An injection port and implantable pump for adding fluid to, or withdrawing fluid from, a surgical implant inside a patient's body is disclosed. Also disclosed is a surgical method for treating diseases using the injection port and pump. The injection port and implantable pump includes a rigid base member and an injection membrane penetrable by an injection needle and attached to the base member. The membrane and base member define a chamber for holding fluid. The membrane is displaceable relative to the base member between a first position in which the volume of the fluid chamber is maximal and a second position, in which the volume of the chamber is minimal. According to the method, the membrane is manually displaced from time to time to distribute fluid between the fluid chamber of the injection port and the implant to operate the implant, which is typically a hydraulic restriction device. The implant can be designed for treating reflux disease, urinary incontinence, impotence, anal incontinence or obesity.
An injection port for adding fluid to or withdrawing fluid from a surgical implant inside a human body, the injection port comprising a rigid base member, and an injection membrane attached to said base member, said membrane and said base member defining a chamber for fluid, wherein said membrane includes a first layer and a second layer attached to each other, said first layer having better strength properties than said second layer and said second layer having better sealing properties than said first layer.
An implantable pump for pumping fluid to and from a surgical implant inside a human body, comprising a rigid base member, and an injection membrane penetrable by an injection needle and attached to said base member, said membrane and said base member defining a chamber for fluid, wherein said membrane is displaceable relative said base member between a first position, in which the volume of said chamber is maximal, and a second position, in which the volume of said chamber is minimal, whereby the amount of fluid that is to be pumped between said chamber and the surgical implant can be calibrated by inserting an injection needle through said injection membrane and adding fluid to or withdrawing fluid from said chamber.
A method for hydraulically operating a surgical implant implanted in a patient, the method comprising:
A surgical method for treating a patient having a disease, comprising the steps of:
