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.
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.
1. A method for delivering a closure element to an opening formed in a wall of a body lumen, the method comprising: inserting a distal end region of an apparatus into the opening in the wall of the body lumen, the distal end region being selectively movable between an unexpanded state and an expande
1. A method for delivering a closure element to an opening formed in a wall of a body lumen, the method comprising: inserting a distal end region of an apparatus into the opening in the wall of the body lumen, the distal end region being selectively movable between an unexpanded state and an expanded state, the distal end region being usable as a locator in the expanded state; andactivating a proximal portion of the apparatus to simultaneously transition the distal end region from the unexpanded state to the expanded state and advance a trigger extension, which is configured to distally advance a closure device, distally toward the distal end region in a single step. 2. The method of claim 1, wherein activating the proximal portion of the apparatus also simultaneously advances a carrier assembly distally toward the distal end region in the single step. 3. The method of claim 1, further comprising, after activating the proximal portion, advancing the trigger extension distally further toward the distal end region to deploy a closure element from the apparatus to close the opening formed in the wall of the body lumen. 4. The method of claim 3, wherein advancing the trigger extension distally further toward the distal end region transition the distal end region from the expanded state to the unexpanded state. 5. The method of claim 1, wherein activating the proximal portion of the apparatus comprises distally advancing a plunger. 6. The method of claim 5, further comprising locking the plunger in a distal position after distally advancing the plunger. 7. The method of claim 1, wherein the trigger extension is releasably held in place prior to activating the proximal portion of the apparatus. 8. The method of claim 7, wherein activating the proximal portion of the apparatus releases the trigger extension, thereby enabling the trigger extension to advance distally toward the distal end region. 9. The method of claim 1, wherein activating the proximal portion of the apparatus comprises coupling together at least two components of the apparatus. 10. The method of claim 9, wherein coupling together at least two components of the apparatus comprises coupling together a spring retainer and a tubular body block. 11. A method for delivering a closure element to an opening formed in a wall of a body lumen, the method comprising: inserting a distal end region of an apparatus into the opening in the wall of the body lumen, the distal end region being movable between an unexpanded state and an expanded state;activating a proximal portion of the apparatus towards a distally positioned grip portion formed on a housing of the apparatus and into a proximal end of the housing, activating the proximal portion to simultaneously transition the distal end region from the unexpanded state to the expanded state and contact a portion of a trigger extension to advance the trigger extension distally toward the distal end region in a single step; anddeploying a closure element from the apparatus to close the opening formed in the wall of the body lumen, deploying the closure element comprising advancing the trigger extension distally further toward the distal end region after activating the proximal portion. 12. The method of claim 11, wherein activating a proximal portion of the apparatus comprises distally advancing a plunger toward the distal end region. 13. The method of claim 12, wherein distally advancing the plunger distally advances a carrier assembly toward the distal end region. 14. The method of claim 13, wherein advancing the trigger extension distally further toward the distal end region after activating the proximal portion advances the carrier assembly further toward the distal end region. 15. The method of claim 11, further comprising transitioning the distal end region from the expanded state to the unexpanded state upon deployment of the closure element from the apparatus. 16. A method for delivering a closure element to an opening formed in a wall of a body lumen, the method comprising: inserting a distal end region of an apparatus into the opening in the wall of the body lumen, the distal end region being movable between an unexpanded state and an expanded state;performing a first activation step, the first activation step simultaneously transitioning the distal end region from the unexpanded state to the expanded state, advancing a carrier assembly distally toward the distal end region, and advancing a trigger extension distally toward a distal end of a handle in a single step;performing a second activation step after performing the first activation step, the second activation step advancing the trigger extension distally to the distal end of the housing to move a closure element towards the opening; anddeploying the closure element from the apparatus to close the opening formed in the wall of the body lumen. 17. The method of claim 16, wherein the second activation step comprises advancing the trigger extension distally further toward the handle. 18. The method of claim 16, wherein performing the second activation step transitions the distal end region from the expanded state to the unexpanded state. 19. The method of claim 16, wherein performing the first activation step couples together at least two components of the apparatus. 20. The method of claim 19, wherein performing the second activation step decouples at least two components of the apparatus.
