An apparatus for correcting narrowing of a fluid vessel of the body comprising a catheter, for insertion into the blood vessel at a location remote from a region of narrowing, and a fluid vessel liner. The liner is comprised of a radially resiliently compressible tube having an elongated split along one side thereof. The edges of the sides of the liner on each side of the split overlap each other. The liner is contained within the catheter adjacent a tip of the catheter in a compressed condition. The catheter is constructed for expulsion of the liner from the catheter forward of the catheter at the region of narrowing, thereby facilitating expansion of the tube to a natural expanded condition so as to support the blood vessel from the interior to the diameter of the tube in its naturally expanded diameter. |
