Patent number: 7635353Abstract: The instant invention is directed toward transseptal puncture needles and transseptal puncture needle assemblies. More specifically, it relates to curved transseptal puncture needles and needle assemblies that facilitate insertion through curved transseptal introducers. Each curved transseptal puncture needle includes a needle tip with a tangential back bevel configuration, a reverse tangential back bevel configuration, or a conical reverse bevel configuration. The axial orientation of the needle tip relative to the needle curvature, whether on the concave side or convex side of the curved transseptal puncture needle, provides additional benefits. The leading edge of the needle tip is located at a distal end of an inner needle tube, and the leading edge of the needle tip may be positioned away from an outer surface of the inner needle tube and adjacent to an inner surface of the inner needle tube.Type: GrantFiled: September 22, 2004Date of Patent: December 22, 2009Assignee: St. Jude Medical, Atrial Fibrillation Division, Inc.Inventors: Ravisankar Gurusamy, John D. Ockuly, Hans Schnellmann, James A. Hassett

Patent number: 6780181Abstract: A linear lesion ablation catheter includes a conductive ablating portion having a predetermined resistivity profile for ablating tissue in a generally even temperature profile. In one embodiment, the conductive ablating portion is disposed on a distal portion of an elongate flexible member and has a resistance that increases exponentially along its length from a center of the ablating portion to a non-infinite value at opposite ends of the ablating portion. The ablating portion is adapted to produce a generally even temperature profile along a length of its surface when the ablating portion is in contact with a target tissue within a patient's body. In one example, the conductive ablating portion comprises a plurality of electrically connected conductive regions which extend from the center to the opposite ends of the ablating portion.Type: GrantFiled: August 29, 2001Date of Patent: August 24, 2004Assignee: St. Jude Medical, Daig Division, Inc.Inventors: Mark W. Kroll, John D. Ockuly, Rajesh Pendakanti
