ABSTRACT:
A balloon catheter defines a balloon having a cylindrical outer surface of a diameter essentially no greater than the diameter of the tubular shaft. Additionally, a method is disclosed in which one inserts a catheter into the arterial system of a patient, and increasingly pressurizes a balloon made of work-hardenable material to elastically expand the balloon to such a first pressure that sufficient work-hardening takes place in the expanding balloon to cause the diameter of the balloon to substantially cease its expansion in response to a pressure range increasing from the first pressure. One then terminates the increase of the pressure at that point to cause the catheter to assume a first, predetermined maximum diameter. Catheter balloons can each be expanded to two different, known, work-hardened diameters by this invention.
