Patent ID: 7556641

Claim:
A deployment system for an endoluminal device comprising: an expandable endoluminal device mounted on a distal end of 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; wherein said converged deployment line material is removed from said deployment system along with said deployment line; wherein said deployment line is attached to an actuator at a proximal end of said catheter tube, wherein said actuator is coupled to a means in fluid communication with a lumen of said endoprosthesis mounting member for expanding said endoprosthesis mounting member, whereby said endoprosthesis mounting member is expanded simultaneously with unrolling of said overlying sheath from said expandable medical device.
