During use of a 6 x 4 and an 8 x4 powerflex p3 percutaneous transluminal angioplasty (pta) balloon catheter, there was leakage.There was no patient injury.Multiple attempts to obtain additional information were made without success.A non-sterile powerflex p3 f5 6 x 4 x 80 pta balloon catheter was returned (unit 2).The balloon was received deflated, no anomalies were observed.Functional analysis was performed, a lab sample syringe filled with water was attached to the luer hub of the catheter and successfully flushed.No resistance or loose material/matter was noted during flushing.An.035¿ guide wire sample was successfully introduced into the guide wire lumen via the tip all along the unit.No obstruction was noted.Finally, a three-way valve was attached to the inflation lumen port.Required pressure was applied for inflation, no anomalies were observed.No lot number was provided therefore a product history record (phr) review could not be generated.The reported ¿balloon leakage¿ was confirmed through analysis of the returned device noted as unit 1.The exact cause of the leakage could not be determined.However, the ¿balloon leakage¿ complaint was not confirmed for unit 2 as there were no anomalies noted.Device analysis of unit 1 revealed the balloon¿s inner surface had evidence of scratch marks and tears adjacent to the puncture marks and along the guidewire lumen on the proximal seal of the balloon.This type of damage is commonly caused when balloon material encounters a sharp object or mechanical damage.Although unknown, it is likely that handling of the device contributed to the event reported.Unit 2 performed as intended and inflated without difficulty during functional analysis.According to the instructions for use, which is not intended as a mitigation of risk, ¿if resistance is met during manipulation, determine the cause of the resistance before proceeding.Balloon pressure should not exceed the rated burst pressure.The rated burst pressure is based on the results of in vitro testing.At least 99.9% of the balloons (with a 95% confidence), will not burst at or below their rated burst pressure.Use of a pressure monitoring device is recommended to prevent over pressurization.Use only the recommended balloon inflation medium.Never use air or any gaseous medium to inflate the balloon.¿ neither the phr review nor the product analysis of unit 1 suggests that the event experienced by the customer could be related to the manufacturing process.Without a lot number to conduct a phr review for unit 2, 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.Pease note that this is related to the event reported in manufacturing report is 9616099-2019-03034.

During use of a 6x4 and a 9x4 (8x4) powerflex p3 percutaneous transluminal angioplasty (pta) balloon catheter, there was leakage.There was no patient injury.Two products were returned for analysis.Two non-sterile units of powerflex p3 f5 6x4 80cm pta balloon catheters were received for analysis coiled inside a plastic bag.Per visual analysis, no anomalies were noted.The balloon was received deflated.Per functional analysis a lab sample syringe filled with water was attached to the luer hub of the catheter and successfully flushed.Neither resistance nor loose material was noted during flushing procedure.Then, a.035¿ guide wire (lab sample) was successfully introduced into the guide wire lumen of the powerflex p3 balloon via tip all along through the unit.No obstruction was experienced during the insertion test.Finally, a three-way valve was attached to the inflation lumen port.Required pressure was applied to the device to inflate the balloon and no anomalies were noted.No lot number was provided therefore a product history record (phr) review could not be generated.The complaint reported by the customer as ¿balloon - leakage¿ was not confirmed since balloon was inflated successfully during functional test.Analysis results and phr review results do not suggest that the reported damages are related to the manufacturing process.Therefore, no actions will be taken.Please note that this is the first of two events reported by the same facility.The related manufacturing report is 9616099-2019-03034.
