Abstract

The infusion erectile system prosthesis includes a dispensing device implanted in a scrotal sac or subcutaneously in an area adjacent the scrotal sac. The dispensing device includes a reservoir for storing erection stimulating material and a pumping arrangement for actuating movement of the erection stimulating material from the reservoir through a flow tube that joins the penis. The flow tube penetrates a peripheral portion of the penis and communicates with the corpus cavernosum. Infusion of the erection stimulating material into the corpus cavernosum causes an erection to occur. The pump which actuates movement of the erection stimulating material is actuatable manually or electrically.

Claims

1. A prosthesis for synthesizing an erection comprising, dispensing means for infusing a first predetermined amount of an erection stimulating material into the penis, said dispensing means including reservoir means for storing a second predetermined amount of said erection stimulating material, flow means communicable with said reservoir means and communicable with said penis for directing flow of said first predetermined amount of erection stimulating material into said penis, and pumping means for actuating movement of said erection stimulating material from said reservoir means through said flow means and into said penis, wherein said pumping means includes control means for enabling said pumping means to pump a predetermined amount of said erection stimulating material only after a predetermined minimum time delay form the last actuation of said pumping means.

2. The prosthesis as claimed in claim 1 wherein said pumping means include a pump chamber and said control means include an orifice for establishing a predetermined rate of flow of said erection stimulating material from said reservoir means to said pump chamber.

3. The prosthesis as claimed in claim 2 wherein said pumping means is manually actuatable.

4. A prosthesis for synthesizing an erection comprising, dispensing means for infusing a first predetermined amount of an erection stimulating material into the penis, said dispensing means including reservoir means for storing a second predetermined amount of said erection stimulating material, flow means communicable with said reservoir means and communicable with said penis for directing flow of said first predetermined amount of erection stimulating material into said penis, and pumping means for actuating movement of said erection stimulating material from said reservoir means through said flow means and into said penis, wherein said flow means include outlet means for outletting the erection material into the penis and attachment means for joining said flow means to said penis to fix the position of said outlet means in said penis.

5. The prosthesis as claimed in claim 4 wherein said erection stimulating material is papaverine.

6. The prosthesis as claimed in claim 4 further including metering means for metering the erection stimulating material moving from said reservoir means to said flow means, to said first predetermined amount.

7. The prosthesis as claimed in claim 6, wherein said metering means meters the first predetermined amount of said erection stimulating material to one bolus.

8. The prothesis as claimed in claim 4, wherein said outlet means includes an outlet member communicable with the corpus cavernosum of the penis.

9. The prosthesis as claimed in claim 8, wherein said flow means include a pair of outlet members communicable with respective corpus cavernosum of said penis.

10. The prosthesis as claimed in claim 4, wherein said reservoir means includes septum means for permitting refill of said reservoir means with said second predetermined amount of said erection stimulating material.

11. The prosthesis as claimed in claim 4, wherein said dispensing means is implanted in a scrotal sac.

12. A method of producing an erection in individuals with erectile dysfunction comprising the steps of:

(a) implanting a dispensing means for dispensing erection stimulating material, said dispensing means including flow means communicating with the penis for diverting flow of said erection stimulating material into said penis, said flow means including an outlet means for outletting the erection material into the penis;

(b) securing said flow means to the penis so as to fix the position of the outlet means to the penis; and

(c) providing means accessible to the individual for controlling the infusion of said erection stimulating material by the dispensing means.

13. The method of claim 12, wherein the erection stimulating material is papaverine.

14. The method of claim 12 wherein the flow means has a member mounted thereon and the step of securing includes suturing the member to the penis.

15. The method of claim 12 wherein the flow means has a disk attached thereto and the step of securing includes suturing the disk to the penis.
