As reported, the balloon of a 3mm x 4cm 135cm powerflex pro percutaneous transluminal angioplasty (pta) balloon catheter was leaking when tested during preparation.Positive pressure was being applied to the balloon when the leakage occurred.As a result, a non-cordis device was used to continue the procedure.There was no reported injury to the patient.The device was stored, handled, and prepped per the instructions for use (ifu) and there were no difficulties removing any of the sterile packaging components.The balloon was prepped with a 1:1 contrast to saline ratio and the device maintained negative pressure during preparation.The device is not available for evaluation.The hospital reported it as an adverse event to the china nmpa directly.

After further review of additional information received the following sections have been updated accordingly: complaint conclusion: as reported, the balloon of a 3mm x 4cm 135cm powerflex pro percutaneous transluminal angioplasty (pta) balloon catheter was leaking when tested during preparation.Positive pressure was being applied to the balloon when the leakage occurred.As a result, a non-cordis device was used to continue the procedure.There was no reported injury to the patient.The device was stored, handled, and prepped per the instructions for use (ifu) and there were no difficulties removing any of the sterile packaging components.The balloon was prepped with a 1:1 contrast to saline ratio and the device maintained negative pressure during preparation.The hospital reported it as an adverse event to the china nmpa directly.The device was not returned for evaluation.A product history record (phr) review of lot 82246846 revealed no anomalies or non-conformances during the manufacturing and inspection processes that can be associated with the reported event.The reported ¿balloon leakage - during positive pressure¿ was not confirmed as the device was not returned for analysis.The exact cause could not be determined.It was reported in the event description that positive pressure was applied to the balloon during device preparation.This is not recommended according to the preparation steps in the ifu and is listed as such.Additionally, without the return of the device for analysis, it is difficult to draw a clinical conclusion between the device and the event reported.According to the instructions for use, which is not intended as a mitigation of risk, ¿attach a 3-way stopcock to the inflation port, which is marked ¿balloon¿.Attach a partially filled syringe with heparinized saline to the stopcock, open the stopcock to the balloon and induce negative pressure.Hold the syringe and proximal end of the catheter above the distal end of the catheter and hold the balloon vertically with the balloon tip pointing down.While maintaining negative pressure close the stopcock to the inflation port.Remove the syringe and purge the air.To ensure air contained in the balloon and inflation lumen is removed, apply negative pressure twice as instructed and repeat steps 2-4.Without twisting, slide the forming tube off the balloon.Prepare an angioplasty inflation system with a 50% solution of contrast medium in sterile saline or similar solution.Purge the air from the inflation device.Connect the inflation device to the 3-way stopcock that is connected to the catheter inflation port, open the stopcock to the catheter and slowly fill the inflation lumen and the balloon will slowly fill with diluted contrast medium.Caution: do not apply positive or negative pressure to the balloon at this time.¿ neither the phr review nor the product analysis suggests that the event experienced by the customer could be related to the manufacturing process.Therefore, no corrective or preventive action will be taken at this time.
