    摘要: 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.

    摘要: 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.

    摘要: 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.
