PROBLEM TO BE SOLVED: To provide a balloon catheter having a shaft with an improved combination of characteristics such as strength, flexibility, ease of manufacture, and lower cost.SOLUTION: A balloon catheter 100 includes: an outer shaft having a hypotube 220 and a monolithic single-layer distal outer member 230; a balloon 140 in fluid communication with an inflation lumen 200, 201, 202; and an inner tubular member 240 having a guidewire lumen 210 defined therethrough. The outer shaft has the inflation lumen 200, 201, 202 defined therethrough. The monolithic single-layer distal outer member 230 is necked to a reduced diameter along an entire length thereof. A proximal end of the monolithic single-layer distal outer member 230 is coupled to the hypotube 220.SELECTED DRAWING: Figure 1 |
