SpyGlass™ DS II Direct Visualization System in physician's hands.

Managing complex stones with SpyGlass™ DS

Bile duct obstruction and gallbladder stone

Direct visualization for pancreaticobiliary stone removal  supports a physician's ability to clear the stone by using EHL to fragment the stone while directly validating that the stone was fully removed. In a study, stone removal with cholangioscopy has shown a 95% clearance rate and may reduce the need for more invasive and costly procedures, which may have a significant impact on patient outcomes and patient satisfaction.1
