This knitted nitinol stent offers a combination of flexibility and radial force to gradually expand within the esophageal lumen over 24–72 hours, relieving obstruction while minimizing patient discomfort. Its full silicone covering resists tumor ingrowth, seals concurrent fistulas, and helps reduce food impaction. Progressive step flared ends enhance anchorage and reduce migration risk in malignant or benign strictures. A Teflon-coated removal suture allows repositioning or retrieval during initial placement, and the device is MRI-conditional.
