Abstract

A closure device for an arteriotomy includes an elongate tube having a distal opening. The elongate tube has least two opposing longitudinal slots and a pair of opposing corners defined where each slot meets the distal opening. A staple is disposed within the tube, the staple having at least two opposing legs aligned with the at least two slots. Each slot is pinched together adjacent the distal opening such that the opposing corners of each slot converge to cover the tip of the respective staple leg to guard the staple tips against contact with the tissue track. The corners of each slot are separable to permit the respective staple leg to pass there between.

Claims

1. A closure device for an arteriotomy comprising;

an elongate tube having a distal opening and at least two opposing longitudinal slots extending proximally there from and a pair of opposing corners defined where each slot meets the distal opening of the tube; and

a staple being slidably disposed within the tube and having at least two opposing legs aligned with the at least two slots, each staple, leg having a tip;

wherein each slot is pinched together adjacent the distal opening such that the opposing corners of each slot converge to cover at least the tip of the respective staple leg.

2. The closure device of claim 1 wherein, the opposing corners of each slot are separable to permit the respective staple leg to pass there between.

3. The closure device of claim 1 wherein the elongate tube includes at least two side tubes for riding along a pair of stabilization wire guides, the side tribes being coupled parallel to, and disposed on opposing sides of a distal portion the elongate tube.

4. The closure device of claim 1 further comprising an elongate stapler slidably disposed within the elongate tube, the stapler comprising;

an elongate hollow shaft and an elongate driver slidably disposed therein;

a pair of opposing actuation tips disposed at a distal end of the shaft and defining an open-sided staple chamber there between, the open sides of the chamber being aligned with the at least two slots in the elongate tube; and

an anvil fixedly disposed within the staple chamber;

wherein at least a proximal portion of the staple is held within the staple chamber.

5. The closure device of claim 1 further comprising an elongate stapler slidably disposed within the elongate tube and holding at least a proximal portion of the staple.

6. The closure device of claim 5 wherein the stapler comprises:

an elongate hollow shaft and an elongate driver slidably disposed therein;

a pair of opposing actuation tips disposed at a distal end of the shaft and defining a staple chamber there between; and

an anvil disposed within the staple chamber and affixed to one of the actuation tips;

wherein at least a proximal portion of the staple is held within the staple chamber.
