Restriction device

A hydraulic implantable restriction device for restricting a luminary organ of a patient, the hydraulic implantable restriction device comprising:

• a first hydraulic elongated restriction element and forming means for forming the elongated restriction member into at least a substantially closed loop around a first portion of the luminary organ, the first elongated restriction element being adapted to restrict the first portion of the luminary organ, and
• a second hydraulic elongated restriction element and forming means for forming the elongated restriction member into at least a substantially closed loop around a second portion of the luminary organ, the second elongated restriction element adapted to restrict the second portion of the luminary organ, and
• a hydraulic pump, for pumping fluid from an implantable reservoir to at least one of the first and second restriction elements, the hydraulic pump comprising a hollow member for fluid transportation, and an operable compression member adapted to engage and compress the hollow member, the hydraulic pump being arranged for, upon compression of the hollow member, pumping fluid from one of the first and second restriction elements, via the hollow member, to the other one of the first and second restriction elements, such that operation of the hydraulic pump in a first operational state simultaneously causes the first hydraulic restriction element to restrict the first portion of the luminary organ and the second hydraulic restriction element to release the restriction of the second portion of the luminary organ, and in a second operational state simultaneously causes the first hydraulic restriction element to release the restriction of tile first portion of the luminary organ and the second hydraulic restriction element to restrict the second portion of the luminary organ, and
• a control unit adapted to control the hydraulic pump and to control the first and second restriction elements for automatically switching between restricting the first and second portion of the luminary organ, for creating a less damaging restriction, wherein the control unit is adapted to automatically switch between restricting the first and second portion of the luminary organ on a basis of at least one of:
• a lapsed time being between 10 minutes and 6 months, and
• the patient using a function of the restricted luminary organ.
