Apparatus and method for dilating a lumen and for inserting an intraluminal graft

DETAILED DESCRIPTION The invention herein provides an intraluminal graft, an insertion device for deploying the graft, and a method for deploying the graft in a lumen.
The intraluminal graft includes a generally tubular, biocompatible body and multiple anchors attached to the interior surface of the body with barbs extending beyond the distal end of the body for penetrating a lumen wall.
A self-expanding stent is positioned adjacent to the interior surface of the body.
The self-expanding stent can be an engine having an engine coil.
One end of the engine coil is attached to the body, and the other end of the engine coil is sized and configured for attachment to an insertion device.
It is preferred that the engine include an engine lock and an engine fastener.
The engine fastener can movably fasten the engine lock to the other end of the engine coil.
In addition, the engine lock is preferred to be adapted to lockingly receive an end of the main anchor.
It is further preferred that the engine coil includes multiple spaced apart tabs that are biased towards the longitudinal axis of the engine coil, with each of tabs being positioned to retain one portion of the engine coil in a preselected alignment with another portion of the engine coil.
Also, the engine coil can be a preselected diameter when deployed, such as between about 20 millimeters and about 35 millimeters.
In general, the engine coil is adapted to exert a selectable radial force upon the interior surface of the graft body.
It is also preferred that one of the anchors is a main anchor that is attached to the interior surface of the graft body.
Each of the anchors can have multiple, barbed tines thereon.
One embodiment of the tines includes a saw-tooth configuration.
It is preferred that at least a portion of the graft body be furcated, thereby forming a distal tube and multiple proximal tubes.
It is also preferred that at least one of the proximal tubes have a loop attached thereto, the loop being suitable for snaring and manipulation thereof
