Patent ID: 7867249

Claim:
An apparatus for delivering a closure element to an opening formed in a wall of a body lumen or body tissue, comprising: a locator assembly having a distal end region and a locator control system coupled to a proximal end region of said locator assembly, said locator control system being configured to selectively control said distal end region of said locator assembly between an unexpanded state and an expanded state for engaging said wall of said body lumen or said body tissue adjacent to said opening; a carrier assembly coupled with said locator assembly, said carrier assembly comprising a carrier member for retaining said closure element in a substantially tubular configuration within said carrier assembly, and a pusher member adapted to deploy said closure element; a cover member configured to retain said closure element, said cover member having a distal end region and a proximal end region, said distal end region of said cover member including one or more longitudinal extensions extending distally and substantially radially inwardly with respect to said proximal end region and being configured to expand radially; an energy storing member associated with said carrier assembly and said locator control system, said energy storing member configured to cause a proximal end of said pusher member to move distally from a proximal end of said carrier member and to move a portion of said proximal end region of the locator control system proximally to disengage the distal end region of the locator assembly from engaging said wall of said body lumen or said body tissue.
