Closure device and method of closing a bodily opening
First Claim
1. A closure device comprising:
- only one circumferential frame defining a single frame plane;
a first crossbar extending across the frame, the first crossbar having a central portion and terminal crossbar ends connectively linked to separate sites on the frame;
a bar-shaped first anchor containing two terminal first anchor ends and a central portion attached to the central portion of the first cross bar; and
a single sheet of biocompatible material, the sheet of biocompatible material having a periphery attached to the frame,wherein each of the frame, the first crossbar, and the first anchor comprises at least one flexible, substantially linear structure,wherein the first anchor is only indirectly connected to the frame via the first crossbar andwherein the first crossbar is configured to extend in an arc concave to the frame plane when deployed, and wherein the first anchor is configured to extend in an arc convex to the frame plane when deployed.

Abstract
In one embodiment, a device for closing or occluding ASDs and PFOs, or other bodily passageways, includes a circumferential frame, a sheet of biocompatible material attached to the frame, and at least one anchor attached to the sheet of biocompatible material. In another embodiment, the closure device includes a circumferential frame, at least one crossbar extending across and attached to the frame, at least one anchor connected to at least one crossbar; and at least one sheet of biocompatible material (such as ECM material) attached to the frame. The anchor includes at least one grasping member having a structure, such as a wired loop, which is configured for releasable attachment to a delivery release member, which facilitates delivery of a closure device collapsibly disposed in a delivery catheter. Alternatively, one or more anchor end pairs may be connected to a delivery bar enhancing delivery and retrieval of the device.

14. A closure device comprising:
-
only one frame, the frame defining a frame plane; a first crossbar extending across the frame, the first crossbar having terminal crossbar ends connectively linked to separate sites on the frame; a second crossbar extending across the frame, the second crossbar having terminal crossbar ends connectively linked to separate sites on the frame; a first anchor containing two terminal first anchor ends; a second anchor containing two terminal second anchor ends; a delivery bar joined between a first pair of terminal anchor ends on one delivery bar end and a second pair of terminal anchor ends on a second delivery bar end; and a sheet of biocompatible material attached to the frame, wherein the first crossbar is configured to extend in an arc concave to the frame plane when deployed, and wherein the first anchor is configured to extend in an arc convex to the frame plane when deployed, wherein each of the delivery bar, the first anchor, the second anchor, the first crossbar, and the second crossbar comprises a coil and terminally disposed wire loops; wherein one or more wires interconnect the terminally disposed wire loops of the delivery bar with terminally disposed wire loops of the first and second anchors, and wherein one or more wires interconnect the terminally disposed wire loops of the first and second crossbars with the frame. - View Dependent Claims (15)
