Abstract
Abstract A synthetic liner is inserted into a blood vessel in the region of a treated stenosis. The liner is composed of a material resistant to the deposition of the fatty matter from the blood so that the build up of a new obstruction to blood flow is inhibited. The liner is tapered to generally conform to the taper or reduction in cross section of the artery in a downstream direction. The material is resilient and has elasticity compatible with the elasticity of the artery.

Claim 1
Independent Claim
85 words
The method of inhibiting recurrence of stenosis in the coronary arterial system in the region of a treated stenosis, comprising moving a thin-walled elastic liner substantially conforming to the internal blood vessel wall into a location within the stenotic blood vessel region with said liner disposed on a balloon of a catheter, expanding the balloon to force the liner into engagement with the blood vessel wall, deflating the catheter and removing the catheter from the blood vessel, leaving the liner in place in said location.
