A device for closing a tissue opening includes a proximal housing portion having a first portion, a second portion, a third portion, and a fourth portion. The first portion and the fourth portion extending transversely to a longitudinal axis of the proximal housing portion on opposite sides of the proximal housing portion. A distal portion extends from the proximal housing portion. At least the second portion and the third portion are configured to move toward the first portion.

Clip applier and methods of use

A method for delivering a closure element to an opening formed in a wall of a body lumen. The method includes inserting a distal end region of an apparatus into the opening in the wall of the body lumen, moving a third grasping portion toward the first grasping portion to limit movement of the distal end of the apparatus relative to the opening in the wall of the body lumen, and moving a second grasping portion toward the first grasping portion to advance the closure element distally. The second grasping portion and third grasping portion are movable toward the first grasping portion.

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.

A locator assembly and a carrier assembly are at least partially received in the housing. The locator assembly can have a distal end that contains notches or a shaped edge which are designed to help prevent the misfiring of the tines of the closure element. 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.
