主权项

1. A closure system comprising:
a handle member; a tube set configured to deliver or deploy a closure element, the tube set having a distal end and a proximal end, the proximal end of the tube set being coupled to the handle member; an inner lumen disposed at least partially within the tube set; a plunger member movably coupled to the handle member; and an anchor member at least partially disposed within the inner lumen, the anchor member comprising an anchor portion, a first elongate portion, and a second elongate portion, the anchor portion being disposed in the inner lumen in an initial configuration and configured to move to an expanded configuration in a transverse plane to said elongate portion once deployed from the inner lumen without additional external force, the expanded configuration including a first portion and a second portion, the second portion being an inverted mirror image of the first portion about an intersection between the first portion and the second portion, the first elongate portion, the second elongate portion, the first portion, and the inverted second portion are continuously connected the anchor member configured to locate the closure system within a body lumen, the anchor member being configured to be retracted through the closure element.
