Patent ID: 7753935

Claim:
A method of performing an interventional procedure, the method comprising the steps of: creating an opening through a tissue wall; and moving a closure element through a first part of the tissue wall on a first side of the opening, across the opening, and through a second part of the tissue wall on a second side of the opening, bisecting the opening to assist in closure of the opening, the closure element having a first engagement element abutting the first side of the opening and the second engagement element abuts the second side of the opening; wherein a longitudinal axis of the opening intersects an external surface of the tissue at a first intersection point, an axis along which the closure element is moved intersects the external surface of the tissue at a second intersection point, the longitudinal axis of the opening intersects the axis along which the closure element is moved at a third intersection point, and a transverse axis of the lumen extends perpendicular to a longitudinal axis of the lumen through the third intersection point, the first intersection point and the second intersection point being on opposite sides of the transverse axis.
