Abstract
A catheter (10, 40, 49, 53, 60, 90) having a balloon (24, 42, 50, 55, 74, 92) with a varying resiliency. A catheter body (16, 68) having a fluid delivery lumen (20, 62) extending therethrough is provided, with the balloon preferably being located at the distal portion. The balloon is securely attached to the catheter body at a first portion (30) and has a second portion (28) having a varying resiliency. A mid-section of the balloon having a lower resiliency (26) is more elastic than the second portion having the higher resiliency (28). The varying resiliency balloon may be achieved with varying durometer materials, or by varying the thickness of the balloon including increasing the thickness of the second portion. The varying resiliency balloon allows the catheter tip to self-align within a body vessel when the balloon is inflated to prevent impinging delivered fluid upon a vessel wall, and also preventing obstruction other extending body vessels. A flange (84) aids in positioning of the catheter within the body vessel, and a rigid member (70) allows for ease of insertion and positioning within a body vessel. The less resilient middle portions of the balloon may be angled with respect to the catheter body to further self-align the catheter within a body vessel.
