Implantable hydraulic penile erector
First Claim
1. An implantable hydraulic penile erectile device, comprising:
- a pair of compression means engageable with the crura of the penis for compressing said crura and the deep penile veins therein when activated and for releasing said crura and said deep penile veins when deactivated;
each of said compression means being implanted into the penis and extending around a respective crus, andcontrol means for selectively activating or deactivating said compression means,whereby said control means can be used selectively to cause said penis to become flaccid or erect.

Abstract
An implantable hydraulic penile erectile device comprises a pair of occlusive cuffs (32 and 34) which are surgically implanted and wrapped around respective crura (18 and 20). The cuffs have expandable domes (56) on their inner surface (54). The domes are connected, via a check valve (44) and respective tubes (36, 38, 64, and 66), to a pump-reservoir (42). The pump-reservoir and the check valves are implanted in the scrotum. The system in general is filled with a working fluid so that when the pump-reservoir is squeezed, the working fluid is shifted to the expandable domes via the check valve. Expansion of the domes squeezes the crura of the penis and hence the deep penile veins (26a and 26b). This restricts venous blood flow from the cavernous bodies, causing engorgement of the spongy tissue and thus inducing erection. For deactivation of the device, the user squeezes the check valve so that bypass channels (68 and 70) are formed therein. Through these channels the fluid can return from the domes back to the pump-reservoir.

10. An implantable hydraulic penile device comprising:
-
a pump-reservoir which is filled with a working fluid; a releasable check valve connected to said pump-reservoir by a first flexible tube; a pair of compression means engageable with the respective crura of the penis and connected by second and third flexible tubes to said check valve, said compression means each being arranged to compress a respective crus and the deep penile vein therein when activated and to release said crus and said deep penile vein therein when deactivated; each of said compression means being implanted into the penis and extending around its respective crus, whereby said control means can be used selectively to cause said penis to become flaccid or erect. - View Dependent Claims (11, 12, 13, 14, 15)

16. A method for selectively creating a penile erection, comprising:
-
providing means, which, when activated, will compress both crura of the penis and hence the deep penile veins therein sufficiently to cause said penis to become erect, and when deactivated, will allow said penis to become flaccid; providing control means for selectively activating or deactivating said compression means; and causing said control means to activate said compression means when an erection is desired and deactivate said compression means when an erection no longer is desired. - View Dependent Claims (17, 18, 19, 20)
