Cardiovascular catheter having discrete regions of varying flexibility

Abstract

Abstract A flexible cardiovascular catheter (10a) at least a first proximal section, (54a) a second intermediate section (56a) which is more flexible than the first proximal section and a third distal section (58a) which is more flexible than the second intermediate section. The second intermediate section (56a) is of constant rigidity along its entire length. Curvatures may be formed in the catheter to facilitate insertion and positioning of the catheter in desired blood vessels. Presently preferred embodiments of the catheter are particularly usable as coronary artery guiding catheters or coronary angiography catheters.
