Device for controlling the flow of a fluid and a prosthetic organ equipped with this device
First Claim
1. A device for controlling the flow of a fluid in a duct, comprising:
- first and second flexible activating bags containing an activating fluid;
a connecting tube for connecting said first and second bags;
valve means responsive solely to the pressure of said activating fluid obtained by manual deformation of one of said first and second activation bags,said valve means comprising a valve seat in the form of a rod located inside said connecting tube,wherein said connecting tube comprises a valve element formed of a flexible plastic material for sealing clamping said rod,said first bag being adapted to effect upon deflation by manual deformation, the re-establishment of the flow of fluid in a duct, whereas the second activating bag is adapted to effect, also by deflation by manual deformation, cancelling of said flow;
clamp means for reinforcing the sealing clamping of said rod in a rest condition inside said connecting tube, andmeans for preventing said rod from leaving said connecting tube under the effect of said pressure wherein the clamping action of said connecting tube and said clamp means is overcome solely by said pressure.

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.

2. A device for controlling the flow of a fluid in a duct, comprising:
-
first and second flexible bags containing an activating fluid; a first connecting tube for interconnecting said first and second bags containing an activating fluid; a third flexible bag communicating with said first and second activating bags; a connecting pipe for connecting said third bag to one of said first and second activating bags; valve means responsive solely to the pressure of said activating fluid obtained by manual deformation of one of said first and second activating bags, said valve means comprising a valve seat in the form of a rod located inside said connecting tube, wherein said connecting tube comprises a valve element for sealingly clamping said rod formed of a flexible plastic material, said first bag being adapted to effect, upon deflation by manual deformation, the re-establishment of the flow of fluid in a duct, whereas the second activating bag is adapted to effect, also by deflation by manual deformation, cancelling of said flow, wherein said third flexible bag is adapted to be inserted inside said duct in order to control the flow of said fluid through its deflation and inflation; clamp means for reinforcing the sealing clamping of said rod in a rest condition inside said connecting tube, and means for preventing said rod from leaving the connecting tube under the effect of said pressure, wherein the clamping action of said connecting tube and said clamp means is overcome solely by said pressure. - View Dependent Claims (10)
