Patent ID: 7377936

Claim:
A method of deploying a defect closure device, comprising: providing an elongate delivery catheter having a lumen; providing a closure device having expandable proximal and distal frames, the proximal and distal frames being coupled to each other and wherein the distal frame includes a plurality of loops originating from a central attachment region and extending radially outwardly from the central attachment region and including a plurality of flexible joints configured to facilitate collapse of the distal frame upon retrieval, the plurality of flexible joints being disposed on the central attachment region; reversibly delivering the closure device from the catheter into a defect of a patient such that the proximal and distal frames are fully expanded on opposite sides of the defect and wherein the closure device is capable of being retracted back into the lumen from its fully expanded configuration within the patient by withdrawing a drawstring attached to the proximal frame to collapse the proximal frame and by collapsing the distal frame along the plurality of flexible joints.
