ABSTRACT:
A balloon angioplasty catheter having a balloon head assembly carried at the distal end of an elongated catheter body. The balloon head assembly includes an inflatable balloon envelope and a perfusion lumen extending through the balloon envelope to provide a blood flow passage during inflation of the balloon envelope. In a preferred embodiment, the perfusion lumen is formed by a helical member having spaced coils encapsulated with a flexible material. A discharge lumen is formed by a projecting tip, the tip being integrally formed with the balloon envelope. Discharge orifices are provided through the tip sidewall. In a preferred embodiment, the side discharge orifices are elongated in the general direction of perfusion flow through the balloon head. The invention also encompasses means for facilitating discharge of perfused blood through the discharge orifices. This is accomplished by valving perfusate flow through the discharge lumen.
