This report is related to medwatch #9616099-2021-04223, 9616099-2021-04224, and 9616099-2021-04225.Complaint conclusion: when performing a shunt procedure, the balloon of three (3) 5mm x 4mm 80cm powerflex extreme percutaneous transluminal angioplasty (pta) balloon catheters were inflated; however, the balloons were blown, and the rated burst pressure (rbp) was not raised.¿as the balloon contracts in the state, the phenomenon of falling out continuously occurred, so a request from the hospital to recover the entire amount occurred.¿ there was no reported patient injury.The product was returned for analysis.A non-sterile powerflex extreme 5x4 80cm balloon catheter was returned from stock, received for analysis inside a plastic bag.The unit was returned already taken out from its original pouch/packaging box.Neither the inner pouch nor the outer packaging box of the unit was returned for evaluation.Functional testing was intended to be performed.The unit was pre-inspected, and a lab sample inflator-deflator was attached to the inflation lumen on the hub of the unit and positive pressure was applied.The unit failed the inflation test due to a leakage that was present on the shaft at the proximal seal area of the unit.Per microscopic analysis, the unit was sent to sem analysis to identify the possible root-cause of the leakage.Results showed that the shaft leakage was caused by a rupture on the body shaft surface.The inner surface presented no anomalies.However, the outer surface showed evidence of scratch marks near the rupture.This type of damage is commonly caused during the interaction of the shaft material with a sharp object or mechanical damage.It is very likely that the same factors that caused the observed scratch marks on the shaft outer surface mat have led to the ruptured condition found on the received device.It seems the shaft material near the rupture was torn due to the interaction of the shaft with a sharp object from the outside of the shaft.No other anomalies were observed during the sem analysis.Shipping of the unit and the way it was received for evaluation may have contributed to the observed condition.The damaged conditions may have occurred in transit since the devices were returned with the balloon covers removed from their original position and not in their sterile packaging.There was no lot number information provided due to the nature in which the devices were returned; therefore, a product history record (phr) review could not be generated.A ¿body/shaft leakage¿ was confirmed via device analysis for this returned unused device.A leakage was noted on the shaft at the proximal seal area of the unit, the outer surface showed evidence of scratch marks near the rupture.It is likely that the body shaft was damaged and interacted with something rough or sharp.However, shipping of the unit and the way it was received for evaluation may have contributed to the observed condition.The damaged conditions may have occurred in transit since the devices were returned with the balloon covers removed from their original position and not in their sterile packaging.Therefore, it is difficult to draw a clinical conclusion between the device and the results of the analyzed product.Without a lot number to conduct a phr review, and the manner in which the device was returned for analysis, it is not possible to determine if the reported failure could be related to the manufacturing process.Therefore, no corrective or preventive actions will be taken at this time.

When performing a shunt procedure, the balloon of three (3) 5mm x 4mm 80cm powerflex extreme percutaneous transluminal angioplasty (pta) balloon catheters were inflated; however, the balloons were blown, and the rated burst pressure (rbp) was not raised.¿as the balloon contracts in the state, the phenomenon of falling out continuously occurred, so a request from the hospital to recover the entire amount occurred.¿ there was no reported patient injury.The devices will be returned for evaluation, along with all other unused balloon catheters in stock.Addendum: during the product analysis of the unused balloon catheters returned, it was noted that a total of 4 additional devices had a shaft and/or balloon leakage.
