Abstract: A metal probe for intracorporeal calculi crushing has a point at its distal end with one or several lateral notches next to the probe end. These notches secure a calculus laterally against an adjacent duct wall and thus prevent it from drawing aside when it is crushed by the notch.

Abstract: A metal probe for intracorporeal shock wave lithotripsy has a point at its distal end with one or several lateral notches next to the probe end. These notches secure a calculus laterally against an adjacent duct wall and thus prevent it from bursting when it is crushed.

Abstract: A device for treatment of human urinary incontinence in the form of a catheter which can be inserted into the urethra and carries a balloon arrangement which can be filled with fluid to close off the urinary bladder, where the balloon arrangement holds the catheter in the lumen of the bladder. The fluid can be admitted to and discharged from the balloon arrangement via at least one channel running along the catheter wall which is closed off at the distal end of the distal part of the catheter. A self-closing valve is formed at a proximal end of the proximal part of the catheter. A hydraulic actuating mechanism is also located in the lumen of the urinary bladder. The hydraulic actuating mechanism can be hydraulically actuated by mechanical pressure exerted on a compressible balloon located at the distal end of the catheter. The compressible balloon is filled with fluid and is connected to the actuating mechanism via a connecting channel.

Abstract: A device for the treatment of human urinary incontinence with a catheter which can be inserted into the urethra and carries a balloon arrangement which can be filled with fluid to close off the urinary bladder and to hold the catheter in the lumen of the urethra. The fluid can be admitted to and discharged from this balloon arrangement via at least one closed channel running along the catheter wall which is closed off at the distal end of the catheter, and via a valve mounted at one proximal end section of the catheter in inserted condition. The length of the catheter is dimensioned such that its distal end in inserted condition lies within the urethra. A hydraulic actuating mechanism, also located in the lumen of the urinary bladder, is assigned to the self-closing valve.
