Inflatable medical implant system
A medical implant system for implantation in a patient to treat erectile dysfunction includes a first fluid path, an inflatable penile prosthesis cylinder, an electric pump, and implant controller, and an implantable power supply. The inflatable penile prosthesis cylinder is in fluid communication with the first fluid path and is configured for implantation in a corpus cavernosum of a patient. The electric pump is in fluid communication with the first fluid path. The implant controller is electrically coupled to the pump and is configured to activate the pump to drive a flow of fluid through the first fluid path and into the cylinder. The implantable power supply provides electrical power to the pump.
1. An apparatus comprising:
an inflatable implant;
a fluid reservoir fluidically coupled to the inflatable implant via a first fluid path;
a pump fluidically coupled to the fluid reservoir via a second fluid path, the pump being fluidically coupled to the inflatable implant via a third fluid path,
wherein fluid is configured to flow from the fluid reservoir to the inflatable implant via the first fluid path when the apparatus is in a filling state,
wherein fluid is configured to flow from the inflatable implant to the pump via the third fluid path and from the pump to the fluid reservoir via the second fluid path when the apparatus is in an emptying state;
a valve disposed within the second fluid path between the pump and the fluid reservoir, the valve having an open state and a closed state, wherein, when the valve is in the closed state, fluid is blocked from being transferred between the pump and the fluid reservoir;
a controller operatively coupled to the pump to selectively activate the pump and selectively actuate the valve between the open state and the closed state; and
a sensor configured to sense one of a current and a voltage supplied to the pump and output a pressure feedback signal that is indicative of a pressure of the inflatable implant.
2. The apparatus of claim 1 , wherein the valve is a first valve, the apparatus further comprising:
a second valve disposed within the first fluid path between the fluid reservoir and the inflatable implant.
3. The apparatus of claim 1 , further comprising:
a power supply operatively coupled to the controller.
4. The apparatus of claim 1 , wherein the inflatable implant is selected from the group consisting of an inflatable cuff and a penile prosthesis.
5. The apparatus of claim 1 , wherein the first fluid path includes tubing, the second fluid path includes tubing, and the third fluid path includes tubing.
6. An apparatus comprising:
an inflatable implant;
a fluid reservoir fluidically coupled to the inflatable implant via a first fluid path;
a pump fluidically coupled to the fluid reservoir via a second fluid path, the pump being fluidically coupled to the inflatable implant via a third fluid path;
a valve disposed within the second fluid path between the pump and the fluid reservoir,
wherein fluid is configured to flow from the fluid reservoir to the pump via the second fluid path and from the pump to the inflatable implant via the third fluid path when the apparatus is in a filling state,
wherein fluid is configured to flow from the inflatable implant to the fluid reservoir via the first fluid path when the apparatus is in an emptying state; and
a sensor configured to sense one of a current and a voltage supplied to the pump and output a pressure feedback signal that is indicative of a pressure of the inflatable implant.
7. The apparatus of claim 6 , wherein the valve is a first valve, the apparatus further comprising:
a second valve disposed within the first fluid path between the fluid reservoir and the inflatable implant.
8. The apparatus of claim 6 , further comprising:
a controller operatively coupled to the pump to selectively activate the pump.
9. The apparatus of claim 6 , further comprising:
a controller operatively coupled to the pump; and
a power supply operatively coupled to the controller.
10. The apparatus of claim 6 , wherein the inflatable implant is selected from the group consisting of an inflatable cuff and a penile prosthesis.
11. The apparatus of claim 6 , wherein the first fluid path includes tubing, the second fluid path includes tubing, and the third fluid path includes tubing.
12. A method, comprising:
inserting a device into a body of a patient, the device including an inflatable implant, a fluid reservoir fluidically coupled to the inflatable implant via a first fluid path, and a pump fluidically coupled to the fluid reservoir via a second fluid path, the pump being fluidically coupled to the inflatable implant via a third fluid path, the device including a valve disposed within the second fluid path between the pump and the fluid reservoir;
inflating the inflatable implant by conveying fluid from the fluid reservoir to the inflatable implant via the first fluid path;
opening the valve disposed within the second fluid path; and
deflating the inflatable implant by conveying fluid from the inflatable implant to the pump via the third fluid path and from the pump to the fluid reservoir via the second fluid path.
13. The method of claim 12 , wherein the inserting includes inserting the device into a pelvic region of the patient.
