  • Patent number: 6503189
    Abstract: An anal incontinence disease treatment apparatus and method include and use an operable restriction device implanted in a patient and engaging the colon or engaging the rectum to form a restricted fecal passageway in the colon or rectum. A source of energy for energizing the restriction device is provided, as well as a control device for releasing energy from the source of energy from outside the patient's body. The released energy is used in connection with the operation of the restriction device, i.e. to enlarge and contract the fecal passageway to allow or substantially prevent passage of fecal material through the passageway.

  • Patent number: 6482145
    Abstract: An anal incontinence treatment apparatus and method includes and uses an adjustable restriction device implanted in a patient, who suffers from anal incontinence. The restriction device engages the rectum of the patient to restrict the fecal passageway. An adjustment device is adapted to adjust the restriction device such that the rectum is temporarily released, in order to open the fecal passageway when the patient wishes to achieve defaecation.

  • Patent number: 6475136
    Abstract: A heartburn and reflux disease treatment apparatus includes an adjustable restriction device implanted in a patient and engaging the stomach close to the cardia or engaging the esophagus to form a restricted food passageway in the stomach or esophagus. An adjustment device is implanted in the patient for adjusting the restriction device to restrict and enlarge the passageway and a hydraulic operation device is implanted in the patient for operating the adjustment device. By using a wireless remote control the patient can control the hydraulic operation device, whereby the restriction device works like an artificial sphincter.

  • Patent number: 6470892
    Abstract: A heartburn and reflux disease treatment apparatus includes an adjustable restriction device implanted in a patient and engaging the stomach close to the cardia or engaging the esophagus to form a restricted cross-sectional area of the food passageway in the stomach or esophagus, and a post-operation non-invasive adjustment device for mechanically adjusting the restriction device to change the cross-sectional area of the passageway. By using a wireless remote control the patient can control the adjustment device, whereby the restriction device works like an artificial sphincter.

  • Patent number: 6471635
    Abstract: A anal incontinence disease treatment apparatus and method include and use an operable restriction device implanted in a patient and engaging the colon or engaging the rectum to form a restricted fecal passageway in the colon or the rectum. A source of energy external to the patient's body and a control device for releasing wireless energy from the source of energy from outside the patient's body are provided. The released wireless energy is used in connection with the operation of the restriction device, to enlarge or contract the restricted fecal passageway.

  • Patent number: 6464628
    Abstract: An anal incontinence treatment apparatus includes an adjustable restriction device implanted in a patient, who suffers from anal incontinence. The device engages a portion of the colon or rectum of the patient to restrict the fecal passageway. An adjustment device mechanically adjusts the restriction device to restrict or release the fecal passageway, i.e., to normally close the fecal passageway and open the fecal passageway when the patient wants to relieve himself or herself.

  • Patent number: 6461292
    Abstract: An anal incontinence disease treatment apparatus and method include and use an operable restriction device implanted in a patient and engaging the colon or rectum to form a restricted. An energy transmission device for wireless transmission of energy of a first form from outside the patient's body is provided. An implanted energy transfer device transfers the energy of a first form transmitted by the energy transmission device into energy of a second form, which is used in connection with the operation of the restriction device, i.e. to open and close the fecal passageway.

  • Patent number: 6460543
    Abstract: A food intake restriction device for forming a stoma opening in the stomach or esophagus of a patient, comprises an elongated restriction member forming an expandable and contractible cavity formed into an at least substantially closed loop defining a restriction opening, the size of which is reduced upon expansion of the cavity and increased upon contraction of said cavity. A reservoir containing a predetermined amount of hydraulic fluid and connected to the cavity of the restriction member, and a hydraulic operation device for distributing fluid from the reservoir to the cavity to expand the cavity and for distributing fluid from the cavity to the reservoir to contract the cavity, are also implanted in a patient with morbid obesity and operated from outside the patient's body in a non-invasive manner. A non-inflatable restriction member may alternatively be use, and hydraulically adjusted.

  • Patent number: 6453907
    Abstract: A food intake restriction apparatus and method for an obese patient includes and uses an energy transmission device for wireless transmission of energy of a first form from outside the patient's body. An operable restriction device is implanted in the patient and engages the stomach or the esophagus to form an upper small pouch of the stomach, and a restricted stoma opening is formed in the stomach or esophagus. The restriction device is operable in response to a second energy form different than the first form to vary the restricted stoma. An energy transfer device is implanted in the patient for transferring energy of the first form transmitted by the energy transmission device into energy of the second form.
