A radially self-expanding stent having multiple layers includes a medial region and proximal and distal cuffs having diameters greater than the medial region diameter when the stent is in the relaxed state. A silicone coating circumscribes at least the medial region of the stent. A deployment device for the stent includes an inner tube surrounded by the stent along with an outer tube that radially compresses the stent. A low durometer sleeve, fixed to the inner tube and in surface engagement with the compressed stent, tends to fix the axial position of the stent relative to the inner tube whenever the outer tube is moved axially relative to the inner tube. Consequently, precision in stent placement and the ability to recapture a partially deployed stent are enhanced.
