  • Publication number: 20150265415
    Abstract: 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.

  • Publication number: 20120271334
    Abstract: 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.

  • Publication number: 20040260278
    Abstract: 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.
