Abstract: A method for treating essential tremor or restless leg syndrome using spinal cord stimulation includes implanting a lead near a spinal cord of a patient. The lead includes a plurality of electrodes disposed on a distal end of the lead and electrically coupled to at least one contact terminal disposed on a proximal end of the lead. Electrical signals are provided from a control module coupled to the lead to stimulate a portion of the spinal cord of the patient using at least one of the electrodes. The electrical signals reduce, alleviate, or eliminate at least one adverse effect of essential tremor or restless leg syndrome.

Abstract: An extravascular pulsation blood pump possesses a bidirectionally acting pumping system (P, M) having a pump (P) which is connected via a first conduit (L1) to the left ventricle (LV) and via a second conduit (L2) to the aorta (AO). By means of a control means (St), the pump (P) is operated alternately in one and the other direction according to a given cardiac rhythm, so that alternately blood is sucked through the first conduit (L1) and simultaneously blood ejected through the second conduit (L2) to the same extent, on the one hand, and blood is sucked through the second conduit (L2) and simultaneously blood ejected through the first conduit (L1), on the other hand. The pulsation blood pump combines the functions and advantages of an extravascular copulsation pump with those of an extravascular counterpulsation blood pump.

Abstract: The invention is a next generation miniature heart assist device developed in order to maintain the blood circulation in patients with severe heart failure, and is applied endovascularly to the large arteries. This device is technically a kind of synchronous servo electric motor using “direct drive technology”. It provides longer battery life and high blood flow. Small volume and very low energy consumption provide a much longer battery life and a high blood flow. As the outer surface of the parts placed into the blood vessel will be completely covered with the endothelial cells and the intima layer of the arteries in time, there will be no foreign surface contacting directly with blood. As a result, no thromboembolic event or any negative effect on the cellular components of blood is expected.

Abstract: The present disclosure involves a method of measuring a physiological feedback from a patient in response to electrical stimulation. A stimulation parameter of a sacral nerve stimulation therapy is ramped up. The sacral nerve stimulation therapy includes electrical pulses generated by a pulse generator based on programming instructions received from an electronic programmer. The electrical pulses are delivered to a patient via a stimulation lead that is implanted in the patient. Via an anal electrode device that is at least partially inserted inside an anal canal of the patient, a compound motor action potential (CMAP) is measured from an anal sphincter of the patient while the stimulation parameter of the sacral nerve stimulation therapy is being ramped up. A stimulation threshold is determined based on the measured CMAP.

Abstract: In some examples, relatively low frequency (e.g., less than about 50 Hertz) electrical stimulation therapy is delivered to a target tissue site proximate to one or more of the T9, T10, T11, T12, L1, L2, or L3 (“T9-L3”) spinal nerves of a patient to manage a pelvic floor disorder, such as urinary retention, fecal retention, or both. The relatively low frequency electrical stimulation therapy is configured to excite the one or more of the T9-L3 spinal nerves, which may generate an activating response from the patient related to voiding and help promote voiding by the patient. For example, the low frequency electrical stimulation may be configured to help improve the patient's pelvic sensations, which may help the patient better control urination.
