Abstract
A balloon catheter for medical treatment of a patient has a proximal hub, flexible catheter shaft, a balloon, and an improved tip design. The catheter defines a guidewire lumen defined by a tubular inner body extending from a distal guidewire port to a proximal port located at a position proximal from the balloon. The guidewire lumen preferably has a constant cross-sectional area from the distal guidewire port to the proximal end of the balloon. At least one marker band is affixed to the inner body at a location within the balloon. A distal leg of the balloon is affixed to the inner body and a location between the marker band and the distal end of the inner body. A portion of the inner body extending in the proximal direction from the marker band has a substantially constant inner lumen diameter. However, the inner body wall thickness tapers to a narrower tip wall thickness, extending from a location between the marker band and the balloon distal leg, to the distal end of the inner body. A distal portion of the distal leg is also preferably tapered.
