Abstract:
1. A male sexual impotence treatment apparatus, comprising an adjustable restriction device implantable in a male impotent patient for directly engaging a portion of the normal penile tissue or the prolongation thereof of the patient, and an operable adjustment device implantable in the patient for adjusting the restriction device to temporarily contract said portion of the normal penile tissue or the prolongation thereof to restrict the blood flow leaving the penis, when the patient desires to achieve erection, wherein said adjustment device comprises: a hydraulic means for operating the adjustment device, comprising: (i) a first adjustable reservoir containing hydraulic fluid and being operatively connected to the restriction device, (ii) a second adjustable reservoir operatively connected to the first adjustable reservoir such that changes in the amount of fluid in the second adjustable reservoir causes larger changes in the amount of fluid in the first adjustable reservoir, the changes in the amount of fluid in the first reservoir causing corresponding adjustments in the restriction device, and thereby, corresponding changes in restriction of the penile tissue or the prolongation thereof engaged by the restriction device, (iii) a third reservoir adapted for subcutaneous implantation, and (iv) a hydraulic tube that hydraulically interconnects the second and third reservoirs and that separates the second and third reservoirs from each other, wherein the third reservoir is adjustable to change the amount of fluid therein to cause fluid flow in the hydraulic tube and a change of amount of fluid in the second reservoir, and wherein the third reservoir is smaller than the first reservoir.
