Encased implant and methods

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.

2. A vascular implant according to claim 1 wherein:

(a) said tubing comprises first and second ends and at least a first fold;

(i) said first fold covering said scaffold first end.

3. A vascular implant according to claim 2 wherein:

(a) said tubing first end is adjacent to and against said scaffold second end.

4. A vascular implant according to claim 1 wherein:

(a) said tubing includes a first end and a second end;

(i) said tubing second end forming an end of said extension remote from said scaffold.

5. A vascular implant according to claim 4 wherein:

(a) said scaffold is L-shaped.

6. A vascular implant according to claim 1 wherein:

(a) said tubing comprises expanded polytetrafluoroethylene.

7. A vascular implant according to claim 1 wherein:

(a) said scaffold comprises titanium or stainless steel.

8. A vascular implant according to claim 1 wherein:

(a) said scaffold comprises an impermeable tube.

9. A vascular implant according to claim 1 wherein:

(a) said scaffold comprises an impermeable mesh.

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;

wherein the vascular implant includes a portion of the tubing 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.

11. A method according to claim 10 further including:

(a) after said step of providing a scaffold, inserting the tubing through the interior volume of the scaffold; and

(b) folding the tubing over at least the first end of the scaffold from the interior surface of the scaffold to the exterior surface of the scaffold.

12. A method according to claim 11 further including:

(a) after said step of folding, securing the tubing to the scaffold.

13. A method according to 12 wherein:

(a) said step of securing includes securing the tubing first end adjacent to and against the scaffold second end on the exterior surface of the scaffold.

14. A method according to claim 10 wherein:

(a) said tubing includes a first end and a second end;

(b) said step of inserting the tubing includes inserting only a portion of the tubing into the scaffold interior volume and leaving a remaining portion of the tubing in extension from the scaffold;

(i) the tubing second end forming an end of the remaining portion remote from the scaffold.

15. A method according to claim 14 wherein:

(a) said step of providing a scaffold includes providing an L-shaped scaffold.

16. A method according to claim 10 further including:

(a) securing the tubing to the scaffold by bonding; the bonding including at least one of mechanical bond, chemical bond, and thermal bond.

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.
