Abstract
This intravascular catheter comprises a multi-aperture pipe design for the perfusion of medicines which are mutually incompatible in their pure state or for carrying out several different functions. In order to permit the implantation of this catheter by the 'tunnelling' method, this multi-aperture pipe (1) forms only the distal part of this catheter. The catheter also comprises separate tubes (2a, 2b) equal in number to the apertures of the first pipe and which extend back from this pipe to form the middle part (2) of the catheter; and a single-aperture pipe (3) forming the proximal end of the assembly which terminates in a rigid needle (4) suitable for carrying out the tunnelling. Two connectors (5 and 6) serve respectively to join each aperture (1a, 1b) of the multi-aperture pipe (1) to one of the separate tubes (2a or 2b) of the middle part (2), and to connect the opposite ends of these tubes (2a, 2b) to the corresponding end of the single-aperture pipe (3). Each of these connectors is made of plastic and is molded onto the ends of the parts to be joined.
