Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Interventional Group

Group Type EXPERIMENTAL

Dragonfly™ Digital Pancreaticobiliary System

Intervention Type DEVICE

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 including the hepatic ducts.

Inclusion Criteria

1. Provision to sign and date the consent form;
2. Adult patients ≥ 21 years old;
3. Any patient who is required to undergo endoscopic retrograde cholangiopancreatography (ERCP) procedure with the clinical need to perform cholangioscopy for:

2. Failed biliary stone extraction with conventional techniques.
4. Willing and able to follow study procedures and comply with study follow-up.

Exclusion Criteria

1. Pregnancy or lactation;
2. Surgically or physiologically altered GI anatomy that precludes advancement of the duodenoscope for biliary cannulation;
3. Patients on anti-coagulants and anti-platelet medications that cannot be withheld pre-procedure, except for aspirin, 81mg;
4. Coagulopathy (INR \> 1.8) or thrombocytopenia (Platelets \< 50,000) that is not correctable and felt to be a contraindication to proceeding with biopsy or lithotripsy per the treating endoscopist;
5. Active suppurative cholangitis with evidence of purulent drainage at the time of papilla visualization;
6. Patients who are not candidates for anesthesia to permit ERCP.
