The balloon dilatation catheter has a first lumen (8) which extends over the entire length of a shaft (21) and which is connected to a pump (14) and, at the distal end of the catheter (1), to the inside (5) of the balloon (22). A supporting wire (3) connected securely to the catheter (1) also passes through this lumen (8). The shaft (21) has a further lumen (9) which opens outwards through an opening (10) behind the proximal end of the balloon (22). A controllable guide wire (20) can be introduced into this lumen (9) via a connection piece (16). Similarly, a measuring device (19) or a device for introducing a contrasting medium or medicament can be connected to this further lumen (9). The catheter (1) is particularly suitable for treating strictures in an arterial ramification. <IMAGE> |
