摘要： A stent assembly includes a stent, a covering on at least a portion of the stent, and a string encircling at least a portion of the covering. The string is releasably engaged to the covering or stent or both the covering and the stent. The string can be adhered to the stent, or the stent assembly, to the covering of the stent assembly, or both the covering and the stent. The string can be wrapped around the stent or covering in an interwoven loop or knit pattern. The covering can be made to overlap a perforation in a body lumen such as an artery or blood vessel and prevent bleeding.

摘要： An apparatus and method can receive wireless energy using a wireless electrostimulation electrode assembly. In certain examples, at least some of the received wireless energy can be delivered as an electrostimulation to a heart. In certain examples, the wireless electrostimulation electrode can be mechanically supported at least partially using a ring formed by an annulus of a mitral valve of the heart. In certain examples, the wireless electrostimulation electrode assembly can be configured to be intravascularly delivered to an implant location within a chamber of the heart at the annulus of the mitral valve of the heart, and can fit entirely within the heart.

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.

摘要： Devices, systems, and methods facilitate modification of renal sympathetic nerve activity using a force generating arrangement. A device for mechanically modifying renal sympathetic nerve activity includes a contact arrangement having a shape that generally conforms to a portion of a renal artery wall and is configured for placement at the renal artery wall portion. A compression arrangement is configured to cooperate with the contact arrangement to place the wall portion of the renal artery in compression sufficient to achieve a desired reduction in renal sympathetic nerve activity. The compression arrangement and the contact arrangement are preferably configured to cooperatively place the wall portion of the renal artery in compression sufficient to irreversibly terminate renal sympathetic nerve activity.

摘要： 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.

摘要： Devices and methods for creating a series of percutaneous myocardial revascularization (PMR) channels in the heart. One method includes forming a pattern of channels in the myocardium leading from healthy tissue to hibernating tissue. Suitable channel patterns include lines and arrays. One method includes anchoring a radiopaque marker to a position in the ventricle wall, then using fluoroscopy repeatedly to guide positioning of a cutting tip in the formation of multiple channels. Another method uses radiopaque material injected into each channel formed, as a marker. Yet another method utilizes an anchorable, rotatable cutting probe for channel formation about an anchor member, where the cutting probe can vary in radial distance from the anchor. Still another method utilizes a multiple wire radio frequency burning probe, for formation of multiple channels simultaneously. Still another method utilizes liquid nitrogen to cause localized tissue death.
