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 the opening and to selectably contact the wall of the body lumen or the body tissue adjacent to the 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 abut a proximal end of said closure element in a pre-deployed state and to deploy said closure element, said pusher member enclosing at least a portion of an outer surface of said carrier member, said pusher member being adapted to move relative to said carrier member to deploy said closure element, and said closure element, when deployed, being configured to engage at least a portion of the wall of the body lumen or the body tissue whereby the opening is drawn substantially closed; and
a tubular member coupled with said carrier assembly and defining a lumen, said lumen adapted to receive a guidewire therein.

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.
