Официальное название
Prospective Multicenter Clinical Performance Study of a Single-use Large Channel Digital Pancreaticobiliary Scope (DPS) With Compatible Accessories
Обзор
This study plans to enroll up to 75 research subject who have a biliary disorder such as bile duct stones or intermediate biliary strictures. The purpose of this research is to assess whether the Dragonfly™ Pancreaticobiliary Scope functioned as intended in combination with the commercially available accessories during your scheduled endoscopy procedure. This includes achieving stone fragmentation of difficult biliary stone(s) while obtaining adequate tissue specimens for analysis. There will also be a Product performance evaluation as rated by the endoscopist operating the DPS System and evaluation of ergonomics and usability.
Вмешательства
- Устройство Dragonfly™ Digital Pancreaticobiliary System
Dragonfly™ Digital Pancreaticobiliary System is indicated for use in the direct visualization of the biliary and pancreatic ducts for diagnostic and therapeutic interventions during endoscopic procedures. DPS is a single-use device that serves as an access and delivery catheter used with a proprietary DDC. The DDC is intended to control auto-illumination, and process images from the DPS for diagnostic and therapeutic applications during endoscopic procedures in the pancreaticobiliary system incl
