Abstract

L'invention concerne un cathéter intraurétral de contrôle urinaire, qui comprend une valve commandant l'écoulement d'urine et une microvalve auto-obturatrice permettant et facilitant l'utilisation d'une aiguille mousse ou d'une canule pour remplir et vider le ballon. La microvalve permet d'introduire l'aiguille ou la canule avec une résistance minimale tout en présentant une étanchéité adéquate lorsque le ballon est plein et lorsque l'aiguille ou la canule est retirée.
