Closure devices, systems, and methods

摘要

The present disclosure includes vessel closure devices, systems, and methods. A closure device configured to close an opening in a body lumen may include an elongate member having a distal end and a proximal end. An anchor member may be disposed on the elongate member proximate the distal end of the elongate member. A cap member may also be disposed on the elongate member a distance from the distal end of the elongate member. The anchor member and the cap member cooperate to close the opening in the body lumen.

主权项

1. A closure system configured to close an opening in a body lumen, the closure system comprising:
a generally tubular outer member having a distal opening and a proximal opening; a generally tubular intermediate member disposed at least partially within the outer member; a generally tubular inner member disposed at least partially within the generally tubular intermediate member, the generally tubular inner member including a lumen; and a closure device disposed at least partially within the outer member and around at least a portion of an outer surface of the generally tubular inner member extending from a distal end towards a proximal end of the generally tubular inner member, the closure device comprising:
a suture having a distal end and a proximal end;a monolithic anchor member connected to the suture proximate the distal end of the suture and at least partially wrapped around to at least partially encircle a portion of the generally tubular inner member, the anchor member being elastic such that the anchor member conforms to an inner surface of the body lumen, a knot affixed to a proximal face of the monolithic anchor member; anda cap member connected to the suture a distance from the distal end of the suture, the cap member being configured to conform to an outer surface of the body lumen, wherein the anchor member and the cap member being deformed to close the opening in the body lumen with a convex-like surface of the cap member being disposed toward the monolithic anchor member,wherein the suture extends distally from the distal end of the generally tubular inner member and distal the monolithic anchor in a pre-deployed, delivery configuration.
