Urethral catheter

Abstract

Abstract The catheter has a main channel which opens into the bladder and which is provided with a seal and, if appropriate, with an inflatable chamber which is arranged near the inner end and whose state of expansion can be controlled from the outside via a connecting channel. According to the invention, there is also formed in the catheter an additional supply channel which is accessible from the outside and which, with the catheter in the inserted state, opens into the urethra before the prostate gland and is used for supplying a medicinal treatment agent into the urethra. This supply channel in the most straightforward case has a single outlet opening, but it is expedient for the supply channel, in the area of its opening on the urethra side, to open into an annular channel which has a number of outlets distributed around the catheter periphery. In addition, or alternatively, it is also possible for the supply channel to be guided around the catheter periphery in a helical formation and to be provided with a number of outlets arranged at a distance from one another. <IMAGE>
