  • Patent number: 9421101
    Abstract: An assembly for providing localized pressure to a region of a patient's heart to improve heart functioning, including: (a) a jacket made of a flexible biocompatible material, the jacket having an open top end that is received around the heart and a bottom portion that is received around the apex of the heart; and (b) at least one inflatable bladder disposed on an interior surface of the jacket, the inflatable bladder having an inelastic outer surface positioned adjacent to the jacket and an elastic inner surface such that inflation of the bladder causes the bladder to deform substantially inwardly to exert localized pressure against a region of the heart.

  • Patent number: 8014874
    Abstract: Connection structures on an extra-vascular electrode lead body improve strain relief and strengthen the transition region where electrical conductors carried by the lead body are joined to individual electrodes at the distal end of the lead. The electrodes include structure or mechanisms for externally securing the electrode assembly to a body part. A first connection structure is located on the lead body proximal the electrodes to anchor the lead body to a first anchor location in the body that generally moves in concert with the body part. A second connection structure is located on the lead body proximal to the first connection structure to anchor the lead body to a second anchor location that is at least partially independent of movement of the body part. The first and second anchor location are offset by a distance that is less than a distance between the first and second connection structures to provide strain relief for the electrodes.

  • Publication number: 20080046054
    Abstract: An electrode assembly for implantation around an elongate biological structure such as, for example, a blood vessel, includes at least one belt mechanism for securing the electrode assembly around the outer surface of the elongate biological structure. Each of the at least one belt mechanism includes a strap and a buckle. The assembly has a length that is sufficient to permit wrapping it around the outer surface of the elongate biological structure. The buckle can be attached to, or integrally formed in, the base, and functions to retain a portion of the strap when the strap is engaged with the buckle.

  • Publication number: 20070282385
    Abstract: A lockout connector arrangement for implantable medical devices having at least one port for receiving a non-cardiac lead connector selectively permits only certain electrical leads to be connected to the implantable medical device. A lead connector pin of a non-cardiac lead connector is specially designed to be larger than a DF-1 lead connector pin, but smaller than an IS-1 lead connector pin. A corresponding header of implantable pulse generator has a connector port for a non-cardiac lead with a proximal-most portion that is larger than the DF-1 lead connector pin, but smaller than the IS-1 lead connector pin; and otherwise generally consistent with the other dimensions of an ISO standard IS-1 pacemaker lead connector.

  • Patent number: 6740108
    Abstract: A thermal therapy catheter for preferentially treating tissue adjacent to a body lumen includes a catheter shaft that is insertable into the body lumen. An energy-emitting element is carried by the catheter shaft, and is operable to radiate a generally symmetrical energy pattern. The catheter shaft includes a plurality of cooling lumens around the energy-emitting element, configured for circulation of a fluid therethrough. An attenuating element is located in at least one of the plurality of cooling lumens and is arranged to modify the generally symmetrical energy pattern radiated by the energy-emitting element to deliver an asymmetrical energy pattern to the tissue adjacent to the body lumen.

  • Patent number: 6496737
    Abstract: A thermal therapy catheter includes a catheter shaft having an outer surface that is insertable into the body lumen. The catheter shaft carries an energy-emitting element. A multi-lobe balloon is positioned around the outer surface of the catheter shaft adjacent to the energy-emitting element, with opposing ends of the multi-lobe balloon being sealingly connected to the catheter shaft to form a chamber between the multi-lobe balloon and the outer surface of the catheter shaft. Fluid is circulated between the outer surface of the catheter shaft and the multi-lobe balloon in a defined fluid flow path to firmly contact the wall of the body lumen and thereby cool the body lumen tissue while thermally treating targeted tissue at a depth from the body lumen wall.
