Event Description

It was reported to boston scientific corporation that a nephromax high pressure nephrostomy balloon catheter was used in the right kidney during a percutaneous nephrolithotomy (pnl) procedure performed on (b)(6) 2022.During the procedure, the balloon would not inflate above 8 atm.The device was then removed, and the procedure was completed with another nephromax high pressure nephrostomy balloon catheter.There were no patient complications reported as a result of this event.This event has been deemed a reportable event based on the investigation finding of balloon pinhole.

Manufacturer Narrative

(b)(4).Investigation result: a visual examination of the returned nephromax balloon was analyzed, and a visual evaluation noted that the balloon was not folded which indicates that the balloon was subjected to positive pressure.Functional evaluation was performed by attaching the device into an encore inflation unit, and it was found that the balloon had a pinhole leak located at the proximal of the distal markerband.A visual and tactile analysis revealed that there were no problems found to the shaft, markerbands and the tip of the device.The reported event of balloon would not inflate was confirmed.It is possible that the interaction between the device and the kidney stone could have affected the device performance and its integrity, leading to the presence of a pinhole in the balloon material.Therefore, the most probable cause of the reported event is adverse event related to patient condition.A review of the manufacturing documentation for this device revealed that no anomalies or deviations related to the event occurred during manufacturing.A labeling review was performed and from the information available, this device was used per the instructions for use (ifu)/product label.
