Abstract
An angioplasty catheter is disclosed having an elongate main body defining guide wire and fluid supply lumens and terminating at a distal end in a tapered tip. The fluid supply lumen is closed at the tip and the guide wire lumen extends to the tip for receiving a Seldinger wire to guide the catheter during insertion procedures. The main body defines a side opening meeting the supply lumen near the tip and a balloon is sealed to the main body near the tip and contains the side opening. The balloon has a membrane of inelastic material having a defined shape when inflated by fluid pressure applied through the supply lumen, and an elastic sheath covering the membrane.
