It was reported that the procedure was performed to treat a de novo lesion in the heavily calcified, heavily tortuous right coronary artery.After an unspecified stent was implanted, a 2.75x12mm nc trek balloon dilatation catheter (bdc) failed to cross due to the anatomy, and the proximal shaft separated.The separated portion was simply withdrawn without resistance, and a 2.5x8mm nc trek balloon was used to successfully complete the procedure.There were no adverse patient effects and no clinically significant delay in the procedure.No additional information was provided.

H6: device code 2017 incorrect prep.Visual inspection was performed on the returned device.The reported separation was confirmed.The reported failure to advance 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.It should be noted that the coronary dilatation catheters (cdc), nc trek rx, global, instruction for use (ifu) states: all air must be removed from the balloon and displaced with contrast prior to inserting into the body, (repeat steps 5a through 5g, if necessary); otherwise, complications may occur.In this case, it is unknown if the ifu violation caused or contributed to the reported complaints.The investigation determined the reported complaints appear to be related to operational context.There is no indication of a product quality issue with respect to design, manufacture or labeling of the device.Na.
