Claim 0:
1. A method of making a balloon catheter, comprising:
necking a tubular member of polymer material to form a monolithic single-layer distal outer member necked along an entire length thereof with the polymer material consisting essentially of polymer chains in a linear orientation;
providing a hypotube;
coupling a proximal end of the monolithic single-layer distal outer member to the hypotube to form an outer shaft having an inflation lumen defined therethrough;
providing a balloon in fluid communication with the inflation lumen, the balloon having a distal balloon shaft, a distal cone portion, a distal shoulder, a working length, a proximal shoulder, a proximal cone portion, and a proximal balloon shaft;
coupling the proximal balloon shaft to a distal end of the monolithic single-layer distal outer member; and
providing a monolithic inner tubular member having a guidewire lumen defined therethrough, the monolithic inner tubular member extending distally from a proximal port in the monolithic single-layer distal outer member through the balloon to form a tip.
