Abstract

An endoluminal prosthesis system deployable in a region of a patient'"'"'s vasculature having one or more branch vessels, having a main graft body having a first opening in a wall portion of the main graft body and a pre-loaded guidewire positioned inside the main graft body and advanced through the first opening. One or more branch grafts can be attached to the main graft body to cover one or more openings in the main graft body.

Claims

1. An endoluminal prosthesis system comprising:

a delivery catheter having a flexible catheter body and a proximal and a distal end;

an endoluminal prosthesis comprising a main graft body having a lumen axially therethrough and a first lateral opening in wall portion of the main graft body, the first lateral opening being in communication with the lumen; and

a hollow guidewire advanced from a proximal end of the catheter body through at least a portion of the catheter body, through at least a portion of the lumen of the main graft body, and through the first lateral opening in the wall portion of the main graft body when the endoluminal prosthesis is in a collapsed, pre-delivery state within the catheter body.

2. The endoluminal prosthesis system of claim 1, comprising a second lateral opening in the wall portion of the main graft body, the second lateral opening being in communication with the lumen.

3. The endoluminal prosthesis system of claim 2, comprising a first branch graft attached the main branch graft body so as to surround the first lateral opening in the main graft body and a second branch graft attached the main branch graft body so as to surround the second lateral opening in the main graft body.

4. The endoluminal prosthesis system of claim 3, wherein the first and second branch grafts are attached to the first main graft body are expandable with a bare or covered metal stent.

5. The endoluminal prosthesis system of claim 1, wherein the main graft body comprises one or more cutouts in an end portion thereof.

6. The endoluminal prosthesis system of claim 1, further comprising a second endoluminal prosthesis positioned adjacent to or overlapping at least a portion of the endoluminal prosthesis.

7. The endoluminal prosthesis system of claim 1, wherein the main graft body is a bifurcated endoluminal prosthesis.

8. The endoluminal prosthesis system of claim 1, wherein the endoluminal prosthesis has at least one radiopaque suture or marker supported thereby.

9. The endoluminal prosthesis system of claim 1, wherein the catheter body has an inner core and an outer sleeve, the inner core and outer sleeve being slidable relative to one another.

10. The endoluminal prosthesis system of claim 1, wherein at least a portion of the guide wire extends between an outside surface of the main body graft and the catheter body when the endoluminal prosthesis is in a collapsed, pre-delivery state within the catheter body.

20. A method of deploying the prosthesis of claim 1 in a portion of a patient'"'"'s blood vessel having at least a first branch blood vessel using the delivery catheter of claim 1, comprising:

advancing a guidewire through a first puncture hole in the patient'"'"'s body, into the patient'"'"'s blood vessel, and into the first branch blood vessel;

advancing the delivery catheter into the first puncture hole in the patient'"'"'s body, wherein;

the delivery catheter supports the prosthesis in a collapsed state; and

advancing the delivery catheter through the first puncture hole so that the hollow guidewire is advanced over the guidewire while the prosthesis is in the collapsed, pre-delivery state; and

deploying the prosthesis within the patient'"'"'s blood vessel.

21. The method of deploying the prosthesis of claim 20, further comprising approximately aligning the first opening in the prosthesis with an ostium of the first branch blood vessel by advancing the delivery catheter through the first puncture hole so that the hollow guidewire is advanced over the guidewire while the prosthesis is in the collapsed, pre-delivery state.

22. The method of deploying the prosthesis of claim 20, wherein the hollow guidewire tube prepositioned within the prosthesis passes through a main lumen of the prosthesis, through a first opening positioned laterally through the wall of the prosthesis, and out past a distal end of an outer sheath of the delivery catheter when the prosthesis is in a collapsed, pre-delivery state within the delivery catheter.

11. An endoluminal prosthesis system comprising:

a delivery catheter having a flexible catheter body and a proximal and a distal end;

an endoluminal prosthesis comprising a main graft body having a lumen axially therethrough and a first lateral opening in a wall portion of the main graft body, the first lateral opening being in communication with the lumen; and

a pre-loaded guidewire positioned through at least a portion of the lumen of the main graft body and through the first lateral opening in the wall portion of the main graft body when the main graft body is in a collapsed, pre-delivery state within the catheter body.

12. The endoluminal prosthesis of claim 11, further comprising a hollow sleeve adapted to surround the pre-loaded guidewire and adapted to be advanced through at least a portion of the first lumen of the first main graft body and through the first lateral opening of the first main graft body.

13. The endoluminal prosthesis system of claim 11, comprising a second lateral opening in the wall portion of the main graft body, the second lateral opening being in communication with the lumen.

14. The endoluminal prosthesis system of claim 11, comprising a first branch graft attached the main branch graft body so as to surround the first lateral opening in the main graft body and a second branch graft attached the main branch graft body so as to surround the second lateral opening in the main graft body.

15. The endoluminal prosthesis system of claim 14, wherein the first and second branch grafts attached to the first main graft body are expandable with a bare or covered metal stent.

16. The endoluminal prosthesis system of claim 11, wherein the main graft body is a bifurcated endoluminal prosthesis.

17. The endoluminal prosthesis system of claim 11, wherein the endoluminal prosthesis has at least one radiopaque suture or marker supported thereby.

18. The endoluminal prosthesis system of claim 11, wherein the catheter body has an inner core and an outer sleeve, the inner core and outer sleeve being slidable relative to one another.

19. The endoluminal prosthesis system of claim 11, wherein at least a portion of the guide wire extends between an outside surface of the main body graft and the catheter body when the main graft body is in a collapsed, pre-delivery state within the catheter body.
