The lot number was provided and the lot device history records were reviewed.There was nothing found to indicate there was a manufacturing related cause for this event.The lot met all release criteria.Visual inspection: the sample was returned.The distal end of the balloon was partially prolapsed over the distal tip and was protruding out the distal end of the introducer sheath.The proximal end of the balloon bond was protruding out the proximal hub of the introducer sheath.A complete circumferential outer catheter break was noted at the proximal balloon glue joint.Stretching of the outer catheter was noted just proximal to the break.The glue bullet was located just proximal to the proximal balloon glue joint and was still present on the polyimide.This will be considered an incidental finding, as the break at the proximal balloon glue joint combined with excessive force may have contributed to the balloon becoming lodged inside the catheter shaft.It is unknown whether the glue bullet was lodged within the shaft during the deflation attempts.The outer diameter of the glue bullet could not be measured, as it was loose on the polyimide.The distal end of the sheath was examined and found the edge of the sheath tip was severely flared out, indicating retraction issues.The proximal end of the sheath was severely bunched, indicating retraction issues.Functional/performance evaluation: an attempt was made to retract the catheter through the sheath, but was unsuccessful.The balloon was able to be advanced through the sheath with resistance.Upon removal, it was noted that there was no fiber disturbance present on the balloon.Medical records & image/photo review: no medical records or images/photos were provided; therefore, a review could not be performed.Conclusion: the investigation is inconclusive for deflation issues, as the balloon was unable to be functionally tested due to the condition of the returned sample (i.E.Break at balloon glue joint).The investigation is confirmed for retraction problems and a break, as the balloon was unable to be removed from the sheath and an outer catheter break was present at the proximal balloon glue joint.The root cause for the deflation issues is unknown.Labeling review: specific warnings, precautions and directions for use of the conquest pta dilatation catheter are included in the current instructions for use (ifu).
