Abstract: The invention relates to an artificial sphincter for controllably occluding a urine-carrying vessel of an incontinent patient, including a first electrically driven pump for pumping the hydraulic fluid against the force produced by the inherent elasticity of the reservoir from the hydraulic occlusion device to the elastic reservoir during normal operation, and a second emergency pump for pumping the hydraulic fluid against the force produced by the inherent elasticity of the reservoir from the occlusion device to the elastic reservoir during emergency operation, namely when said first pump does not function properly. The invention further relates to a method for controlling an artificial sphincter.

Abstract: According to one embodiment, a dialysis device is made available that can be implanted at least partially into the body of a patient and comprises a blood chamber, through which the patient's blood can flow, a dialysis chamber for receiving a dialysate, and a hydraulic pump device for compressing the two chambers alternately by means of a hydraulic fluid, wherein both chambers are each equipped with two valves for controlling the inflow and outflow of blood and dialysate, respectively, and wherein both chambers are connected to each other in an area designed as a membrane.

Abstract: A support device for supporting a transmission coil on the body of a patient, with a receiving or securing device or a receiving space for receiving or securing the transmission coil in and/or on the support device, and further comprising a detection device for detecting a process of application, a state of application, a process of removal and/or a state of removal of the support device relative to the body of the patient. Further pertaining to a method for operating such a device.

Abstract: A portable dialysis device that can be continuously worn in and/or on the body of a patient, with a blood chamber in which the patient's blood can be received, a hydraulic chamber which can be filled with a hydraulic fluid and which adjoins the blood chamber, an at least partially flexible delivery membrane which is arranged between the hydraulic chamber and the blood chamber and which, when the hydraulic chamber is filled with hydraulic fluid, is movable in the direction of the blood chamber in such a way as to cause a compression of the blood chamber and therefore an ejection of the blood located therein, a pump for controllable filling and/or emptying of the hydraulic fluid in the hydraulic chamber, such that blood can in this way be conveyed into the blood chamber and/or out of the latter, a filter membrane which is arranged between the blood chamber and the hydraulic chamber and through which waste substances in the blood can be removed to the hydraulic fluid located in the hydraulic chamber, such that t
