ABSTRACT:
A slip-layered balloon catheter for insertion into a bodily conduit, especially an artery. The catheter comprises a shaft (21) having at least one lumen (26) for delivery of a fluid inflation media and a slip-layered balloon (12) made up of a plurality of layers with a low-friction substance between the layers. The low-friction substance causes the layers to slide readily relative to one another, softening the balloon while maintaining its strength. Optionally, the balloon includes a plurality of slip-layered segments radially disposed about the balloon wall, and separated by lengthwise ridges joining the layers of each segment together. Also optionally, an elastic sleeve surrounds the balloon wall to improve refoldability of the balloon.
