Patent number: 8721636Abstract: The invention provides apparatus and methods for mapping conduction pathways and creating lesions in the heart wall for the treatment of atrial fibrillation. The apparatus may include at least one epicardial ablation probe having a plurality of electrodes for creating a lesion. The apparatus and method facilitate the formation of a lesion which electrically isolates the pulmonary veins from the surrounding myocardium.Type: GrantFiled: May 13, 2005Date of Patent: May 13, 2014Assignee: St. Jude Medical, Atrial Fibrillation Division, Inc.Inventors: Matthias Vaska, Banjamin Pless, David A. Gallup, Jack E. Ulstad, Jr., Scott C. Anderson, Roxanne L. Richman

Publication number: 20120271334Abstract: A control system alters one or more characteristics of an ablating element to ablate tissue. In one aspect, the control system delivers energy nearer to the surface of the tissue by changing the frequency or power. In another aspect, the ablating element delivers focused ultrasound which is focused in at least one dimension. The ablating device may also have a number of ablating elements with different characteristics such as focal length.Type: ApplicationFiled: July 2, 2012Publication date: October 25, 2012Inventors: Benjamin Pless, Scott C. Anderson, Jonathan L. Podmore, Matthias Vaska, John E. Crowe, Roxanne L. Richman, Timothy Ciciarelli, David A. Gallup, Jack E. Ulstad, JR.

Patent number: 8211096Abstract: A control system alters one or more characteristics of an ablating element to ablate tissue. In one aspect, the control system delivers energy nearer to the surface of the tissue by changing the frequency or power. In another aspect, the ablating element delivers focused ultrasound which is focused in at least one dimension. The ablating device may also have a number of ablating elements with different characteristics such as focal length. The invention provides an ablation apparatus and methods for ablating tissue wherein the ablation apparatus may have ablating elements that are moveable relative to the tissue to be ablated without the need to relocate the apparatus as a whole.Type: GrantFiled: August 9, 2007Date of Patent: July 3, 2012Assignee: St. Jude Medical, Atrial Fibrillation Division, Inc.Inventors: Benjamin Pless, Scott C. Anderson, Jonathan L. Podmore, Matthias Vaska, John E. Crowe, Roxanne L. Richman, Timothy Ciciarelli, David A. Gallup, Jack E. Ulstad, Jr.
