Patent ID: 8052678

Claim:
A catheter device for treating a patent foramen ovale in a heart, the heart including a septum secundum tissue and a septum primum tissue adjacent the patent foramen ovale, the catheter device comprising: an elongate catheter body having a proximal end and a distal end; a first tissue apposition member and a second tissue apposition member located at or near the catheter body distal end and configured to move towards each other so as to bring the septum primum and septum secundum tissues adjacent the patent foramen ovale at least partially together, the first tissue apposition member being configured to contact the septum secundum tissue adjacent the patent foramen ovale from a right atrium of the heart without penetrating the septum secundum tissue, the second tissue appostion member being configured to advance through the septum primum tissue of the heart; and at least one energy transmission member at or near the distal end for applying energy to the tissues to substantially close the patent foramen ovale acutely.
