ABSTRACT:
A device for controlling the flow of a fluid, more especially a biological fluid and in particular the urinary flow, the device including a rod which, in the rest condition, is sealingly clamped, by any appropriate clamping mechanism, inside a connecting tube, and which is made from a flexible plastic material presenting shrinkage on polymerization, and a mechanism which is adapted to prevent the axial movement of the valve rod along the connecting tube under the effect of the pressure of a fluid filling two flexible activating bags connected through the connecting tube, which may be incorporated with a third flexible bag. A prosthetic organ is formed by a urethral prosthesis of the interchangeable type including a tube made, for example, from silicon elastomer and a plurality of spurs formed on its outer surface and preventing any axial movement thereof, some of which are directed downwards, whereas the remainder are directed upwards, which prosthetic organ further includes, at the proximal end of the tube a mechanism providing sealing with respect to the bladder cooperates with the device for controlling the urinary.
