Abstract: A thrombectomy system may include an elongate shaft that defines a high pressure lumen and a low pressure lumen. The high pressure lumen may terminate near an end of the low pressure lumen. An expandable capture basket may be disposed near the end of the low pressure lumen. A thrombectomy apparatus may include an elongate shaft, an evacuation lumen extending within the elongate shaft and a high pressure lumen extending within the elongate shaft. A capture apparatus may be disposed within a wire lumen that extends within the elongate shaft such that the capture apparatus extends distally from the wire lumen.

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.

Abstract: An apparatus for locally controlling smooth muscle tone includes a first electrode for insertion into an artery; a barrier for preventing the first electrode from contacting an arterial wall; a second electrode; a power supply; and a controller for coupling the power supply to the electrodes. The controller is configured to cause the electrode to maintain a waveform for controlling polarization of smooth muscle tone.
