ABSTRACT:
A balloon dilatation catheter device and method adapted for use in percutaneous transluminal angioplasty, where the catheter has several lumens so arranged to more efficiently channel and cleanse harmful materials from within the catheter, thereby preventing dangerous materials, such as air, from entering the body cavity where air or other gas or liquid may cause harm or death. The device includes a balloon inflation lumen for inflating/deflating a balloon on the distal end of the catheter, and a directional flow lumen having a one-way valve, which prevents flow in the reverse direction. The catheter may also include a guidewire lumen for introducing guidewires or liquids into the proximal end of the catheter for use in the distal end, which may lie within a body lumen.
