within the elongate body assembly, said first needle being longitudinally movable by said first lever and said second needle being longitudinally movable by said second lever, wherein said first and second levers are pivotable independent of one another to independently move said first and second needles into engagement with said first and second ferrules, respectively;

g) a guide wire tube disposed through said body portion and said elongate body assembly, a distal end of the guide wire tube being disposed adjacent the distal opening of said tongue member; and

h) an opening in said guide wire tube spaced proximal of the distal end thereof.
