It was reported that the pta balloon catheter allegedly would not inflate during the first inflation.There was no reported retraction difficulty through the sheath.It was further reported that upon removal, an alleged hole was identified on the proximal side of the balloon catheter near the hub.Reportedly, another balloon catheter was used to complete the procedure.There was no reported impact or consequence to the patient.

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.The balloon appeared to have been previously inflated.No anomalies were noted to the strain relief or the y-hub.Functional/performance evaluation: the patency was tested using a 0.035¿ guidewire and it passed without issue.The inflation hub was connected to a inflation device and the balloon inflated with water.During inflation, water was observed leaking out of the distal end of the strain relief.The strain relief was removed and a partial circumferential break was found on the catheter, located at the distal end of the y-hub.The catheter break was examined under magnification and the edges of the break were jagged.Sanding marks were present at the location of the catheter shaft break.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 partial circumferential catheter shaft break just distal to the y-hub, which resulted in the inability to inflate the balloon.Excessive sanding of the catheter under the strain relief is the root cause for the catheter detachment.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.(b)(4).The information provided by bard represents all of the known information at this time.Despite good faith efforts to obtain additional information, the complainant / reporter was unable or unwilling to provide any further patient, product, or procedural details to bard.
