  • Publication number: 20190374244
    Abstract: Systems for nerve and tissue modulation are disclosed. An example system may include a first elongate element having a distal end and a proximal end and having at least one nerve modulation element disposed adjacent the distal end. The nerve modulation element may be positioned or moveable to target a particular target region. The nerve modulation element may be an ultrasound transducer. The nerve modulation element may be configured to be operated at a low intensity to provide a thermal nerve block or a high intensity to effect tissue modulation.

  • Publication number: 20190366081
    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: 20150105764
    Abstract: A cryotherapy balloon catheter includes a compliant cryotherapy balloon comprising a distal balloon section dimensioned for placement within a renal artery and a proximal balloon section dimensioned to abut against an ostium of the renal artery and extend into at least a portion of the abdominal aorta. The compliant balloon has a diameter that varies non-uniformly along a length of the compliant balloon, such that a diameter at the proximal balloon section is larger than a diameter of the distal balloon section. The cryotherapy balloon catheter may be configured to deliver cryogenic therapy to at least the ostium of the renal artery sufficient to irreversibly terminate renal sympathetic nerve activity, such as by causing neurotmesis of renal nerve fibers and ganglia at the ostium of the renal artery.

  • Publication number: 20140330069
    Abstract: A percutaneous pumping system for providing hemodynamic support to a patient includes a pumping sleeve that defines a lumen extending along the length of the pumping sleeve. The pumping sleeve is configured and arranged for insertion into patient vasculature. At least one rotatable magnet is disposed in the pumping sleeve. The at least one first magnet is configured and arranged to be driven to rotate by a magnetic field generated external to the pumping sleeve. At least one impeller is coupled to the at least one magnet. Rotation of the at least one magnet causes a corresponding rotation of the at least one impeller. An anchoring arrangement is coupled to the pumping sleeve. The anchoring arrangement is configured and arranged to anchor the pumping sleeve at a target pumping location when the pumping sleeve is inserted into patient vasculature.
