Abstract
An intravascular catheter, such as an angiography catheter, has a tubular body portion formed from a nylon such as nylon-11 which has strength and stiffness characteristics providing excellent torqueability, burst strength, and longitudinal rigidity. A soft tubular tip is fused to the end of the body portion to form a continuous tubular catheter. The soft tip is formed from a blend of the nylon of the body portion with an ester linked polyether-polyamide co-polymer which is soft and rubbery to render the tip soft to avoid injury to a blood vessel.
