Definitions
- the membrane may comprise a third layer harder than the second layer, wherein the third layer is situated between the second layer and the chamber.
- the silicone membrane is mounted under tension, which makes it possible to inject a specific type of hypodermic needle into the fluid chamber of the pump, without causing leakage through the membrane after the needle has been removed from the membrane.
- This type of hypodermic needle has a lateral opening and does not cut out any remaining hole in the silicone membrane. The needle just moves the silicone material aside.
- the surgical implant comprises a hydraulic constriction device for constricting a passageway of an organ of a human or an animal.
- the constriction device may be used for constricting the stomach of an obese patient to restrict the patient's food intake, for constricting the esophagus of a patient who suffers from reflux disease, or for restricting the exit penile blood of an impotent patient.
- the constriction device may be used as an artificial sphincter in an anal or urinary incontinent patient.
- the apparatus of the invention includes a control device, for example a microprocessor, for controlling the pump assembly.
- the control device includes a remote control, conveniently a wireless remote control, for controlling the pump assembly from outside the patient's body.
- the wireless remote control may include at least one external signal transmitter or transceiver and at least one internal signal receiver or transceiver implantable in the patient.
- the wireless remote control may be adapted to transmit at least one wireless control signal, which may be a frequency, amplitude or frequency or amplitude modulated signal.
- the control signal may be an analog or a digital signal, or a combination of an analog and digital signal and the remote control may transmit an electromagnetic carrier wave signal for carrying the digital or analog control signal.
- the pump assembly may be used for distributing liquid from one part to another part of a human body.
- the apparatus of the invention may also be used in connection with hydraulically controlled implants to distribute liquid within the hydraulic implant or to distribute liquid to and from an implanted liquid reservoir of the implant.
- hydraulically controlled implants are artificial spincters for occluding a body opening for treating anal incontinence, colostomy, ileostomy, jejunostomy, urine incontinence, or hernia in the cardia region.
- Another example is a hydraulic constriction device for forming a stoma opening in any part of the body for example in the stomach or esophagus of an obese patient to treat obesity.
- Figure 8 shows an alternative design of the embodiment shown in Figure 5
- Figure 9 shows another embodiment of the apparatus of the invention with a motor-driven pump.
- Figure 1 shows an implantable pump 1 according to the present invention including a wall 2 forming a chamber 3 for hydraulic fluid, typically an isotonic salt solution.
- a nipple 3A for connection to a tube (not shown) for distributing hydraulic fluid from chamber 3 is provided.
- the wall 2 includes a first wall portion in the form of a rigid base plate 4 and a second wall portion in the form of a relatively thin flexible injection membrane 5, which takes the shape of a semi-sphere and is attached to base plate 4.
- the injection membrane 5 enables calibration of the pumpable amount of hydraulic fluid by injecting a hypodermic needle through the membrane 5 and adding hydraulic fluid to or withdrawing hydraulic fluid from chamber 3.
- the amount of fluid in the fluid distribution system of the apparatus can be calibrated by penetrating membrane 5 of pump 1 with a needle 17 of a syringe 18 and adding hydraulic fluid to or withdrawing hydraulic fluid from chamber 3 of pump 1.
- the apparatus shown in Figure 4 may also be used for treating patients suffering from heartburn and reflux disease, obesity or anal incontinence, or for temporarily restricting the penile exit blood flow of an impotent patient.
- displaceable injection membrane 5 is used to manually pump hydraulic fluid between fluid chamber 3 and implanted constriction device 14.
- the total amount of hydraulic fluid in fluid chamber 3, tube 15 and cavity 16 is calibrated by penetrating the patient's skin and membrane 5 with injection needle 17 of syringe 18 to add or withdraw fluid from chamber 5.
- Membrane 5 is manually displaced from time to time to pump the fluid to or from chamber 3 of pump 1 to operate constriction device 14.
- FIG. 5 schematically shows another embodiment of the apparatus of the invention, which is similar to the embodiment shown in Figure 4, except that the constriction device is designed differently.
- the apparatus according to Figure 5 has a constriction device 19 including a relatively small inflatable cavity 20, which is in fluid communication with chamber 3 of pump 1, and a relatively large cavity 21, which is displaceable by small cavity 20.
- Small cavity 20 is adapted to displace large cavity 21 to constrict the passageway when small cavity 20 is inflated and to displace large cavity 21 to release the passageway when small cavity 20 is deflated.
- a relatively small addition of hydraulic fluid from pump 1 to small cavity 20 causes a relatively large increase in the constriction of the passageway in question.
- FIG 8 shows an alternative design of the apparatus shown in Figure 5.
- injection port 23 is substantially smaller than pump 1 and is attached to nipple 3A of pump 1.
