Papillary Balloon Dilation


The StoneMasterV combines sphincterotomy and papillary dilation into a single endoscopic device, improving efficiency by eliminating the need for device exchange, and simplifying biliary duct stone management.


Key Benefits

Endoscopic sphincterotomy plus endoscopic papillary dilation produces a higher rate of success and fewer complications when removing stones equal to or greater than 12mm.1,2 The 2019 American Society for Gastrointestinal Endoscopy (ASGE) guideline on the role of endoscopy in the evaluation and management of choledocholithiasis suggests performing sphincterotomy with endoscopic papillary large balloon dilation instead of sphincterotomy alone in patients with large bile duct stones. 3

Other Benefits Include:

  • Optimized Dilation: The 4mm length balloon provides positional stability and inflates to 3 controlled dilation diameters 
  • Short-wire design: Short wire compatibility to suit physician technique and enable use a guidewire lock at the biopsy port.
  • Stable Knife Orientation: The pre-curved distal end StoneMasterV extrudes to a stable 11 o'clock orientation, assisting with cannulation of the papilla and assuring optimized cutting.
