ABSTRACT:
The invention relates to a catheter comprising a tube-like basic body with a proximal and a distal end and an expandable balloon member arranged close to the distal end to the basic body. The balloon member comprises a number of relatively stiff sections extending on a small diameter in a longitudinal direction of the basic body and relatively pliable sections extending inbetween, wherein the relatively pliable sections form lobes in an expanded state of the balloon member. The invention furthermore relates to a method for manufacturing a catheter according to the invention, wherein a piece of tube-like basic material is provided and, by blow molding, a balloon member is made in a mold, which is arranged to the bias material. The balloon member is manufactured in the mold cavity of a mold, the cross-section of which is lobated, by receiving a tube-like partial manufacture inside it and deforming it by blow molding into a shape corresponding to that of the shape of the mold cavity.
