Abstract

A radially self-expanding stent particularly suited for treating esophageal strictures, 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 the medial region, but the cuffs are not coated and retain their open weave construction. As a result, the cuffs remain particularly well suited to immediately contact esophageal wall tissue and resist stent migration, while the silicone coated medial region provides a barrier to tumor ingrowth, and has an enhanced radial restoring force to maintain an open passage-way in the esophagus. A deployment device for the stent includes an interior catheter surrounded by the stent and having an esophageal dilation feature, along with an exterior catheter that radially compresses the stent. A low durometer sleeve, fixed to the interior tube and in surface engagement with the compressed stent, tends to fix the axial position of the stent relative to the interior catheter whenever the exterior catheter is moved axially relative to the inner catheter. Consequently, precision in stent placement and the ability to recapture a partially deployed stent are enhanced.
