ABSTRACT:
An innerless dilatation balloon catheter uses a balloon 22 which is longitudinally compliant so that it elongates as it is inflated. The catheter 10 includes a valve 30 which is responsive to elongation of the balloon 2 for effectively blocking fluid flow through a lumen extension 24, 26 through which the guide wire 12 passes. The valve 30 allows the guide wire 12 to move freely when the balloon 22 is deflated.
