Abstract

A method of implanting a penis erection stimulation system into a patient's body comprises cutting the skin of the patient body, dissecting free an area near the left and right corpus cavernosum, placing a drug delivery device within the dissected area and placing at least one infusion needle of the drug delivery device in a first position in the patient's body in between the left and right corpus cavernosum.

First claim

The invention claimed is:

1. A method of implanting a penis erection stimulation system in a patient's body, comprising a fully implantable drug delivery device adapted to deliver a drug in relation to a penis to achieve erection of the penis, wherein the drug delivery device comprises at least one infusion needle adapted to be placed outside a left or a right corpus cavernosum in close proximity thereto, wherein the fully implantable drug delivery device is adapted to be non-invasively powered, when implanted, wherein the infusion needle is adapted to be advanced into and retracted from, as well as deliver at least one drug when advanced into, at least one of: the left or right corpus cavernosum, one or two of deep arteries thereof, muscle tissue regulating blood flow through the right, left or both corpus cavernosum, and tissue in close proximity to the left, right or both corpus cavernosum, and whenever the needle is or has been advanced, when the drug delivery device is implanted, the at least one infusion needle is further configured to fit in a position in between the left and right corpus cavernosum at a base of penile tissue placed inside the patient's body where the left and right corpus cavernosum are deviating away from each other, and wherein the method comprises the step of:
cutting skin of the patient's body,
dissecting free an area near the left and right corpus cavernosum,
placing the drug delivery device within said dissected area arranged next to at least one of: the left and right corpus cavernosum, the two deep arteries of the right and left corpus cavernosum, the muscle tissue regulating blood flow through the left and right corpus cavernosum and another kind of tissue in close proximity to the left and right corpus cavernosum, so as to allow for stimulation of the penis erection by delivering the drug, and
placing the at least one infusion needle in a first position in the patient's body in between the left and right corpus cavernosum at the base of the penile tissue placed inside the patient's body where the left and right corpus cavernosum are deviating away from each other.

2. The method of claim 1 , comprising the steps of:
implanting at least one housing having an outer wall and including the at least one infusion needle arranged for allowing to penetrate the at least one housing's outer wall in said first position, and
implanting placed in the housing at least one drive unit arranged at least for advancing and retracting a tip end of the at least one infusion needle so that postoperatively the at least one infusion needle is able to penetrate said at least one housing's outer wall upon advancement of the tip end or ends thereof, allowing for postoperative stimulation of the penis erection by injecting the at least one drug through the at least one infusion needle on patient command.

3. The method of claim 2 , comprising the step of penetrating the infusion needle through the housing's outer wall, into at least one of the left and right corpus cavernosum, the muscle tissue regulating blood flow through at least one of the left and right corpus cavernosum and into the another kind of tissue in close proximity to the left and right corpus cavernosum.

4. The method of claim 2 , comprising the step of securing the corpus cavernosum to the housing by means of a holder connected to the housing.

5. The method of claim 2 , wherein the drive unit is configured to at least postoperatively laterally displace a tip end of at least one of said at least one infusion needle in at least two different lateral directions to different penetration sites within at least one penetration area, and wherein the at least one infusion needle is arranged for penetrating the at least one housing's outer wall at said different penetration sites in said at least one penetration area.

6. The method of claim 5 , further comprising penetrating the at least one housing's outer wall, during operation or postoperatively, by the at least one infusion needle at said at least two different penetration sites, in said at least one penetration area in accordance with at least one of, upon a single command or single action: simultaneously both penetration areas, and both penetration areas in immediate time succession.

7. The method of claim 2 , wherein the step of implanting the infusion needle comprises the step of implanting the at least one infusion needle being flexibly bendable, wherein the tip end of each of the at least one infusion needle is arranged for penetrating the outer wall of a first one of the at least one housing and the other end thereof is arranged in a second one of said at least one housing for remote implantation inside the patient's body, the method further comprising the step of implanting the flexibly bendable injection needle being sufficiently long to bridge a distance from the second housing for remote implantation to the first housing and further through the first housing up to the outer wall of the first housing.

8. The method of claim 2 , comprising the step of: providing energy by an energy source to at least one of: a pump, the at least one drive unit, a motor and any other energy consuming part of the system, wherein the energy source comprises at least one of: an internal power supply for implantation within the housing implanted in the patient's body, an internal power supply for implantation remote from the housing accommodating the infusion needle implanted in the patient's body, an external power supply adapted to wirelessly transfer energy, and an external power supply for charging an internal power supply from outside the patient's body.

9. The method of claim 1 , comprising the further steps of:
implanting at least one housing having an outer wall and including the at least one infusion needle arranged for allowing to penetrate the at least one housing's outer wall in said first position,
dissecting a second area remote from the first area and placing at least one reservoir in the patient's body in the remote second area,
connecting the reservoir, using a conduit, with the at least one infusion needle accommodated in the at least one housing.

10. The method of claim 9 , comprising the step of placing the reservoir adjacent to a symphyseal bone or pelvic bone of the patient's body.

11. The method of claim 9 , further comprising the steps of placing an injection port for refilling the reservoir, allowing the later step of replenishing the implanted reservoir by penetrating a replenishing needle through the injection port and injecting a substance through the replenishing needle directly or indirectly into the reservoir, wherein at least in the penetration area or areas the at least one housing's outer wall is made from a material which is self-sealing in respect of penetrations resulting from said at least one infusion needle, wherein the self-sealing material comprises a penetration membrane integrated in the at least one housing's outer wall by being sealingly press-fitted into the at least one housing's outer wall, wherein the at least one infusion needle has a tube-like body closed at the tip end and having a laterally arranged delivery exit port.

12. The method of claim 1 , further comprising the step of placing one or more of the following elements within the patient's body:
at least part of a drive unit, and
at least one motor for actuation of at least one of: the drive unit, a drive driving the drive unit, a pump, and any other energy consuming part of the system.

13. The method of claim 12 , further comprising the steps of placing one or more of the following elements within the patient's body:
an implantable energy storage for
