A penile prosthesis is provided, which includes a generally cylindrical body portion comprising a cavity with an inner wall, a proximal end, a distal end, and at least one volume-displacing member occupying at least a portion of the cavity, wherein the at least one volume-displacing member is smaller in at least one dimension than the dimensions of the cavity to provide an internal chamber at least partially surrounding the at least one volume-displacing member and adjacent to the inner wall of the cavity. The prosthesis further includes a fluid transfer tube extending from the body portion for transferring fluid to and from the internal chamber, wherein the device is convertible from a flaccid condition to a rigid condition when a sufficient volume of fluid is transferred into the internal chamber to substantially fill the internal chamber.

An inflatable penile prosthesis cylinder of the present invention includes an inflatable chamber and a constraining sleeve of fabric. The inflatable chamber is configured to expand in response to an increase in pressure within the chamber. The sleeve of fabric constrains the expansion of the chamber, however, the sleeve of fabric includes a corrugation that facilitates some expansion of the sleeve.

An inflatable penile prosthesis of the present invention includes a cylinder that has an external wall that defines a pressure chamber. That external wall preferably incorporates a number of corrugations that extend in a longitudinal direction of the cylinder. In a preferred embodiment, the external wall of the cylinder is formed of a polyurethane or of a material having a modulus of elasticity greater than that of silicone. The corrugations enable the cylinder to move from a small, deflated diameter to a much greater diameter in the inflated state.

An implantable inflatable penile prosthesis cylinder has a longitudinal axis and includes an inflatable portion. The inflatable portion includes a chamber that defines an inflatable chamber. The chamber wall includes at least one thin wall section and at least one thick wall section. The at least one thin wall section stretches a greater amount than the at least one thick wall section in a plane extending perpendicular to the longitudinal axis when the inflatable chamber is transitioned from a deflated state to an inflated state.

An implantable inflatable penile prosthesis cylinder includes an outer tube member having a longitudinal axis, an inner tube member contained within the outer tube member, and one or more tensile support members within the inner tube member. The inner tube member includes at least one inflatable chamber section, at least a portion of which is defined by a wall of the inner tube member. The one or more tensile support members extend between interior surfaces of the wall, and are placed in tension when the at least one chamber section is in an inflated state.

According to an aspect, an inflatable penile prosthesis includes an inflatable member, a reservoir configured to hold fluid, and a pump assembly configured to facilitate a transfer of the fluid from the reservoir to the inflatable member when the prosthesis is in an inflation mode and facilitate a transfer of the fluid from the inflatable member to the reservoir when the prosthesis is in a deflation mode. The pump assembly includes a pump, a valve body having a first valve and a second valve, and a selection member defining a lumen, the selection member being movable from a first position to place the prosthesis in the inflation mode and a second position to place the prosthesis in the deflation mode.

A low profile rear tip for inflatable penile prostheses comprises a proximal end portion, and a distal end portion that is capable of being coupled to a cylinder of an IPP along a major longitudinal axis between the proximal end portion, the distal end portion, and the cylinder. A fluid chamber is provided in the distal end portion, in fluid communication with the cylinder. A fluid conduit is integrally formed with the distal end portion, having a minor longitudinal axis and being in fluid communication with the fluid chamber in the distal end portion, wherein an angle between the minor longitudinal axis and the major longitudinal axis does not exceed 5 degrees.

Embodiments of the present disclosure include a system for anchoring implantable medical devices to bones. It includes an implantable medical device such as an inflatable penile prosthesis, a sliding edge clamp for anchoring at least partially around a bone, and a prosthesis receptacle coupled to the sliding edge clamp and extending outwardly and positioned to receive the prosthesis.

Disclosed is a locking needle to be used with a Furlow insertion tool during penile prosthesis. The invention also provides methods of using the locking needle for the implantation of a penile prosthesis cylinder.

According to an aspect, an inflatable penile prosthesis (200) includes an inflatable member (204), the inflatable member having a reinforced portion; a reservoir (202) configured to hold fluid; and apump assembly (201) configured to facilitate a transfer of the fluid from the reservoir to the inflatable member when the prosthesis is in an inflation mode, and facilitate a transfer of the fluid from the inflatable member to the reservoir when the prosthesis is in a deflation mode.

According to an aspect, an inflatable penile prosthesis (299) includes an inflatable member (204), a reservoir (202) configured to hold fluid, and a reversible flow pump assembly (201) configured to facilitate a transfer of the fluid from the reservoir to the inflatable member when in an inflation mode, and facilitate the transfer of the fluid from the inflatable member to the reservoir when in adeflation mode. The reversible flow pump assembly includes a pump (206), an input check valve (210) coupled to the pump, an output check valve (212) coupled to the pump, and a reversing valve (208). The input check valve is configured to permit transfer of fluid into the pump. The output check valve is configured to permit transfer of fluid out of the pump. The reversing valve is configured to switch between the inflation mode and the deflation mode.

According to an aspect, an inflatable penile prosthesis (200) includes a reservoir (202) configured to hold fluid, an inflatable member (204), and a pump assembly (201) configured to facilitate a transfer of a fluid from the reservoir to the inflatable member. The pump assembly includes a pump bulb (231), and a valve body (440) defining a fluid passageway. The valve body includes a refill valve (450) disposed in the fluid passageway. The refill valve includes a valve member (464). In response to the pump bulb being compressed, the valve member moves within the fluid passageway in a first direction to a closed position in which the valve member blocks the fluid from being transferred around the refill valve. In response to the pump bulb being uncompressed, the valve member moves within thefluid passageway in a second direction to an open position in which the valve member allows the fluid to transfer around the refill valve.

A penile prosthesis (100) including an inflatable member (104) and a pump assembly (101) configured to facilitate a transfer of a fluid from a reservoir (102), configured to hold fluid, to the inflatable member. The inflatable member defines a lumen and includes a structural member (108). At least a portion of the structural member is disposed within the lumen defined by the inflatable member.

According to an aspect, an inflatable penile prosthesis (900) includes a fluid reservoir (902) configured to hold fluid, an inflatable member (910), and a pump assembly (906, 206) configured to transfer the fluid between the fluid reservoir and the inflatable member. The pump assembly (206) includes a valve body having one or more valves, and an outer protective casing (220) disposed over the valve body.

According to an aspect, an inflatable penile prosthesis includes a fluid reservoir, an inflatable member, and a pump assembly. The pump assembly includes a pump bulb, a valve body, a push valve movably coupled to the valve body, a first fluid port, and a second fluid port. The push valve includes a movable valve element configured to move between an inflation position and a deflation position within a bore of the valve body. The movable valve element in the inflation position defines a fluid passageway through the bore to transfer fluid from the pump bulb to the second fluid port. The movable valve element, when moved to the deflation position, is configured to change the fluid passageway through the bore to transfer fluid from the second fluid port to the first fluid port such that the pump bulb is bypassed.
