Closure device
First Claim
1. A closure device for closing a bodily passageway, the closure device comprising:
- a first frame;
a sheet of biocompatible material attached to the first frame;
a first crossbar extending across the first frame, the first crossbar having terminal crossbar ends connectively linked to separate sites on the first frame;
a second crossbar attached to the first crossbar at a connection point; and
a second frame, the second crossbar extending across the second frame, the second crossbar having terminal crossbar ends connectively linked to separate sites on the second frame,wherein the first crossbar and the second crossbar are each configured to bend away from the connection point when the closure device is deployed to close a bodily passageway,the closure device further comprising a delivery bar linked to the second frame,wherein the delivery bar is substantially linear and has terminal delivery bar ends connectively linked to separate sites on the second frame, the terminal delivery bar ends being spaced apart from the terminal crossbar ends of the second crossbar, andwherein the delivery bar comprises a delivery bar hollow tubular member and a delivery bar wire extending through a lumen of the delivery bar hollow tubular member, the terminal delivery bar ends comprising loops extending from the terminal delivery bar wire, the loops surrounding the second frame to link the delivery bar to the second frame.

Abstract
A closure device for closing a bodily passageway is provided. The device includes first and second frames and first and second crossbars. A sheet of biocompatible material is attached to one or more of the frames. The first crossbar extends across the first frame and has terminal crossbar ends connectively linked to separate sites on the first frame; the second crossbar is similarly linked to the second frame. The crossbars are attached to each other at a connection point, and they are each configured to bend away from the connection point when the closure device is deployed to close a bodily passageway. A method of making the closure device is provided, as well as a method for closing a bodily passageway using such a device. Further, a closure device assembly is provided, including a closure device, a delivery catheter housing, and a delivery release member.
