The device history records were reviewed with special attention to the raw materials, subassemblies, manufacturing process and quality control testing.This lot met all release criteria.There was nothing found to indicate there was a manufacturing related cause for this event.This is the only event reported to date for this lot number and failure mode.Visual inspection: the sample was returned with the product label.The balloon size for this product was printed on the balloon hub of the catheter and identified the returned sample as a 6mm x 250mm balloon.The catheter was returned inserted through the sheath, with the distal tip and part of the balloon visibly protruding 0.9cm from the distal end of the sheath.A kink was noted approximately 4.0cm from the distal end of the distal tip.The balloon protruding from the sheath was slightly prolapsed over the catheter distal tip, indicating sheath-related retraction issues.Additionally, the devices were examined under microscopic magnification (10x) and the distal tip of the sheath was found to be flared.Functional/performance evaluation: the balloon was unable to be removed from the introducer sheath.An in-house 0.035" guidewire was unable to be inserted completely through the device, due to the catheter being stuck in the sheath.No further functional testing could be completed due to the poor sample condition.Medical records review: medical records were not provided for review.Image/photo review: images/photos were not provided for review.Conclusion: the device was returned stuck within the customer's introducer sheath.The device was unable to be removed from the sheath, and the balloon was found to be prolapsed over the distal tip.Additionally, the distal end of the sheath was found to be flared outward.Based on the returned sample condition, the investigation can be confirmed for sheath-related retraction issues.The definitive root cause for the identified sheath-related retraction issues could not be determined based upon the available information.It was unknown if patient and/or procedural issues contributed to the reported event.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.
