Abstract
A male sexual impotence treatment apparatus comprises an adjustable non-inflatable restriction device (434) implanted in a male impotent patient. The restriction device directly engages a portion of the normal penile tissue of the patient, such as both of the corpora cavernosa as a single unit or one or more of the exit veins from the penis, to affect the blood flow leaving the penis. An adjustment device (436) mechanically adjusts the restriction device to temporarily restrict the blood flow leaving the penis when the patient wishes to achieve erection.
