Vascular puncture stapling system
First Claim
1. A stapling system for closing a vascular puncture comprising:
- a tissue staple having proximal and distal ends with a crown at the proximal end and a plurality of prongs extending distally from the crown, the staple having a central axis and the prongs being disposed about the central axis, wherein each prong includes a tab extending towards the central axis;
a mandrel adapted to slidably receive the staple along an outer surface of the mandrel, the mandrel including,a proximal groove corresponding to each prong, the proximal groove adapted to receive the tab of the corresponding prong,a ramp disposed within each proximal groove,a distal groove disposed distal of the ramp, wherein the distal groove is adapted to receive the tabs of the prongs, anda distal anvil disposed distally of the distal groove, wherein the distal groove and the distal anvil form an abrupt angle; and
a pusher adapted to slidably receive the mandrel within a lumen of the pusher, wherein the pusher is disposed proximally of the staple and a distal end of the pusher is abuts the crown of the staple.

Abstract
A stapling system includes a tissue staple, a mandrel, and a pusher. The staple includes a crown at the proximal end and a plurality of prongs extending distally therefrom about a central axis of the staple. Each prong of the staple includes a tab extending towards the central axis. The mandrel receives the staple along an outer surface thereof. The mandrel includes a proximal groove adapted to receive the tab of the corresponding prong. The proximal groove includes a ramp from a proximal portion of the proximal groove to a distal portion of the proximal groove. The mandrel further includes a distal groove adapted to receive the tabs of the prongs and a distal anvil disposed distally of the distal groove. The pusher is disposed around the mandrel abutting and proximal to crown of the staple.
