AQUABEAM ROBOTIC SYSTEM

Additional Manufacturer Narrative

THE AQUABEAM ROBOTIC SYSTEM IS A REUSABLE DEVICE; THEREFORE, IT IS STILL CURRENTLY IN POSSESSION OF THE USER FACILITY. THE INVESTIGATION OF THIS EVENT CONSISTED OF A REVIEW OF THE TREATMENT LOG FILES, DEVICE HISTORY RECORD (DHR), INSTRUCTIONS FOR USE (IFU), AND PROCEPT'S RISK DOCUMENTATION. THE AQUABEAM ROBOTIC SYSTEM'S TREATMENT LOG FILES WERE REVIEWED. THE REVIEW OF THE TREATMENT LOG FILES REVEALED THAT THE AQUABEAM ROBOTIC SYSTEM FUNCTIONED AS INTENDED, AS NO MALFUNCTION WAS OBSERVED DURING AQUABLATION THERAPY. A REVIEW OF THE DEVICE HISTORY RECORD (DHR) FOR AB2000-B/SERIAL NUMBER (B)(6) WAS CONDUCTED, WHICH CONFIRMED THAT THERE WERE NO NON-CONFORMANCES, FAILURES, DISCREPANCIES, OR MISSED STEPS DURING THE MANUFACTURING PROCESS THAT COULD BE RELATED TO THE REPORTED EVENT. THE REVIEW INDICATED THAT THE SYSTEM MET ALL DESIGN AND MANUFACTURING SPECIFICATIONS WHEN RELEASED FOR DISTRIBUTION. THE AQUABEAM ROBOTIC SYSTEM'S INSTRUCTIONS FOR USE (IFU), IFU0101-00, REV. E, WAS REVIEWED. ALTHOUGH THE AQUABEAM ROBOTIC SYSTEM'S LABELING DOES NOT SPECIFICALLY MENTION DAMAGE TO URETERAL ORIFICES, PROCEPT'S RISK MANAGEMENT DOCUMENTATION INCLUDES DAMAGE TO URETERAL ORIFICES AS A CLINICAL EFFECT OF AQUABLATION THERAPY. THE AQUABEAM ROBOTIC SYSTEM IS A REUSABLE DEVICE; THEREFORE, IT IS STILL CURRENTLY IN POSSESSION OF THE USER FACILITY. THE TREATING SURGEON INADVERTENTLY HIT THE PATIENT'S URETERAL ORIFICES (UO) AND STATED THAT IT WAS LIKELY DUE TO THE PATIENT'S ATYPICAL ANATOMY. THE PATIENT'S LEFT URETERAL ORIFICE (UO) WAS THEN STENTED. ALTHOUGH THE AQUABEAM ROBOTIC SYSTEM'S LABELING DOES NOT SPECIFICALLY MENTION DAMAGE TO URETERAL ORIFICES, PROCEPT'S RISK MANAGEMENT DOCUMENTATION INCLUDES DAMAGE TO URETERAL ORIFICES AS A CLINICAL EFFECT OF AQUABLATION THERAPY. BASED ON THE INFORMATION RECEIVED, PLUS A REVIEW OF THE TREATMENT LOG FILES, DHR, IFU, AND PROCEPT'S RISK DOCUMENTATION, THE EVENT IS CONSIDERED NOT TO BE DEVICE RELATED. SUBMISSION OF THIS REPORT DOES NOT CONSTITUTE AN ADMISSION THAT THE MANUFACTURER'S PRODUCT CAUSED OR CONTRIBUTED TO THE EVENT.

Description of Event or Problem

A MALE PATIENT UNDERWENT AQUABLATION THERAPY FOR SYMPTOMATIC BENIGN PROSTATIC HYPERPLASIA (BPH). PROCEPT BIOROBOTICS (PROCEPT) BECAME AWARE THAT DURING AQUABLATION THERAPY, THE TREATING SURGEON BELIEVED THE PATIENT'S URETERAL ORIFICES (UOS) WERE CONTACTED BY THE WATERJET DUE TO THE PATIENT¿S ATYPICAL ANATOMY. FOLLOWING THE PROCEDURE, THE PATIENT¿S LEFT URETERAL ORIFICE REQUIRED PLACEMENT OF A STENT. THE TREATING PHYSICIAN ATTRIBUTED THE EVENT TO THE PATIENT¿S ANATOMY, AND NOT TO AQUABLATION THERAPY. NO MALFUNCTION OF THE AQUABEAM ROBOTIC SYSTEM WAS REPORTED.
