1. A vascular implant comprising:
- (a) a scaffold defining an interior volume, a first end, and an opposite second end;
said scaffold having an exterior surface and an interior surface, said scaffold interior surface defining a lumen, said lumen including a longitudinal axis, said longitudinal axis including a bend between said first end and said second end;
(i) said interior surface lining said interior volume; and
(b) a tubing in covering relation to said scaffold;
(i) said scaffold interior surface being completely covered by said tubing from said first end to said second end;
(ii) said scaffold exterior surface being completely covered by said tubing from said first end to said second end, wherein said tubing includes a portion in extension away from and/or remote from said scaffold, wherein said tubing is folded over one of said first and second ends of the scaffold.

Abstract
A vascular implant includes a scaffold and a tubing in covering relating to the scaffold. Preferably, the tubing completely covers or encases the scaffold interior surface and exterior surface to leave no portion of the scaffold exposed. Methods for constructing includes pulling tubing through a scaffold and folding at least a portion of the tubing over at least one of the ends of the scaffold. Methods for using an implant include performing coronary vessel bypass procedures or forming blood flow paths in a blood vessel utilizing constructions described herein.

10. A method of making a vascular implant;
- the method comprising;
(a) providing a tubing having first and second ends;
(b) providing a scaffold having an exterior surface;
an interior surface;
an interior volume;
a scaffold first end; and
an opposite scaffold second end, said scaffold interior surface defining a lumen, said lumen including a longitudinal axis, said longitudinal axis including a bend between said scaffold first end and said scaffold second end;
(c) completely covering the scaffold interior surface from the scaffold first end to the scaffold second end with the tubing; and
(d) completely covering the scaffold exterior surface from the scaffold first end to the scaffold second end with the tubing;

17. A method for performing a coronary vessel bypass procedure for supplementing a flow of blood to a coronary vessel;
- the method comprising;
(a) forming a blood flow path from a heart chamber directly to the coronary vessel at a site in the vessel positioned between an obstruction in the vessel and tissue of the heart to be supplied with blood by the vessel;
(i) the step of forming including placing a conduit in a heart wall between the chamber and the vessel with a first end of the conduit protruding into the chamber and protruding beyond an interior surface of the heart wall;
the conduit having a second end;
(A) the conduit including a tubing completely lining an interior surface of the conduit between the first and second ends, and completely lining an exterior surface of the conduit between the first and second ends, said interior surface of the conduit defining a lumen, said lumen including a longitudinal axis, said longitudinal axis including a bend between said first end and said second end, wherein said tubing includes a portion in extension away from and/or remote from said conduit wherein said tubing is folded over one of said first and second ends of the conduit.
