Optimising performance in sphincterotomy and sphincteroplasty

Adding sphincteroplasty to stone extraction procedures is becoming more common for the treatment of large stones in the bile duct. StoneMasterV combines the two steps of sphincterotomy and sphincteroplasty into one endoscopic device, saving time by eliminating the need for device exchange and simplifying stone management. 

Difficult Biliary Stone Extraction

Current ESGE guidelines suggest performing endoscopic sphincterotomy followed by an endoscopic papillary large balloon dilation for the extraction of selected difficult biliary stones. This approach is considered to show similar post-ERCP pancreatitis rates, a lower bleeding and overall complications risk when compared to endoscopic sphincterotomy alone.*

  • Stable Knife Orientation - The pre-curved distal end of the StoneMasterV extrudes to a stable 11 o’clock position, reducing efforts in cannulation of the papilla and ensuring optimised cutting.

  • CleverCut Coating Enhances Safety - The CleverCut coating on the proximal end of the cutting wire minimizes the damage to the surrounding tissue, virtually eliminating any risk of electrical contact between the wire and endoscope.

  • Optimal Dilation of the Papilla - The integrated multi-sizing balloon is continuously adjustable to three controlled dilation diameters. The tapered balloon edges allow to have a clear endoscopic view through the balloon onto the dilated tissue.

  • Effortless Device Exchange - C-Channel-optimised StoneMasterV supports device exchange for short-wire or traditional over-the-wire techniques. It is designed for use in combination with the VisiGlide.
