This invention is a novel urethral plug (I) comprising a cooperating shaft (12) and balloon (18), lying in coaxial engagement. The balloon (18) possesses a contracted shape for insertion and removal through the opening of the urethra. and a larger, expanded shape for blocking the flow of urine in the urethra, bladder neck, and bladder. After insertion such an expanded shape is achieved by inflation of the balloon (18) through the use of an external source such as a syringe which introduces fluid through an opening and into the shaft. The fluid acts upon a ball valve (22), thus pushing the ball past a valve seat, thereby permitting fluid to travel through the shaft and into the balloon (18). Fluid transmission continues until the balloon (18) is expanded to such an extent as to block the flow of urine.
Il s'agit d'un nouveau bouchon urétral (1) comprenant une tige (12) et un ballonnet (18) fonctionnant de façon solidaire, placés en accouplement coaxial. Le ballonnet (18) est soit contracté, pour en permettre l'insertion ou le retrait par l'ouverture de l'urètre, soit dilaté, pour bloquer le flux d'urine dans l'urètre, le col vésical et la vessie. Après insertion, la forme dilatée du ballonnet (18) s'obtient par gonflage à l'aide d'une source extérieure telle qu'une seringue, qui introduit du fluide par une ouverture et dans la tige. Le fluide agit sur une soupape à bille (22), la bille étant poussée au-delà du siège de la soupape, permettant ainsi au fluide de passer dans le ballonnet (18) à travers la tige. Le transfert de fluide se poursuit jusqu'à ce que le ballonnet (18) soit gonflé au point de bloquer le flux urinaire.
