Implantable penile prosthesis fluid transfer systems and methods
View Patent ↗Surgical implants and procedures for restoring erectile function are described. One method includes the steps of providing an inflatable prosthesis system with a pump, a cylinder, a septum, and a reservoir, the system having sufficient fluid to inflate the cylinder and reservoir, implanting the system in an inflated condition and leaving the system in this condition in the post-operative period, then inserting a needle through the septum and withdrawing some fluid from the system. The systems of the invention may include the insertion of a needle through the septum for the injection of an antimicrobial or antibiotic.
1. A method of restoring erectile function comprising the steps of:
providing an inflatable penile prosthesis system comprising a pump, a cylinder capable of inflated and deflated states, a septum and a reservoir capable of inflated and deflated states;
providing sufficient fluid to inflate the cylinder and the reservoir to the inflated condition;
implanting the inflatable penile prosthesis system with the cylinder and reservoir in the inflated condition;
leaving the cylinder and reservoir in the inflated condition in the immediate post operative period, and
thereafter inserting a needle through the septum and withdrawing some fluid from the inflatable penile prosthesis system.
2. A method according to claim 1 wherein the step of leaving the cylinder and reservoir in the inflated condition in the immediate post operative period includes the step of leaving the cylinder and reservoir in the inflated condition for at least three days.
3. A system for restoring erectile function comprising:
a pump, a cylinder, tubing and a reservoir,
a fluid circuit within the system containing fluid,
a septum, and
an antimicrobial within the fluid placed by inserting a needle through the septum and injecting the antimicrobial.
4. A system for restoring erectile function according to claim 3 wherein the antimicrobial comprises rifampin and minocycline.
5. A system for restoring erectile function according to claim 3 wherein the antimicrobial comprises an iodine containing compound.
6. A method of restoring erectile function comprising the steps of:
implanting an inflatable penile prosthesis having fluid and a septum,
placing a needle through the septum, and
providing an antimicrobial solution through the septum and into the prosthesis.
7. A method according to claim 6 wherein the prosthesis comprises a cylinder comprising silicone, and
the antimicrobial solution comprises iodine.
8. A method according to claim 6 further including the step of aspirating fluid from the inflatable penile prosthesis prior to the step of providing an antimicrobial solution.
9. A method according to claim 6 wherein the step of providing an antimicrobial solution into the prosthesis further comprises inflating the prosthesis and wherein the method further comprises the subsequent step of deflating the prosthesis by accelerated osmosis of the antimicrobial solution through the prosthesis.
10. A method according to claim 9 wherein the step of implanting a prosthesis includes the step of implanting a prosthesis constructed at least in part of silicone and the antimicrobial solution comprises iodine.
11. A method according to claim 6 wherein the step of providing the antimicrobial solution comprises injecting the antimicrobial solution.
