Manufacturing review: the lot number was provided and the lot device history records were reviewed.
The lot met all release criteria.
There was nothing found to indicate there was a manufacturing related cause for this event.
This is the only complaint reported for this lot number and issue to date.
Visual/microscopic inspection: the sample was returned used.
The balloon appeared to have been previously inflated.
The proximal segment contained the hub and the strain relief.
The distal segment contained the rest of the catheter and the balloon.
No other anomalies were noted to the catheter.
Performance/functional evaluation: the strain relief was removed from the hub.
The catheter detachment underneath the strain relief was examined under magnification and the edges of the detachment were jagged.
The catheter detachment was located just distal to the y-hub.
Sanding marks were noted on the catheter at the point of the detachment.
No functional testing could be performed due to the condition in which the sample was returned (i.
E.
Catheter detachment).
Medical records review: medical records were not provided for review.
Image/photo review: images/photos were not provided for review.
Conclusion: the investigation is confirmed for a complete circumferential catheter shaft break just distal to the y-hub, which the user likely perceived as a damaged "coaxial stem".
It is unknown whether handling techniques by the user as they removed the catheter from the packaging or prepped the device may have contributed to the reported issue.
Based upon the available information a definitive root cause has not been determined.
Labeling review: the current ifu (instructions for use) states: precautions: carefully inspect the catheter prior to use to verify that catheter has not been damaged during shipment and that its size, shape, and condition are suitable for the procedure for which it is to be used.
Do not use if product damage is evident.
Use of the ultraverse 035 pta dilatation catheter: position the balloon relative to the lesion to be dilated, ensure the guidewire is in place, and inflate the balloon to the appropriate pressure.
