Patent number: 7115110Abstract: Disclosed is a closure catheter, for closing a body cavity such as a vessel, or the left atrial appendage of the heart. The closure catheter includes a plurality of deployable tissue anchors, which may be laterally deployed into surrounding tissue. The anchors may thereafter be used to draw the tissue radially inwardly, to close the body cavity. Methods are also disclosed.Type: GrantFiled: October 30, 2003Date of Patent: October 3, 2006Assignee: ev3 Sunnyvale, Inc.Inventors: Andrew G. C. Frazier, Erik J. van der Burg, Michael D. Lesh

Patent number: 6650923Abstract: Disclosed is an access catheter for identifying and providing access through a tissue structure such as the fossa ovalis on the intraatrial septum. The access catheter comprises an elongate flexible tubular body having a proximal and a distal end, and a retractable piercing structure such as a needle carried by the distal end. A detector such as a red, green, and blue light detector is associated with the access catheter, such that placement of the distal end of the catheter against the fossa ovalis can be detected. The piercing structure is thereafter advanceable to provide access to the left atrium through the fossa ovalis.Type: GrantFiled: April 13, 2000Date of Patent: November 18, 2003Assignee: ev3 Sunnyvale, Inc.Inventors: Michael D. Lesh, Alex K. Khairkahan, Erik J. van der Burg
