Patent ID: 8277482

Claim:
A method for closing a body opening in a patient comprising: positioning a delivery catheter having a proximal end, a distal end, and a lumen formed through the proximal and distal ends within the body opening, the delivery catheter including a closure device collapsibly disposed within the lumen at the distal end of the delivery catheter, the closure device including a distal occluding body having an expandable distal umbrella frame and a proximal occluding body having an expandable proximal umbrella frame, the distal frame including a plurality of struts having first ends attached to a distal end of a center rod, the proximal frame including a center ring and a plurality of struts having first ends attached to the center ring, the center ring being slidable along the center rod, the struts of each frame being connected to a biocompatible sheet material, the center rod defining a longitudinal axis, the distal frame struts extending from the distal end of the center rod in a generally parallel, axial direction with respect to the longitudinal axis when the distal frame is in a collapsed configuration and in a generally perpendicular, radial direction with respect to the longitudinal axis when the distal frame is in an expanded configuration, the proximal frame struts extending from the center ring in a generally parallel, axial direction with respect to the longitudinal axis when the proximal frame is in a collapsed configuration and in a generally perpendicular, radial direction with respect to the longitudinal axis when the proximal frame is in an expanded configuration, each strut of the distal frame extending from the first end and terminating with an eyelet, the closure device further including at least one drawstring threaded through the eyelets of the distal frame and through the center ring of the proximal frame to connect the distal and proximal occluding bodies to one another, the at least one drawstring extending proximally from the center ring; and deploying the closure device from the delivery catheter about the body opening such that the distal frame of the distal occluding body expands to its expanded configuration at a distal end of the body opening and the proximal frame of the proximal occluding body expands to its expanded configuration at an opposing proximal end of the body opening.
