The present invention relates to a male contraception apparatus for obtaining temporary sterility of a male mammalian individual. The apparatus has an implantable restriction device adapted to restrict vas deference in the region downstream the ampulla during a controlled period in order to preventing sperms to reach the urethra. Further, the apparatus has a control device for controlling the operation of the restriction device.

A medical device has an artificial contractile structure including at least one contractile element adapted to contract a hollow body organ in such a way that said contractile element is adapted to be in a resting position or in an activated position, the activated position being defined with the contractile element constricting the hollow body organ and the resting position being defined with the contractile element not constricting the hollow body organ. The medical device further includes a tensioning device adapted to apply a force so as to tighten the contractile element around the hollow body organ. The medical device further includes a means for eliminating a dead zone of the contractile element when the contractile element is attached around hollow organ with a circumference of the contractile element less than a maximum possible circumference.

A medical device has an artificial contractile structure including at least one contractile element adapted to contract a hollow body organ in such a way that said contractile element is adapted to be in a resting position or in an activated position, the activated position being defined with the contractile element constricting the hollow body organ and the resting position being defined with the contractile element not constricting the hollow body organ. The medical device further includes a tensioning device adapted to apply a force so as to tighten the contractile element around the hollow body organ. The contractile element further includes a closure for forming the contractile element into a closed loop around said hollow body organ, the closure having a plurality of lips arranged to engage the contractile element.

A medical device has an artificial contractile structure including at least one contractile element adapted to contract a hollow body organ in such a way that said contractile element is adapted to be in a resting position or in an activated position, the activated position being defined with the contractile element constricting the hollow body organ and the resting position being defined with the contractile element not constricting the hollow body organ. The medical device further includes a tensioning device adapted to apply a force so as to tighten the contractile element around the hollow body organ, the tensioning device having a flexible transmission with a tensioning element arranged in a sheath. The sheath has an inner coiled wire coiled in a first direction, and an outer coiled wire surrounding the inner coiled wire and coiled in a second direction opposite to said first direction.

An implantable device to treat obesity and a method of using the same, the device (31) is able to create a repetitive mechanical constraint on a gastrointestinal organ wall and includes: an energy source (36), and a mechanical stimulation element (35).

Medical device including an artificial contractile structure including at least one contractile element adapted to contract a hollow body organ, in such a way that the contractile element is adapted to be in a resting position or in an activated position, the activated position being defined with the contractile element constricting the hollow body organ and the resting position being defined with said contractile element not constricting the hollow body organ. The medical device can include a tensioning device adapted to apply a force so as to tighten the contractile element around said hollow body organ. The tensioning device can be arranged to cause the contractile element to apply a substantially uniform occlusive pressure of at most 8N/cm.sup.2, along the circumference of the contact area between the contractile element and the hollow body organ when the contractile element is in its activated position.

A male contraception apparatus for obtaining temporary sterility of a male mammalian individual is provided. The apparatus comprising an implantable restriction device adapted to restrict vas deference in the region downstream the ampulla during a controlled period, said device thereby being capable of preventing sperms to reach the urethra, a control device for controlling the operation of the restriction device, and at least one implantable sensor adapted to send a measurement or an indication of the measurement to the control device.

A medical device for narrowing or closing an anatomical channel includes a band part (1) which can be placed around the body tissue (2) surrounding the anatomical channel and which can be closed to form a ring that encloses a through-opening (6) for the body tissue, wherein the band part (1) has a hollow chamber (3), and wherein the through-opening (6) can be made smaller by introducing a fluid into the hollow chamber (3). The medical device moreover includes a pump unit (10) which serves to convey the fluid and which has an electric drive (15) controllable by an electronic control system of the device, wherein a pressure value corresponding to the pressure of the fluid in the hollow chamber (3) or dependent on this pressure can be detected by the electronic control system. The device moreover has an air pressure sensor (23) for detecting the atmospheric pressure.

A system includes an adjustable implant configured for implantation internally within a subject and includes a permanent magnet configured for rotation about an axis of rotation, the permanent magnet operatively coupled to a drive transmission configured to alter a dimension of the adjustable implant. The system includes an external adjustment device configured for placement on or adjacent to the skin of the subject having at least one magnet configured for rotation, the external adjustment device further comprising a motor configured to rotate the at least one magnet and an encoder. Rotation of the at least one magnet of the external adjustment device effectuates rotational movement of the permanent magnet of the adjustable implant and alters the dimension of the adjustable implant. Drive control circuitry is configured to receive an input signal from the encoder.

The present disclosure relates to treatment of reflux disease of a human patient. More particularly, a device is disclosed, which is configured to be implanted in the body of the human to restrict movement of the cardia of the patient's stomach towards the diaphragm opening into the patient's thorax, and/or to prevent stomach contents from passing from the stomach into the esophagus.
