Surgical instrument having a fastener delivery mechanism
First Claim
1. A delivery device for delivering a plurality of individual surgical fasteners, said delivery device comprising:
- a. a drive mechanism having distal and proximal ends, said drive mechanism comprising first and second opposing members, said members being moveable proximally and distally with respect to said delivery device, and individually with respect to each other;
b. at least one surgical fastener located between said first and said second members, each of said at least one surgical fasteners having a proximal end and a distal end;
c. an actuator having at least three sequential positions, a first position for moving said drive mechanism distally, and a second position for moving said first member proximally, thereby partially deploying said distal end of said fastener, and a third position for moving said second member proximally, thereby fully deploying said distal end of said fastener.

Abstract
A delivery device for delivering a plurality of individual surgical fasteners is disclosed. The delivery device has a drive mechanism having a distal and a proximal end, and a first and a second opposing member. The members are moveable proximally and distally with respect to the delivery device, and individually with respect to each other. The device further includes at least one surgical fastener located between the first and the second members. Each of the at least one surgical fasteners has a proximal end and a distal end. The surgical fasteners are preferably made from a superelastic nickel titanium alloy. Additionally an actuator having at least three sequential positions is included. The first position of the actuator is for moving the drive mechanism distally. The second position is for moving the first member proximally to partially deploy the distal end of the fastener. The third position of the actuator is for moving the second member proximally, to fully deploy the distal end of the fastener.

13. A delivery device for delivering a plurality of individual surgical fasteners, said delivery device comprising:
-
a. a drive mechanism having distal and proximal ends and a longitudinal axis therebetween, said drive mechanism comprising first and second opposing members, said members being moveable proximally and distally with respect to said delivery device, and individually with respect to each other;
b. a plurality of surgical fasteners disposed longitudinally within said drive mechanism between said first and said second members, each of said at least one surgical fasteners having a proximal end and a distal end;
c. an actuator for deploying one of said fasteners and moving said plurality said fasteners distally with respect to said longitudinal axis, said actuator causing said drive mechanism to move in at least three sequential positions, a first position moving said drive mechanism and said plurality of fasteners distally, and thereafter moving said first member proximally, thereby partially deploying said distal end of said fastener, and thereafter moving said second member proximally, thereby fully deploying said distal end of said fastener. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24)
