SX-ELLA biodegradable biodegradable esophageal stent. The stent is flared at both ends to reduce the risk of migration and is fitted with radiopaque markers at the midpoint and at the ends to enable precise stent positioning under fluoroscopic control. Because of reduced long-term elasticity, the stent is supplied separate from the delivery system and needs to be manually loaded just before the implantation procedure (see manufacturer’s “Instructions for Use”).
