ABSTRACT:
A guiding catheter or angiographic catheter and method of manufacture for use in cardiovascular interventions which incorporates an annealed low-flexibility proximal zone wherein a transition zone separates the proximal zone and a high-flexibility distal zone. The catheter is subjected to a slicking operation to improve the smoothness of the high flexibility distal zone in order to better traverse the aortic arch shape while reducing excess energy storage. The proximal zone is annealed to provide a high level of stiffness for optimal support and pushability. A mid-region zone transitions the high stiffness of the proximal zone to the higher flexibility of the distal zone to eliminate buckling and kinking.
