Abstract
A fixed-wire type of balloon dilatation catheter has a small diameter and can be steered to and passed to and through narrow stenoses. The catheter has a balloon at its distal end which is collapsible to a low profile to enable it to be passed through the stenosis. The catheter includes a connection between the distal end of the balloon and the supporting core wire which displays the least resistance to twisting about the core wire when the core wire is rotated with respect to the balloon and the balloon is subsequently inflated. Consequently, any twisting of the catheter about the wire will occur distally of the balloon so as not to obstruct fluid flow through the balloon.
