Excitable penile prostheses (EPP)

The essential thing about the EPP is that the penile prosthesis erectable - stiffenable - and that the mechanism and the hydraulic mechanism are within the prosthesis are located and not outside.

The state of the art includes various penile prostheses, which can be divided into 2 large ujad several subgroups.

1. Rigid prostheses (hard, semi-rigid, soft)

2. Excitable prostheses

a) Of these, only the insert according to Scott is known, the one from a container that is placed in another part of the body is being inflated. - Source: Scott and others: Management of erectible impotence Urologie 2:80 (1973) UNITED STATES. '/ more hydraulically movable inflatable prostheses are not known.

The previous versions of penile prostheses are characterized by the following defects:

The prostheses are rigid and therefore the male member remains in constant erection. However, this constant erection creates various unpleasant side effects in the patient. The inflatable prosthesis according to Dr. Scott has the disadvantage -aab the hydraulic system is unnaturally in other distant parts of the body, that the long tubes, with which the prosthesis is connected, is burdened with a large liomplikationsquotient.

The task of EPP is to eliminate erectile impotence. These Today, the task is routinely performed with rigid or other prostheses carried out. A relaxation is with the previous prostheses either not possible or too cumbersome with the Scottish prosthesis and too vulnerable.

The achievable advantages of EPP compared to the rigid prosthesis are erectibility, ie the avoidance of the permanent substitute state that exists with rigid prostheses. Compared to the Scott ^Λ fr see prosthesis, there is the advantage that the entire system | in the insert is that the many long channels, tubes, 'inflatable drums in other parts of the body (in the scrotum)!

The EPP is a penile prosthesis that is closest to the physiological j Circumstances of the male reproductive organ * The fact that the mechanism is hidden in the insert itself, ^ combines previous experience of simple implantation with a | new technology.

Slackening and resting of the EPP

The pressure in the valve chamber C is manually increased and the valve Vc is opened. Simultaneously if the pressure is manually exerted on chamber B, which exceeds the pressure of the spring (f) so far, that part of the liquid from chamber B passes back into chamber D. After the valve Vc is closed at the same time, the pressure in chamber B is lower than in chamber B. So the position - relaxation is reached.

Technical details for

Design of the pressure chamber D

Chamber D and valve systems Va and Vc are integrated. The dimensions of the chamber D amount to approx. 7 cm in length and approx. 8 mm in diameter. It is a conically shaped proximal T _u bus from V2A steel, in which a precision piston and a powerful spring (about 00 millibar **) are included. The microvalve system with a diameter of approx. 3 mm is connected to the dystal end.

The valves are opened by pressure from valve chamber ¹ (A and c), when the pressure drops, the valve closes the passage through the spring system, which brings the valve piston to the rest position.

pushes the liquid from chamber D into chamber B.

Pressure on the chamber A actuates the opening of the inlet valve Va. The spring (F) expands and pushes the Liquid from chamber D into chamber B. The pressure in chambers D and B is now equalized, with the stiffening the prosthesis takes place. The pressure in chamber B is the same as the maximum pressure during the erection Spring (f) can produce.

The prosthesis is made of medical silicone compound, which is subject to changing pressure conditions. The drive pressure is generated by a spring. So "the main parts of the SPP consist of silicone shell, metallic Spring and microhydraulic IT parts.
