It was reported that the procedure was performed to treat a lesion with mild calcification in the left anterior descending artery.A 3.0 x 15mm nc trek balloon dilatation catheter (bdc) was advanced without any resistance and the balloon crossed the target lesion.However, the balloon failed to inflate during the first inflation.The unspecified indeflator was changed, thinking the indeflator was the cause but the balloon would still not inflate.Therefore, the bdc was retracted to be removed.Although there was no resistance, the mid shaft became separated during removal.The separated portion was withdrawn with the guide wire as a single unit.The patient was stable and the procedure was continued with an unspecified balloon.There were no adverse patient effects and no clinically significant delay in the procedure.No additional information was provided.

Visual and functional inspections were performed on the returned device.The reported separation was confirmed.The reported inflation issue could not 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 similar incidents and/or complaints from this lot.The investigation was unable to determine a conclusive cause for the reported inflation issue; however, the reported separation appears to be related to operational context.There is no indication of a product quality issue with respects to the design, manufacture, or labeling of the device.
