1. A stent deployment system, comprising:
- a handle,a flexible sheath coupled to the handle,a flexible tube extending into the handle and through the sheath about a longitudinal axis,a tapered flexible extension coupled to the flexible tube, the tapered extension having a continuous reverse taper from a maximum diameter of the tapered flexible extension to an outer diameter of the flexible tube, the reverse taper facing toward the handle,an endoluminal prosthesis disposed about the flexible tube, having a proximal end and a distal end, anda distally advanceable thrust block coupled to and circumferentially surrounding the flexible tube, the thrust block disposed a longitudinal distance away from the proximal end of said prosthesis, providing tactile feedback to an operator when contact between the thrust block and said prosthesis is made after distal movement of the thrust block.

Abstract
A stent deployment system includes a handle and a flexible sheath coupled the handle. A flexible tube extends from the handle through the sheath. A tapered flexible extension is coupled to the flexible tube, the tapered flexible extension has a taper angle of between about 5 degrees and 15 degrees towards the handle. A bead of adhesive can be supplied at an end of the tapered flexible extension. A thrust block is coupled to the flexible tube, and an endoluminal prosthesis is positioned around the flexible tube between the thrust block and the tapered flexible extension with a space situated between the endoluminal prosthesis and the thrust block.

6. A stent deployment system, comprising:
-
a handle, a flexible sheath coupled to the handle, a flexible tube extending from the handle and through the sheath about a longitudinal axis; a tapered flexible extension coupled to the flexible tube, the tapered flexible extension having a transition to define a maximum diameter of the tapered flexible extension and a continuous reverse taper from the maximum diameter of the tapered flexible extension to an outer diameter of the flexible tube, where the reverse taper faces toward the handle and comprises an angle of between five degrees and fifteen degrees relative to the longitudinal axis, a distally advanceable thrust block coupled to and circumferentially surrounding the flexible tube, and an endoluminal prosthesis positioned coaxial with the flexible tube between the thrust block and the tapered flexible extension, said prosthesis spaced a longitudinal distance away from the thrust block, where the longitudinal distance is sufficient to provide tactile feedback to an operator when contact between the thrust block and said prosthesis is made after distal movement of the thrust block and before deployment of said prosthesis. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14)
