Manufacturing review: the lot number has been provided and the lot device history records have been 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 balloon guard and stylet were returned in their initial positions on the balloon.The balloon guard and stylet were removed from the catheter during while taking pictures during the decontamination process.The hub indicates 6.0mm x 220mm x 130cm.No anomalies were noted to the balloon or along the length of the catheter.The balloon was examined under microscopic magnification and the hydrophilic coating on the balloon was not uniform throughout the length of the balloon.Functional/performance evaluation: the patency of the guidewire lumen was tested using an in-house 0.018" guidewire and it passed without issue.The inflation hub was connected to an inflation device and the balloon was inflated to nominal pressure.The hydrophilic coating on the balloon was not uniform throughout the length of the balloon.No strings of hydrophilic coating were observed coming off the tip of the balloon.Medical records/image/photo review: no medical records or medical images have been made available to the manufacturer.Conclusion: the device was returned.The investigation is unconfirmed for foreign material present in the device, as the material present on the balloon was the hydrophilic coating and was not foreign to the device.The reported event details of strings of hydrophilic coating coming off the balloon and the presence of blood on the returned balloon suggests that the user may have activated the hydrophilic coating on the balloon.However, the root cause for the reported event is unknown.The condition of the returned balloon would have met the acceptance criteria at the manufacturing site, as the uniformity of the hydrophilic coating was only visible under microscopic magnification.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.In order to activate the hydrophilic coating, it is recommended to wet the ultraverse catheter with sterile saline solution immediately prior to its insertion in the body.Dilatation catheter preparation: remove catheter from package.Verify the balloon size is suitable for the procedure and the selected accessories accommodate the catheter as labeled.Remove the balloon guard and stylet by grasping the balloon catheter just proximal to the balloon and with the other hand, gently grasp the balloon protector and slide distally off of the balloon catheter.(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.
