Manufacturing review: a manufacturing review was conducted.The device history records were reviewed with special attention to the receiving inspection data, internal rejects history, and manufacturing controls.The lot met all test released criteria.There was nothing found to indicate there was a manufacturing related cause for this event.This is the only complaint that has been reported for this corporate lot number to date.Visual/microscopic inspection: the sample was returned.The balloon size for this product was printed on the balloon hub of the catheter and identified the returned sample as a 10mm x 40mm balloon.A complete circumferential catheter detachment was identified to the catheter.No other anomalies were noted to the strain relief or the y-hub.Functional/performance evaluation: the strain relief was removed from the y-hub.A complete circumferential catheter detachment was identified near the bifurcate, 2.0cm from the bifurcate.The catheter detachment was examined under microscopic magnification (10x) and the edges of the break were jagged.Sanding marks were noted on the catheter at the location of the break.Further functional testing could not be performed due to sample condition.Medical records review: medical records were not provided; therefore, a review could not be performed.Image/photo review: images/photos were not provided; therefore, a review could not be performed.Conclusion: the investigation was confirmed for a complete circumferential catheter detachment just distal to the y-hub.The investigation was inconclusive for difficult to insert, as functional testing could not be performed due to the poor sample condition.Additionally, the investigation was unconfirmed for kinked catheter, as no kinks were identified.Excessive sanding of the catheter under the strain relief was the root cause for the catheter detachment.It is possible the detachment contributed to the insertion issues.Corrective and preventative actions have been implemented, this lot is pre corrective action.Labeling review: the current ifu (instructions for use) states: warnings: when the catheter is exposed to the vascular system, it should be manipulated while under high quality fluoroscopic observation.Do not advance or retract the catheter unless the balloon is fully deflated.If resistance is met during manipulation, determine the cause of the resistance before proceeding.Applying excessive force to the catheter can result in tip or catheter breakage, catheter kink, or balloon separation.Precautions: if resistance is felt during post procedure withdrawal of the catheter through the introducer sheath/guide catheter, determine if contrast is trapped in the balloon with fluoroscopy.If contrast is present, push the balloon out of the introducer sheath/guide catheter and then completely evacuate the contrast before proceeding to withdraw the balloon.If resistance is still felt during post procedure withdrawal of the catheter, it is recommended to remove the balloon catheter and introducer sheath/guide catheter as a single unit.Potential adverse reactions the complications that may result from a peripheral balloon dilatation procedure include: additional intervention.Use of ultraverse 035 pta dilatation catheter: apply negative pressure to fully evacuate fluid from the balloon.Confirm that the balloon is fully deflated under fluoroscopy and that no contrast is left in the balloon.While maintaining negative pressure and the position of the guidewire, grasp the balloon catheter just outside the introducer sheath/guide catheter and withdraw the deflated dilatation catheter over the wire through the introducer sheath/guide catheter.Use of a gentle counterclockwise motion may be used to help facilitate catheter removal through the introducer sheath/guide catheter.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.
