STIMULATION OF PENIS ERECTION

摘要

A penis erection stimulation system comprises a fully implantable drug delivery device for delivering a drug in relation to a penis to achieve erection of the penis. The drug delivery device may comprise a catheter adapted to be implanted in the corpora cavernosa of a penis or in close proximity thereto in order to deliver drugs through said catheter. Alternatively, one or more infusion needles may be disposed within and implanted along with one or more housings adjacent the patient's left and right corpora cavernosa. A reservoir and a pump may also be 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.

主权项

1. A method of implanting a penis erection stimulation system, 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 noninvasively 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 the penile tissue placed inside a human body where the left and right corpus cavernosum are deviating away from each other, and wherein the method comprising the step of:
cutting the skin, 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 patient's left and right corpus cavernosum and another kind of tissue in close proximity to the patient's left and right corpus cavernosum, so as to allow for stimulation of penis erection by delivering a drug, and placing the at least one infusion needle in a first position in the body in between the left and right corpus cavernosum at a base of the penile tissue placed inside a human body where the left and right corpus cavernosum are deviating away from each other.
