Implantable penile venous compression device: initial experience in the acute canine model

We have designed a venous compression device implantable at the base of the penis outside the tunica albuginea. Because it does not require exposure of individual veins for ligation, the risk to the cavernous nerve is practically nil. It occludes the venous return only temporarily, and thus collaterals are less likely to occur. In this preliminary acute study in dogs (N = 13), the penile venous compression device was shown to be effective and safe in controlling penile venous drainage and maintaining rigid erection.
