Abstract: A male sexual impotence treatment apparatus comprises an adjustable non-inflatable restriction device implanted in a male impotent patient. The restriction device directly engages a portion of the normal penile tissue of the patient, such as both of the corpora cavernosa as a single unit or one or more of the exit veins from the penis, to affect the blood flow leaving the penis. An adjustment device mechanically adjusts the restriction device to temporarily restrict the blood flow leaving the penis when the patient wishes to achieve erection.

Abstract: The disclosed invention varies the width of the energy pulses with constant frequency and constant amplitude to regulate the amount of energy transferred from an energy transmitting device placed outside a patient to an energy receiver inside the patient. The pulse width is achieved with a modulation technique, PWMT, to control the amount of energy transferred from the external energy transmitting coil in the system to the implanted receiver. The PWMT is used to digitally vary the amount of power from the power amplifier that drives the transmitting coil. Compared to previous analog systems a PWM system is a great deal more efficient and can easily be controlled from a digital domain system such as a microprocessor.

Abstract: A therapeutic brain stimulation system comprises at least two stimulation signal emitters generating stimulation signals from different positions towards a common target region in a patient's brain. While the signal intensity of each stimulation signal is much too low to cause stimulation, the accumulated stimulation signals cause a stimulation and, thus, a therapeutic effect in the neuronal brain cells of the target region. The stimulation signals accumulating in the target region are adjustable so as not to negatively affect the anatomic structure of neuronal brain cells in the target region.

Abstract: A device for treating obesity of a patient, the device comprising: at least one operable stretching device implantable in the patient and adapted to stretch a portion of the patient's stomach wall, and an implantable control unit for automatically controlling the operable stretching device, when the control unit and stretching device are implanted, to stretch the stomach wall portion in connection with the patient eating such that satiety is created.

Abstract: A system is disclosed which comprises an implantable electrical medical device (100) with an internal energy receiver (102). The system also comprises an external energy source (104) located externally for supplying wireless energy to the internal energy receiver (102). The external energy source (104) has a primary coil (11) for transmitting energy inductively to a first secondary coil (10) in the energy receiver (102). The system is arranged to measure parameters related to a first coupling factor (C1) between the primary and the first secondary coil (10), and the external energy source (104) is adapted to transmit energy to the energy receiver (102) for enabling the medical device (100) to detect information related to the first coupling factor (C1).

Abstract: Where an implanted reservoir (140) for intestinal contents is formed from surgically modified intestine (70) that has been cut along a mutual contact line of laterally adjacent sections of a bent portion of intestine and connected so that the resulting upper and lower halves of the intestine form an intestinal wall of the reservoir, the system for emptying such intestinal reservoir comprises an artificial flow body and adapted to control flow of the intestinal reservoir comprises an artificial flow control device (160) implantable in the patient's body and adapted to control flow of the intestinal contents from said reservoir, the flow control device comprising at least one pump adapted to act on said intestinal wall so as to reduce the reservoir's volume, thereby emptying the reservoir. The system may further comprise an entry valve upstream of the reservoir and an exit valve downstream from the reservoir.

Abstract: An implantable device for improving the pump function of the heart of a human patient by applying an external force on the heart muscle is provided.

Abstract: A proposed treatment of arthrosis/osteoarthritis in a joint of a mammal or human patient involves deposing a liquid material on at least one damaged surface of the joint. To accomplish this, a reservoir (110) is provided, which holds a volume of a biocompatible material in liquid form outside of a body containing the joint (J) to be treated. A proximal end (P) of a tube-shaped instrument (120) is connected to the reservoir (110), and a distal end (D) of the instrument (120) is inserted into the joint (J). The liquid material is fed through the instrument (120) to the distal end (D) for deposition on the at least one damaged joint surface. The material is configured to assume a solid form under predefined conditions (e.g. when cooling off or being exposed to a specific type of radiation). When the material has the solid form, it has a resistance to wear adapted to replace a worn out joint surface.
