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 breast implant system is provided comprising a plurality of chambers including one or more first fluid chambers (1) and one or more second fluid chambers (2). The first fluid chamber (1) forms part of a breast implant (10), whereas the second fluid chamber (2) may also form part of the breast implant or may be implanted remote from the breast implant. The first and second fluid chambers are interconnected so as to allow exchange of fluid between the first and second chambers, thereby causing the shape and, depending upon the specific embodiment, also the volume to change accordingly.

Abstract: A medical device for implantation in a hip joint of a patient is provided. The medical device comprises a first and second piece and a releasing member adapted to, in a first state hold the first piece attached to the second piece, and in a second state release the first piece from the second piece. The releasing member is adapted to change from the first state to the second state when a pre-determined strain is placed on the releasing member.

Abstract: A hip joint prosthesis adapted to be implanted in a hip joint of a human patient is provided. The hip joint prosthesis comprises a first area and a second area, and wherein said first area comprises a first material adapted to be elastic and said second area comprises a second material adapted to be elastic, and wherein said first material is adapted to be more elastic than said second material.

Abstract: A medical device for implantation in a hip joint of a patient is provided. The medical device is adapted to be fixated to the pelvic bone of the patient. The medical device comprises an inner and an outer surface, wherein a contacting portion, of said inner surface is spherical and adapted to face the center of the hip joint when said medical device is implanted. The medical device is adapted to receive a caput femur or a prosthetic replacement therefor having a spherical portion, wherein said medical device comprises at least one extending portion, extending said contacting portion of said inner surface such that said at least one extending portion clasps said spherical portion of said caput femur, or a prosthetic replacement therefor, such that said spherical portion is restrained in said medical device. Restraining the caput femur in the medical device reduces the risk that the hip joint dislocates when in use by the patient.

Abstract: The invention discloses an ostomy accessory (20) for an intestinal stoma of a mammal ostomy patient, adapted to be used together with an implanted constriction device with an artificial closing sphincter function for closing the intestinal passageway. The ostomy accessory is adapted to absorb secret from the mucosa wall of the part of the intestine which is distal to the constriction device, which may secrete or disseminate some liquid matter, which may thus spill out and cause discomfort to the patient, for example by staining the clothes of the patient. The ostomy accessory comprises an insertion portion (21) for insertion into said intestinal stoma and comprising an absorbing body (23, 24, 25) for absorbing and retaining liquid matter consisting of liquid secreted from a mucosa wall of the intestine (31).

Abstract: In supplying energy to a medical device implanted in a mammal patient a first coil system (20) external to the patient's body for wirelessly transferring energy can be used that inductively cooperates with a second coil system (12) that, when implanted in the patient's body, receives wirelessly transferred energy for supplying energy or control signals to the medical device, when implanted in the patient's body. The first and second coil systems comprise each at least two individual coils (50, 51; 60, 61) which are not directly electrically connected to each other and operate basically independently of each other. This may give a very efficient and versatile transfer of energy or control signals. The coils in each of the coil systems can be operating at different frequencies by being connected to respective electric circuits, where each of these respective electric circuits operate basically independently of each other generating e.g. alternating electric current of different frequencies.
