Energy based devices and methods for treatment of anatomic tissue defects
First Claim
1. A method of treating an anatomic defect in human tissue, the method comprising:
- positioning a distal end of an elongate catheter device at the site of the anatomic defect, wherein positioning the distal end comprises advancing the catheter device intravascularly over a guidewire extending into or through 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,and wherein the anatomic defect is selected from the group consisting of a patent foramen ovale, an atrial septal defect, a left atrial appendage and a ventricular septal defect.

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 arteriosis, 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.

18. A method of treating a patent foramen ovale in a heart, the method comprising:
-
positioning a distal end of an elongate catheter device adjacent the patent foramen ovale; engaging tissues of the patent foramen ovale by applying a vacuum at a first pressure through the catheter device to bring the tissues together; and applying energy to the tissues with the catheter device to substantially close the patent foramen ovale acutely. - View Dependent Claims (19, 20, 21, 22, 23, 24)
