ABSTRACT:
An angiographic catheter which comprises a relatively stiff, tubular, basic catheter body and a less-stiff, tubular, end part connected to one end of the basic body. The end part has a curved form which comprises at least first and second tubular portions, each defining part of the curved form. The first and second tubular portions comprise materials of different stiffness, with the tubular portions being connected to one another in end-to-end relation. Preferably, a straight segment of a first tubular portion is connected in end-to-end relation with the basic catheter body, which catheter body preferably carries a fibrous, tubular reinforcing sheath. Preferably, the stiffness of the material of the tubular portions decreases in the direction extending from the basic body towards the one end.
