  • Publication number: 20120130362
    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: 8185213
    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.

  • Publication number: 20120109021
    Abstract: A transducer supported by a positioning arrangement is placed within a renal artery at a desired location that is a predetermined distance from a reflector equal to an odd number of quarter wavelengths of acoustic energy emitted by the transducer. The positioning arrangement is actuated to transition from a low-profile introduction configuration to a deployed configuration within the renal artery thereby stabilizing the transducer at a desired location. Acoustic energy is emitted by the transducer so that it propagates axially along an outer surface of the target vessel to impinge the reflector, which can be biological or artificial. The emitted energy builds up to resonance at a point of reflection defined by a location of the reflector, and the amount of energy build up is sufficient to ablate perivascular renal nerves in the vicinity of the reflector.

  • Publication number: 20120059241
    Abstract: A medical imaging assembly includes a sheath with a lumen. An imaging core is disposed at one end of an imaging core shaft disposed in the lumen. The imaging core shaft bends along a shape memory region when the imaging core is extended from the lumen. The imaging core includes a transducer to image patient tissue, a mirror to redirect acoustic signals between the transducer and patient tissue, and a magnet to drive rotation of the mirror. The magnet is rotatable by a magnetic field generated at the location of the magnet. An imaging core shaft rotator rotates the imaging core shaft such that, when the imaging core is extended from the lumen, rotation of the imaging core shaft causes radial rotation of the imaging core about the sheath. The imaging core shaft rotator includes rotatable imaging core shaft magnets fixedly disposed over a portion of the imaging core shaft.
