Abstract

The present invention relates to an apparatus for deploying and endoluminal prosthesis. The apparatus includes a flexible compressible push rod that allows the catheter to be easily maneuvered through tortuous vessels while providing sufficient deployment force.

Claims

1. An endoluminal prosthesis comprising:

a graft;

means for attaching the graft within a vessel; and

medical grade expandable foam cuffs that are independent of and displaced from the attachment means and positioned surrounding the graft.

2. The endoluminal prosthesis of claim 1, wherein said cuffs include living tissue cells.

3. The endoluminal prosthesis of claim 1, wherein said cuffs include fetal endothelial cells.

4. The endoluminal prosthesis of claim 1, wherein said cuffs include smooth muscle cells.

5. The endoluminal prosthesis of claim 1, wherein said cuffs include glioma growth factor.

6. The endoluminal prosthesis of claim 1 further comprising:

a light actuated cryo precipitate fibrin glue disposed on an exterior surface of said graft.

7. An endoluminal prosthesis comprising:

a graft; and

a plurality of packets containing a biocompatible tissue adhesive, wherein said packets are fixed to an exterior surface of said graft.

8. The endoluminal prosthesis of claim 7, wherein said packets are formed of a light degradable polymer.

9. The endoluminal prosthesis of claim 7, wherein said packets are constructed of photosensitive polyurethane.

10. The endoluminal prosthesis of claim 7, wherein said biocompatible tissue adhesive is fibrin glue.

11. The endoluminal prosthesis of claim 7, wherein said biocompatible tissue adhesive is isobutyl 2-cyanoacrylate.

12. An endoluminal prosthesis comprising:

a graft having a proximal end and a distal end;

means for attaching said graft within a vessel, wherein said means for attaching secures at least said proximal end of said graft within the vessel; and

a wire anchor spring including a proximal spring portion and a distal spring portion connected to said proximal spring portion by an axially extending connecting bar, wherein said proximal spring portion is positioned remotely of said proximal end of said graft and said distal spring portion is positioned within said graft distally of said means for attaching said proximal end of said graft to the vessel.
