  • Patent number: 9463062
    Abstract: A catheter includes a flexible shaft having a lumen arrangement and a length sufficient to access a target vessel of a patient. A balloon at the distal end of the shaft is fluidly coupled to the lumen arrangement. The balloon body comprises a first material and a second material different from the first material. The second material comprises a hydrophilic polymer that becomes electrically conductive in response to absorption of the conductive fluid. The fluid conductive regions facilitate perfusion of the conductive fluid through the balloon body to an inner wall of the target vessel during ablation of perivascular tissues. A cooling arrangement is configured for one of receiving a thermal transfer fluid from the lumen arrangement or facilitating perfusion of blood passing through the target vessel to cool the balloon body during ablation of the perivascular tissues.

  • Publication number: 20160175599
    Abstract: Various configurations of systems that employ leadless electrodes to provide pacing therapy are provided. In one example, a system that provides multiple sites for pacing of myocardium of a heart includes wireless pacing electrodes that are implantable at sites proximate the myocardium using a percutaneous, transluminal, catheter delivery system. Each of the electrodes contains a source of electrical energy for pacing the myocardium and is adapted to receive electromagnetic energy from a source outside the myocardium. The system also includes a source adapted for placement outside the myocardium and that uses locally measured electrocardiograms to synchronize pacing of the heart by sending electromagnetic commands to the electrodes to pace the myocardium surrounding the electrodes. Also disclosed is various configurations of such systems, wireless electrode assemblies, and delivery catheters for delivering and implanting the electrode assemblies.

  • Patent number: 9308374
    Abstract: Some embodiments of an electrical stimulation system employ wireless electrode assemblies to provide pacing therapy, defibrillation therapy, or other stimulation therapy. In certain embodiments, the wireless electrode assemblies may include a guide wire channel so that each electrode assembly can be advanced over a guide wire instrument through the endocardium. For example, a distal tip portion of a guide wire instrument can penetrate through the endocardium and into the myocardial wall of a heart chamber, and the electrode assembly may then be advanced over the guide wire and into the heart chamber wall. In such circumstances, the guide wire instrument (and other portions of the delivery system) can be retracted from the heart chamber wall, thereby leaving the electrode assembly embedded in the heart tissue.

  • Patent number: 9192790
    Abstract: Acoustic energy is delivered to innervated vascular that contributes to renal sympathetic nerve activity, such as innervated tissue of the renal artery and abdominal aorta. Focused acoustic energy is delivered via an intravascular device of sufficient power to ablate innervated renal or aortal tissue. Focused acoustic energy may be delivered via an intravascular or extracorporeal device to image and locate target innervated renal or aortal tissue. Intravascular, extravascular, or transvascular focused ultrasound devices provide for high precision denervation of innervated vascular to terminate renal sympathetic nerve activity.

  • Patent number: 9089340
    Abstract: An imaging assembly comprises a catheter having a distal end and a proximal end, an ablation tip at the distal end of the catheter, and an imaging device disposed within the ablation tip. The catheter defines a catheter lumen that extends from the proximal end to the distal end. The catheter is configured and arranged for insertion into a body lumen such as a blood vessel or heart chamber. The ablation tip has a wall that defines a lumen in communication with the lumen of the catheter. The imaging device is disposed within the lumen of the ablation tip, and is configured to transmit pulsed acoustic waves for generating images of body tissue at a target ablation site within the body.

  • Patent number: 9060761
    Abstract: A flexible catheter includes a magnetically permeable element provided at its distal end. The magnetically permeable element is configured for placement within the renal artery. External coils, positionable on anterior and posterior portions of a patient in proximity to the renal artery, are coupled to a generator which energizes the external coils to create a high-frequency oscillating magnetic field in body tissue between the external coils including the renal artery and perivascular renal nerve tissue. The magnetically permeable element serves to concentrate the magnetic field in a region near the renal artery. The concentrated magnetic field induces high frequency electric current sufficient to ablate the perivascular renal nerve tissue proximate the renal artery. A cooling arrangement can be provided at the catheter's distal end and configured to provide cooling to the renal artery during ablation of the perivascular renal nerve tissue.

  • Patent number: 9042565
    Abstract: A method and apparatus processes multi-channel audio by encoding, transmitting or recording “dry” audio tracks or “stems” in synchronous relationship with time-variable metadata controlled by a content producer and representing a desired degree and quality of diffusion. Audio tracks are compressed and transmitted in connection with synchronized metadata representing diffusion and preferably also mix and delay parameters. The separation of audio stems from diffusion metadata facilitates the customization of playback at the receiver, taking into account the characteristics of local playback environment.
