Patent ID: 8313497

Claim:
An apparatus for delivering a closure element to an opening formed in a wall of a body lumen, the apparatus comprising: a housing having a distally positioned finger grip extending in a first direction, a proximal end, and a longitudinal axis, a locator assembly having a distal end region and a proximal end region, the distal end region having an expanded state and an unexpanded state and the proximal end being configured to cooperate with a movable plunger, the movable plunger being slidably disposed within the proximal end of said housing and distally advanceable into the proximal end of the housing, a carrier assembly coupled with said locating assembly, said carrier assembly retaining the closure element in a substantially tubular configuration within said carrier assembly; and a triggering system including a trigger extension, said trigger extension extending from said housing in said first direction, said triggering system, said locator assembly, and said movable plunger being operatively connected together and configured to advance distally together under movement of said movable plunger distally into said proximal end of said housing, said distal movement of said movable plunger simultaneously transitions said distal end region of said locator assembly to the expanded state and advances said trigger extension distally toward said distally positioned finger grip.
