  • esophageal-stent2


A novel ‘‘anchoring flap’’ (FCSEMS-AF) system made of four flaps in the proximal end to prevent anti-migration. One proximal lasso with gold marker is a cutting-edge advance in therapeutic endoscopy for benign biliary diseases as inversion retrieval.

Indications for use (Intended use)

The device is indicated for palliative treatment of bile duct malignant and/or benign strictures.

Clinical Study, B. Mangiavillano., et al1
Clinical Study B. Mangiavillano., et al1 Do Hyun Park, et al2
Migration Rate 3.3% (n=1 of 32) One at 125 days after placement 0% (n=22)
Successful Removal Rate 93.7% (n=30 of 32) One of the two patients in whom stent removal was not attempted died on day 122 after stent placement from underlying cardiovascular disease. The leak had clinically closed, and the abdominal drain had been removed. One patient was lost to follow-up 100% (n=22%)
