1. An assembly for positioning a graft within a vasculature, which comprises:
- a) a guide wire having proximal and distal ends and a first attachment portions wherein the guide wire has a length between the ends sufficient to extend from an entry opening into the vasculature, past a treatment zone and out an exit opening from the vasculature;
b) a graft having a central lumen extending to proximal and distal graft ends; and
c) at least one string extending from each of the proximal and distal graft ends, wherein the at least one string extending from the distal graft end is connectable to the first attachment portion of the guide wire so that when the guide wire extends through the vasculature with the proximal end thereof extending out the entry opening and with the first attachment portion accessible from outside the vasculature adjacent to the entry opening, the at least one string extending from the distal graft end is connectable to the first attachment portion so that the guide wire is manipulatable to move the graft through the vasculature until the at least one string extending from the distal graft end and connected to the first attachment portion of the guide wire extends out the exit opening and the at least one string extending from the proximal graft end extends out the entry opening, and wherein the at least one string extending from the distal draft end is disconnectable from the first attachment portion of the guide wire to remove the guide wire from connection with the graft so that the graft is positionable to span the treatment zone by manipulation of the at least one string connected to each of the proximal and distal graft ends.

Abstract
An apparatus for engrafting a blood vessel comprising: a plurality of strings, a tubular graft having a central lumen, wherein the plurality of strings are removably attached to the tubular graft, the graft is removably positioned at least partially within a restraining means, such as a sheath introducer, a guide wire with an attachment means for attachment of the plurality of strings, one or more stents for deployment within the graft, and a means for deploying the stents within the graft.

22. An assembly for repairing an aneurysm within a vasculature, which comprises:
-
a) a guide wire having proximal and distal ends and a first attachment portion, wherein the guide wire has a length between the ends sufficient to extend from an entry opening into the vasculature, past a treatment zone and out an exit opening from the vasculature; b) an engrafting device having a central lumen extending to proximal and distal ends thereof; and c) at least one string extending from each of the proximal and distal ends of the engrafting device, wherein the at least one string extending from the distal end of the engrafting device is connectable to the first attachment portion of the guide wire so that when the guide wire extends through the vasculature with the proximal end thereof extending out the entry opening and with the first attachment portion accessible from outside the vasculature adjacent to the entry opening, the at least one string extending from the distal end of the engrafting device is connectable to the first attachment portion so that the guide wire is manipulable to move the engrafting device through the vasculature until the at least one string extending from the distal end of the engrafting device and connected to the first attachment portion of the guide wire extends out the exit opening and the at least one string extending from the proximal end of the engrafting device extends out the entry opening, and wherein the at least one string extending from the distal end of the engrafting device is disconnectable from the first attachment portion of the guide wire to remove the guide wire from connection with the engrafting device so that the engrafting device is positionable to span the aneurysm by manipulation of the at least one sting connected to each of the proximal and distal ends of the engrafting device.

23. An assembly for positioning a stent within a vasculature, which comprises:
-
a) a guide wire having proximal and distal ends and a first attachment portion, wherein the guide wire has a length between the ends sufficient to extend from an entry opening into the vasculature, past a treatment zone and out an exit opening from the vasculature; b) a stent having a central lumen extending to proximal and distal ends thereof; and c) at least one string extending from each of the proximal and distal ends of the stent, wherein the at least one string extending from the distal end of the stent is connectable to the first attachment portion of the guide wire so that when the guide wire extends through the vasculature with the proximal end thereof extending out the entry opening and with the first attachment portion accessible from outside the vasculature adjacent to the entry opening, the at least one string extending from the distal end of the stent is connectable to the first attachment portion so that the guide wire is manipulable to move the stent through the vasculature until the at least one string extending from the distal end of the stent and connected to the first attachment portion of the guide wire extends out the exit opening and the at least one string extending from the proximal end of the stent extends out the entry opening, and wherein the at least one string extending from the distal end of the stent is disconnectable from the first attachment portion of the guide wire to remove the guide wire from connection with the stent so that the stent is positionable in the vasculature at a desired location by manipulation of the at least one string connected to each of the proximal and distal ends of the stent.
