It was reported that on (b)(6) 2021, a percutaneous intervention was performed on the left main (lm) coronary artery lesion.Lm balloon dilatation was performed by a trek rx dilatation catheter.Following, the balloon was unable to deflate and became stuck in the lm.The patient went into a critical condition.An emergency access site was created in the femoral artery and the inflated balloon was successfully removed via snare.During removal attempts, the device had separated in two places.Once outside the anatomy, the balloon was noted rigid and unable to deflate.Reportedly, there is suspected fault with the trek devices internal braiding, although this was not confirmed.No additional information was provided regarding this issue.

Visual inspection was performed on the returned device.The reported separation was confirmed.The reported failure to deflate could not be replicated in a testing environment due to the condition of the returned device.The reported entrapment of device could not be replicated in a testing environment as it was based on operational circumstances.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 of the reported lot did not indicate a lot specific quality issue.The reported patient effect of hypotension is listed in the coronary dilatation catheters (cdc), trek rx global, instructions for use (ifu) as a known patient effect.Factors that may contribute to failure to deflate the balloon include, but are not limited to, deflation technique, loose connection with the indeflator, contamination in the inflation lumen or damage to the guide wire and/or inflation lumen.The investigation was unable to determine a conclusive cause for the reported failure to deflate; however, the reported entrapment of device, separations, removal of foreign body and additional treatment appear to be related to circumstances of the procedure.A conclusive cause for the reported patient effects of hypotension and tachycardia and the relationship to the device, if any, cannot be determined.Based on the information reviewed, there is no indication of a product quality issue with respects to the design, manufacture, or labeling.
