Patent ID: 8361111

Claim:
A method for closing a patent foramen ovale in a patient, comprising: inserting a system for closing the patent foramen ovale into a heart of the patient via a percutaneous, transluminal procedure, the system comprising: a first catheter comprising a proximal end, a distal end, and a lumen extending from the proximal end to the distal end; a second catheter comprising a distal end, wherein the second catheter is movable between a retracted state where the distal end of the second catheter is enclosed within the lumen of the first catheter, and a deployed state where the distal end of the second catheter is extended beyond the distal end of the first catheter; a lining coupled to the distal end of the first catheter and the distal end of the second catheter, wherein the lining is positioned within the lumen of the first catheter when the second catheter is in the retracted state, and wherein the lining is inverted and is positioned outside the lumen of the first catheter when the second catheter is in the deployed state; and an adhesive material releasably sealed within the lining; positioning the system with the distal end of the first catheter proximate the right atrial side opening of the patent foramen ovale with the second catheter in the retracted state; inverting the lining into the patent foramen, by deploying the second catheter, thereby extending the distal end of the second catheter beyond the distal end of the first catheter; applying the adhesive to tissues of the patient in the patent foramen ovale by contacting the tissues with the inverted liner, wherein deploying the second catheter causes the adhesive to be released from the lining and exposed to the tissues of the patient; retracting the lining from the patent foramen ovale; and withdrawing the system from the patient.
