Abstract

Described are method and device for closing a passageway in a body, for example a patent foramen ovale (PFO) in a heart, and related methods of using such closure devices for closing the passageway. The method includes locating a distal end of a closure device adjacent to the passageway. The closure device may include a closure line with proximal and distal ends, an expandable tissue anchor located along the distal end of the closure line, and an expandable occluder member located along the proximal end of the closure line. The expandable tissue anchor is deployed into tissue adjacent to the passageway. The expandable occluder member is deployed adjacent to the passageway such that the expandable occluder member substantially covers the second opening to the passageway.

Claims3

Dependent claims

A method of closing a persistent passageway in a heart between a septum primum and septum secundum, the passageway having a first and a second open end, comprising:

locating a distal end of a closure device adjacent to the persistent passageway, the closure device having a closure line with proximal and distal ends, an expandable tissue anchor located along the distal end of the closure line, and an expandable occluder member located along the proximal end of the closure line;
deploying the expandable tissue anchor into a septal tissue of only one of the septum primum and septum secundum adjacent to the persistent passageway;
deploying the expandable occluder member adjacent to the persistent passageway by piercing a surface of the tissue with the expandable tissue anchor and expanding the tissue anchor within the septal tissue without the anchor detaching from the septal tissue such that the expandable occluder member substantially covers the second opening to the persistent passageway.

Dependencies are inferred from the claim text.
