The shaft of a saber balloon catheter had a leak.There was no reported patient injury.The procedure was completed with another saber pta balloon catheter.There was no difficulty removing the product from the hoop or protective balloon cover.The device was prepped per the instructions for use.There was unusual force used during the procedure.Contrast leaked out of the catheter.The balloon was still able to be inflated, despite the leak in the catheter.There are no procedural films or cd¿s available for review.Additional procedural details were requested but are unknown.The product was returned for analysis.A non-sterile saber 7mm x 6cm 90 balloon catheter was returned.Per visual analysis the balloon catheter was coiled inside of a clear plastic bag.The product was unpacked and received without the balloon being inflated.No damages or anomalies were observed on the balloon or the rest of the device.The guide wire lumen was flushed and a lab sample guide wire was inserted through it.A stopcock (three-way valve) was attached to the inflation lumen port in order to apply negative pressure and purge the balloon of air.The inflator/deflator device was attached to the inflation lumen.The device nominal pressure is 6atm (six atmospheres).The balloon inflation test was done applying pressure with the inflator/deflator device until the manometer reached the nominal pressure of 6atm, the balloon inflated as expected and no leakage on the catheter was detected.Balloon inflation pressure remained steady.A product history record (phr) review of lot 17539125 revealed no anomalies or non-conformances during the manufacturing and inspection processes that can be associated with the reported event.The reported ¿body/shaft - leakage¿ was not confirmed by analysis of the returned device as functional analysis was performed successfully.Upon testing, the balloon inflated as expected and no leakage was detected on the catheter body.The exact cause of the reported event could not be determined.The device performed as intended and therefore the reported event could not be related to the manufacturing process; therefore, no corrective/preventive action will be taken at this time at this time.According to the safety information in the instructions for use ¿proper functioning of the catheter depends on its integrity.Care should be used when handling the catheter.Damage may result from kinking, stretching, or forceful wiping of the catheter.Forceful handling can result in catheter separation and the subsequent need to use a snare or other medical interventional techniques to retrieve the pieces.Always verify integrity of the catheter after removal.¿ according to the warnings in the safety information in the instructions for use ¿prior to angioplasty, the catheter should be examined to verify functionality and integrity, and ensure that its size and shape are suitable for the specific procedure for which it is to be used.Do not use if product damage is suspected or evident.Deflate the balloon by pulling vacuum on the inflation syringe or inflation device.Apply negative pressures to the balloon for about 30 - 85 seconds until the balloon is deflated.Remove the vacuum (do not apply pressure) and carefully withdraw and remove the catheter.Note: gentle counterclockwise rotation of the balloon may ease withdrawal from the sheath or from the percutaneous entry site.If the balloon cannot be withdrawn through the sheath, withdraw the catheter and sheath as a unit.¿ 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/preventive action will be taken at this time.
