First Claim
1. An apparatus for delivering a closure element to an opening formed in a wall of a body lumen or body tissue, comprising:
- a backing member having a distal end region configured to extend into said opening and to selectably engage said wall of said body lumen or said body tissue adjacent to said opening;
a carrier assembly coupled with said backing member, said carrier assembly comprising a carrier member retaining said closure element in a substantially tubular configuration within said carrier assembly, and a pusher member adapted to deploy said closure element; and
an energy storing member associated with said carrier assembly, said energy storing member adapted to cause relative motion between said carrier member and said pusher member;
wherein said closure element is configured to engage at least a portion of said wall of said body lumen or said body tissue whereby said opening is drawn substantially closed.

Abstract
An apparatus for delivering a closure element into an opening formed in a blood vessel or other body lumen and methods for manufacturing and using same. The apparatus is configured to retain the closure element such that the closure element is disposed substantially within the apparatus. The apparatus also can engage, and position the closure element substantially adjacent to, the blood vessel wall adjacent to the opening. During deployment of the closure element, the apparatus expands the closure element beyond a natural cross-section of the closure element such that the closure element, when deployed, is configured to engage a significant amount of the blood vessel wall and/or tissue. Engaging the blood vessel wall and/or tissue, the closure element is further configured to return to the natural cross-section, thereby drawing the engaged blood vessel wall and/or tissue substantially closed and/or sealed, such that hemostasis within the opening is enhanced.

32. A method for closing an opening formed in a wall of a body lumen or body tissue, comprising:
-
extending a backing member through an elongate tubular member into said opening such that said backing member engages said wall of said body lumen or said body tissue adjacent to said opening;
positioning a distal end region of a carrier assembly through said elongate tubular member adjacent to said opening, said distal end region of said carrier assembly being configured to retain a closure element substantially within said carrier assembly; and
releasing an energy storing member to deploy said closure element from said carrier assembly such that said closure element engages at least a portion of said wall of said body lumen or said body tissue whereby said opening is drawn substantially closed. - View Dependent Claims (33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49)
