First Claim
1. An apparatus for delivering a closure element to an opening formed in tissue, the apparatus comprising:
- a first grasping portion;
a second grasping portion movable toward the first grasping portion; and
a distal locator expandable with distal movement of a movable proximal member,wherein, the distal movement of movable proximal member expands said distal locator to an expanded state, moves the closure element distally, and moves said second grasping portion toward said first grasping portion.

Abstract
An apparatus for placement into an opening formed in a wall of a body lumen to deploy a closure element. The apparatus comprising a housing having a handle portion formed at a distal end, the handle portion configured to be engaged by a user when advancing the housing to deploy the closure element. A locator assembly and a carrier assembly are at least partially received in the housing. The locator assembly can have one or more expansion members that can selectably contact the wall of the body lumen and a proximal end configured to cooperate with a portion of a locator control system operable to expand the one or more expansion members. A triggering system cooperates with the locator assembly and is moveable toward the one or more expansion members of the locator assembly upon the locator control system being operated to expand the one or more expansion members.

9. An apparatus for delivering a closure element to an opening formed in tissue, the apparatus comprising:
-
a first grasping portion; a second shaped grasping portion movable toward the first grasping portion; and a distal locator expandable with distal movement of a movable proximal member, the movable proximal member being operatively connected to the second shaped portion and the distal locator, wherein, the distal movement of movable proximal member simultaneously expands said distal locator to an expanded state, moves the closure element distally, and moves said second shaped grasping portion toward said first grasping portion. - View Dependent Claims (10, 11, 12, 13)

14. An apparatus for delivering a closure element to an opening formed in tissue, the apparatus comprising:
-
a first shaped grasping portion formed in a housing; a second shaped grasping portion movable toward the first shaped grasping portion and movable relative to the housing; and a distal locator expandable with distal movement of a movable proximal member, the movable proximal member and the housing fitting together with a portion of the movable proximal member sliding within the housing from a proximal end of the housing toward a distal end of the housing, the movable proximal being operatively connected to both the second shaped grasping portion and the distal locator, wherein, the distal movement of movable proximal member expands said distal locator from an unexpanded state to an expanded state, moves the closure element distally, and moves said second shaped grasping portion toward said first shaped grasping portion. - View Dependent Claims (15, 16, 17, 18, 19, 20)
