Abstract
A shaft of a catheter system of the invention is used for PTCA, angiography, perfusion, drug delivery or the like in a body of a patient. The shaft is formed of a tube and a plurality of ribs projecting from an inner wall of the tube towards a center thereof. The respective ribs have a certain thickness, so that resisting force against a direction in which the shaft is bent or kinked is provided, and at the same time force or torque for manipulating the catheter system is transmitted from the proximal end to the distal end of the shaft.
