Penile prosthesis

A male sexual impotence treatment apparatus, comprising an adjustable prosthesis device (2) implantable in the corpora cavernosa or other parts of a male impotent patient's penile tissue, an implantable hydraulic adjustment device (5) for adjusting the prosthesis device to temporarily achieve erect status of the penis, an implantable operation device (6,8;10;12;10,14;76-86) for operating the hydraulic adjustment device, a reservoir implantable in the patient and containing hydraulic fluid, and a conduit providing fluid connection between the reservoir and the hydraulic adjustment device, characterised in that the operation device is adapted to operate the hydraulic adjustment device by distributing hydraulic fluid through the conduit between the reservoir and the hydraulic adjustment device, the conduit and hydraulic adjustment device being devoid of any non-return valve to permit free flow of hydraulic fluid in both directions in the conduit.

A male sexual impotence treatment apparatus, comprising an adjustable prosthesis device (2) implantable in the corpora cavernosa or other parts of a male impotent patient's penile tissue, an implantable adjustment device (5) for adjusting the prosthesis device to temporarily achieve erect status of the penis, and an implantable operation device (6,8;10;12;10,14;76-86) for operating the adjustment device, characterised in that the operation device comprises a servo means.

An apparatus according to any of the preceding claims, further comprising a wireless remote control (44,126,132-144) for non-invasively controlling the hydraulic operation device (6,8;10;12;10,14;76-86).

An apparatus according to any one of the preceding claims, wherein the operation device is electrically powered.

An apparatus according to any one of the preceding claims, further comprising at least one implantable sensor for sensing at least one physical parameter of the patient.

An apparatus according to any of the preceding claims, further comprising a switch implantable in the patient for directly or indirectly switching the operation of the prosthesis device.

An apparatus according to any of the preceding claims, wherein the prosthesis device is embedded in a soft or gel-like material.

An apparatus according to any of the preceding claims, wherein the prosthesis device is adapted to engage the corpora cavernosa or crura as a single unit.

An apparatus according to any of the preceding claims, wherein the prosthesis device further comprises two prosthesis members adapted to engage the respective corpora cavernosa or crura.

An apparatus according to any of the preceding claims, wherein the adjustment device is adapted to adjust the prosthesis device such that the prosthesis device provides a predetermined adjustment of the corpora cavernosa or crura or the prolongations thereof that is satisfactory for the patient.
