Abstract

A penis erection stimulation system comprises one or more infusion needles disposed within and implanted along with one or more housings adjacent the patient'"'"'s left and right corpora cavernosa. A reservoir and a pump are also implanted inside the patient'"'"'s body to supply the infusion needle with infusion liquid. A drive unit also adapted for implantation inside the patient'"'"'s body is arranged for advancing and retracting the tip end of the infusion needle such that it penetrates the housing at least in two different penetration areas either simultaneously or in immediate time succession, thereby injecting drugs along with the infusion liquid into the patient'"'"'s body for stimulating penis erection. The drive unit is configured to laterally displace the tip end of at least one infusion needle in at least two different lateral directions to different penetration sites within said at least one penetration area.

Claims

1. A penis erection stimulation system, comprising at least one infusion needle (11) disposed at least partly within at least one housing (12) with a tip end (13) of the at least one infusion needle arranged for penetrating the at least one housing'"'"'s outer wall (15), the at least one housing being adapted for implantation inside a patient'"'"'s body, at least one reservoir (R1, R2) adapted for implantation inside the patient'"'"'s body in fluid connection with the at least one infusion needle to supply to the infusion needle a substance to be injected into the patient'"'"'s body, —

at least one pump (P) adapted for implantation inside the patient'"'"'s body to advance the substance from the reservoir to the at least one infusion needle, and at least one drive unit (D) adapted for implantation inside the patient'"'"'s body, the at least one drive unit being coupled to the at least one infusion needle and arranged for advancing and retracting the tip end of the at least one infusion needle so that the at least one infusion needle penetrates, upon advancement of the tip end or ends thereof, said outer wall in at least one penetration area (14) so as to allow for stimulation of penis erection by injecting the substance through said at least one penetration area via the at least one infusion needle, wherein the drive unit is configured to laterally displace the tip end of at least one of said at least one infusion needle in at least two different lateral directions.

Self-Sealing Material

2. The system of claim 1, wherein at least in the penetration area or areas the outer wall is made from a material which is self-sealing in respect of penetrations resulting from said at least one infusion needle.

3. The system of claim 2, wherein the self-sealing material forms at least two window areas in said outer wall, said window areas being positioned for penetration by the tip end of the at least one infusion needle.

4. The system of either of claim 2, wherein the self-sealing material comprises a penetration membrane integrated in the outer wall by being sealingly press-fitted into the outer wall.

5. The system of any of claim 2, wherein the self-sealing material comprises at least one polymer selected from the group of materials comprising silicon and polyurethane.

9. The system of claim 1, wherein the outer wall comprises at least one flap in the penetration area or areas through which the at least one infusion needle can pass, said flap being arranged to be pushed aside by the at least one infusion needle upon advancement of said infusion needle.

Actively Opened Window Areas

10. The system of claim 1, wherein the outer wall comprises at least one door in the penetration area or areas, wherein a drive is connected to the at least one door for actively opening the door so as to allow for the at least one infusion needle to be advanced through the opened door.

11. The system of claim 10, wherein the drive connected to the door forms part of the drive unit coupled to the infusion needle.

12. The system of claim 10, wherein the door comprises a normally closed, resilient flap.

13. The system of claim 10, comprising at least one spring element urging the door into its closed position.

14. The system of claim 1, wherein at least two penetration areas are arranged in a single one of said at least one housing so that they can be placed either adjacent to both the right and left corpus cavemosum of the patient'"'"'s penis and/or the two deep arteries of the right and left corpus cavemosum and/or adjacent to muscle tissue regulating blood flow through the right and left corpus cavemosum.

Needle

15. The system of claim 1, 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.

(Long flexible needles)

16. The system of claim 1, wherein the at least one infusion needle is 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 housing and the other end thereof is arranged in a second housing for remote implantation inside the patient'"'"'s body, the injection needle being sufficiently long to bridge the 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.

17. The system of claim 16, wherein at least a part of the drive unit for advancing and retracting the tip end of the infusion needle is contained in the second housing.

18. The system of claim 16, wherein the drive unit for advancing and retracting the infusion needle comprises a screw drive connection.

19. The system of claim 18, wherein the screw drive connection comprises a threading on the infusion needle engaging a fixedly mounted rack.

20. The system of claim 16, wherein the infusion needle is guided in a sheath between the first and second housings.

6. The system of aim 2, wherein the self-sealing material is made from a composite material.

7. The system of claim 6, wherein the composite material comprises at least one outer shape-giving layer and a self-sealing soft material contained within the outer layer.

8. The system of claim 7, wherein the self-sealing soft material is a gel.
