Manufacturer Narrative
|
Date of event: date of event was approximated to 09/01/2019 as no event date was reported.Problem code 1504 captures the reportable event of balloon pinhole.Investigation result: a visual examination of the complaint device revealed the balloon was subjected to positive pressure and re-folded.Functional analysis was performed, a longitudinal tear was noted from approximately 30mm distal of the proximal balloon bond and extending approximately 9mm distally.No issues were noted on the balloon material, markerband, tip and shaft.This failure is likely due to an interaction between the user and device, or sample, that caused or contributed to the error.It is likely that the failure may be related to the balloon being pre-tested and the handling of the device during the procedure.Therefore, the most probable root cause is unintended use error caused or contributed to event.A review of the device history record (dhr) was performed and confirmed that this device met all material, assembly and performance specifications.A labeling review was performed and from the information available, this device was not used per the directions for use (dfu)/product label as the device was pre-inflated.
