Abstract
An apparatus for distributing a liquid in a patient's body comprises an implantable pump adapted to pump the liquid and an implantable valve device adapted to direct the liquid pumped by the pump. A first ceramic valve member of the valve device includes a first plane surface and a second ceramic valve member of the valve device includes a second plane surface facing and touching the first plane surface. The second valve member is displaceable relative to the first valve member between different positions, wherein the valve members include different liquid channels. The valve device is operable to displace the second valve member to hydraulically connect the pump to at least one of the liquid channels in at least one of the positions.
Claims139
A implantable valve device, comprising:
- a first valve member including a first plane surface, and
- a second valve member including a second plane surface facing and touching said first plane surface, said second valve member being displaceable relative to said first valve member between different positions while said second plane surface touches said first plane surface, said first and second plane surfaces of said valve members having a smoothness such that they form a liquid seal as they touch each other,
- said valve members including different liquid channels and said second valve member is adapted to connect at least two of said different channels to each other when said second valve member is in at least one of said positions, the implantable valve device being implantable in human or animal body.
An implantable apparatus for distributing a liquid in a patient's body, comprising:
- a pump adapted to be implanted in the patient to pump the liquid,
- an implantable valve device adapted to direct the liquid pumped by said pump,
- a first valve member of said valve device including a first plane surface, and
- a second valve member of said valve device including a second plane surface facing and touching said first plane surface, said second valve member being displaceable relative to said first valve member between different positions while said second plane surface touches said first plane surface, said first and second plane surfaces of said valve members having a smoothness such that they form a liquid seal as they touch each other,
- said valve members including different liquid channels, and said valve device is operable to displace said second valve member to hydraulically connect said pump to at least one of said liquid channels when said second valve member is in at least one of said positions.
