Abstract
Methods and apparatus for treatment of anatomic defects in human tissues, such as patent foramen ovale (PFO), atrial or ventricular septal defects, left atrial appendage, patent ductus arteriosus, blood vessel wall defects and certain electrophysiological defects, involve positioning a distal end of an elongate catheter device at the site of the anatomic defect, engaging tissues at the site of the anatomic defect to bring the tissues together, and applying energy to the tissues with the catheter device to substantially close the anatomic defect acutely. Apparatus generally includes an elongate catheter having a proximal end and a distal end, a vacuum application member coupled with the distal end for engaging tissues at the site of the anatomic defect and applying vacuum to the tissues to bring them together, and at least one energy transmission member coupled with the vacuum application member for applying energy to tissues at the site of the anatomic defect to substantially close the defect acutely.
