It was reported that an unspecified 2.75x12mm trek balloon dilatation catheter (bdc) was prepped outside the anatomy prior to use, and the contrast mix was omnipaque 300x500.The bdc was inflated to 18 atmospheres; however, it failed to deflate after almost 10 minutes of trying.The balloon was intentionally ruptured using manual inflation with a syringe in order to remove it.There were no adverse patient sequela and no clinically significant delay in the procedure.No additional information was provided.

The device was not returned for evaluation.A review of the lot history record and complaint history could not be conducted because the lot number was not provided.The investigation was unable to determine a conclusive cause for the reported deflation issue; however, the additional treatment appears to be related to operational context.Factors that may contribute to difficulty deflating the balloon include, but are not limited to, deflation technique, contrast concentration, loose connection with the indeflator, contamination in the inflation lumen or damage to the guide wire and/or inflation lumen.There is no indication of a product quality issue with respect to design, manufacture or labeling of the device.E1 country updated from isr to pse.
