A device providing erection assistance includes an open-ended and radially elastic tubular cuff adapted to fit over a male penis. The cuff's length is such that it can extend from the base of the penis to as far as the corona thereof. The cuff includes at least one wall region defining a void region along the wall region's length.

A pump adapted for use with an implantable penile prosthetic includes an inlet flow path formed in a pump body having a first portion communicating between a reservoir and an inlet valve and a second portion communicating between the inlet valve and the pump bulb. The inlet valve includes a spherical part having a groove formed on an exterior surface of the spherical part.

A system for inducing and sustaining an erection of a penis a vacuum assembly and a ring assembly adapted to encircle the penis. An inflatable ring assembly disposed in an outwardly flared proximal end of the tube. The ring assembly forms a central circular opening adapted for receiving the penis. A rigid annular ring support is disposed within the ring. A fluid pump is selectively coupled to a valve in the ring assembly, and the pump is adapted to introduce the bladder-inflating fluid under pressure. Expansion of the ring assembly causes the inner surface of the ring assembly to expand while being substantially fixed by the ring support against outwardly radial deformation. A compressive force is thus introduced around the surface of the penis for constricting blood flow from the penis sustain the erection.

A method of providing a patient with an implanted penile prosthetic adapted to provide improved flow of blood to a glans penis dilating a first portion of tissue in the corpora cavernosum and creating a first space and leaving a segment of vascularized tissue in the corpora cavernosum un-dilated and undisturbed, and engaging a channel formed in an exterior surface of a penile prosthetic with the segment of vascularized tissue.

A pump includes a pump bulb connected to a pump body. An exhaust valve assembly is disposed in the pump body within an exit flow path communicating between the pump bulb and the cylinder. An inlet valve is rotatably disposed in the pump body within an inlet flow path communicating between the reservoir and the pump bulb. The inlet valve includes a spherical part retained in a seat formed by the pump body, an inlet flange connected to and extending radially away from the spherical part, and a lockout flange connected to and extending radially away from the spherical part. A channel is formed through a portion of the spherical part of the inlet valve. The channel includes an outlet hole that is blocked from the inlet flow path by the seat formed in the pump body and opened to the inlet flow path by rotation of the inlet valve.

An erection-facilitating sleeve for counteracting the effects of erectile dysfunction. The erection-facilitating sleeve includes two open ends at each distal end spaced apart by a plurality of inflatable, semi-rigid passages that extend in a braided, or crisscross, configuration from the base to the top of the sleeve. The sleeve is inserted onto the penis and is made of a resilient material that wraps tightly around the sex organ of a user. The semi-rigid passages are of a predetermined material and thickness so that a user's sex organ maintains at least partially erect even while suffering from erectile dysfunction.

A method of implanting a penile prosthetic includes providing a tool having a barrel with a first groove formed in an exterior surface of the barrel and a second groove formed in the exterior surface of the barrel; capturing opposing lateral edges of a deflated penile implant into the respective the first groove the second groove; placing the barrel of the tool and the deflated penile implant into a corpora cavernosum of a penis; removing the barrel from the corpora cavernosum of the penis and leaving the deflated penile implant in the corpora cavernosum of the penis.

A method of making an implantable fluidic pump includes applying a stress to a flat metal foil to form the foil into a non-flat configuration and, while the metal foil is in in the non-flat configuration, attaching the metal foil to a flat surface of a metal base plate to form a chamber between the foil and the flat surface. Then, while the metal foil is in in the non-flat configuration and attached to the flat surface of the metal base plate, a piezoelectric element is attached to the foil, where the piezoelectric element is configured to change a distance between the foil and the flat surface of the metal base plate.

The apparatus described is an inflatable constriction ring device to constrict the venous outflow from penis. The inflatable constriction ring is used in combination with vacuum erection device (VED), which induces erection and the ring constricts the venous outflow at the base of the penis to maintain erection.

The distal end of constriction ring device is mountable on the proximal end of vacuum erection device to make a sealable contact with the vacuum erection device. The constriction ring is configured to make sealable contact with the user's skin around the penis thus creating an airtight system. The constriction ring is attached to the tubing of the inflation/deflation pump, which is used to inflate the constriction ring.

Techniques are disclosed for controlling fluid flow between a fluid reservoir and an inflatable member in an implantable fluid-operated device. Energy received from an external power transmission device is provided to charge a rechargeable battery of the implantable fluid-operated device. A waveform of electrical energy from the rechargeable battery is provided to a first piezoelectric element of a first piezoelectric pump of the implantable fluid-operated device to drive the first piezoelectric element to pump fluid from the fluid reservoir to the inflatable member. At least one capacitor of the implantable fluid-operated device is charged in response to a voltage generated by the first piezoelectric element when the first piezoelectric element returns to its neutral shape from a deformed shape. And the rechargeable battery is prevented from being charged based on the voltage generated by the first piezoelectric element.
