Deployment system for an endoluminal device
First Claim
1. A deployment system for an endoluminal device comprising:
- an expandable endoluminal device mounted on a delivery catheter provided with an endo-prosthesis mounting member;
a removable sheath in the form of a continuous double-walled tube adapted to cover and constrain at least a portion of said endoluminal device in an introductory profile;
wherein said deployment system includes a deployment line integral with and extending from one wall of said double-walled tube to which tension can be applied to aid endoluminal device deployment;
wherein upon endoluminal device deployment, said double-walled tube progressively unrolls from around said endoluminal device through actuation of said deployment line to form removed sheath material;
wherein said removed sheath material begins to become converted to deployment line at a point where said removed sheath material breaks apart, separates, and converges into deployment line material in the form of an elongated filament; and
wherein said converged deployment line material is removed from said deployment system along with said deployment line.

Abstract
The present invention is directed to a deployment system for an endoluminal device. The deployment system includes a confining sheath placed around a compacted endoluminal device. A deployment line is provided in the system that is an integral extension of the sheath. As the deployment line is actuated, the sheath retracts from around the compacted endoluminal device. As the sheath retracts from around the endoluminal device, material from the sheath may be converted into deployment line. Once the sheath is retracted from around the compacted endoluminal device, the endoluminal device expands in configuration and repairs vascular or cardiac structures of an implant recipient. Any remaining sheath material is removed from the implantation site along with the deployment line. The deployment system also includes an endo-prosthesis mounting member placed between the endoluminal device and an underlying catheter. The endo-prosthesis mounting member serves to cushion and retain the endoluminal device when constrained by the sheath and may assist in expansion of the endoluminal device when unconstrained by the sheath.

19. A deployment system for an endoluminal device comprising:
-
an expandable endoluminal device placed over an endo-prosthesis mounting member and at least partially enclosed by a removable sheath; wherein said removable sheath comprises a polymeric material in the form of a continuous double thin-walled tube adapted to surround at least a portion of the expandable endoluminal device and constrain the expandable endoluminal device in an introductory profile on the endo-prosthesis mounting member; an extension of the double thin-walled tube in the form of a filamentous deployment line, wherein the deployment line extension is integral and continuous with the double thin-walled tube; and wherein upon actuation of the deployment line, the double thin-walled tube unrolls from the endoluminal device and converts from the double thin-walled tube to form to a single elongated deployment line filament. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39)
