Abstract

See full text

A catheter arrangement including an inflatable variable diameter element and a linearly expandable spring-like liner retained in a compressed state behind the inflatable element and means to change the diameter of the inflatable element. The expandable liner is transported to desired location in its compressed state and is released and allowed to expand after a successful P.T.A.P. operation when the balloon is deflated and evacuated creating a diameter of the balloon which is smaller than that of the expandable liner. The catheter is then allowed to be removed and withdrawn leaving the liner deployed and implanted within the blood vessel.
