Publication number: 20150265415Abstract: Prosthetic intervertebral discs, systems including such prosthetic intervertebral discs, and methods for using the same are described. The subject prosthetic discs include upper and lower endplates separated by a compressible core member. The subject prosthetic discs exhibit stiffness in the vertical direction, torsional stiffness, bending stiffness in the saggital plane, and bending stiffness in the front plane, where the degree of these features can be controlled independently by adjusting the components, construction, and other features of the discs.Type: ApplicationFiled: March 19, 2014Publication date: September 24, 2015Inventors: Darin C. Gittings, Michael L. Reo, Janine C. Robinson, John E. Ashley, Nicholas C. Koske, Roxanne L. Richman, Elizabeth V. Wistrom, Uriel Hiram Chee

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.

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.

Publication number: 20040260278Abstract: The invention provides apparatus and methods for ablating tissue and is particularly useful for creating lesions in the heart wall for the treatment of atrial fibrillation. The apparatus has a suction well which is adhered to the tissue to be ablated. The ablating element is surrounded by the suction well. A fluid is delivered to the ablating element to conduct RF energy to the tissue and/or to cool the tissue. The device is preferably formed with a number of cells with each cell having a suction well and at least one ablating element. The device also preferably has a locking mechanism for locking one part of the device to another part of the device to form a closed loop for ablating around structures such as the pulmonary veins.Type: ApplicationFiled: April 12, 2004Publication date: December 23, 2004Inventors: Scott C.
