It was reported that during a vein shunt intervention, during use of a non-abbott balloon dilatation catheter to 22 atmospheres (atm) for the third time, the tube of the indeflator tore.There was no adverse patient effect or a clinically significant delay in the procedure.A new 20/30 indeflator was used to successfully complete the procedure.No additional information was provided.

The device was returned for analysis.The reported material split, cut or torn was able to be confirmed.A review of the lot history record identified no manufacturing nonconformities issued to the reported lot that would have contributed to this event.Additionally, a review of the complaint history identified no other incidents from this lot.As there was no damage noted to the device during the inspection prior to use, it is possible that inadvertent mishandling during use resulted in compromising the hose assembly such that during the third inflation to 22 atmospheres resulted in the reported/noted material split, cut or torn indeflator-hose assembly; however this cannot be confirmed.The investigation determined a conclusive cause for the reported/noted difficulties cannot be determined.There is no indication of a product quality issue with respect to manufacture, design or labeling.Na.
