H6: device code 2017: above rbp.Visual inspection was performed on the returned device.The reported balloon rupture was confirmed.A review of the lot history record revealed no manufacturing nonconformities that would have contributed to this complaint.Additionally, a review of the complaint history identified no other similar incidents and/or complaints from this lot.The investigation determined the reported balloon rupture appears to be related to user error.It was reported by the account that the bdc was overinflated to 20 atmospheres (atms) when the balloon ruptured.It should be noted that the coronary dilatation catheters (cdc), trek rx and mini trek rx, global, instruction for use states: balloon pressure should not exceed the rated burst pressure (rbp).The rbp for the trek rx device is 14 atm; therefore, rbp was exceeded.In this case, it is likely the ifu deviation resulted in the reported balloon rupture.Additionally, it was reported that the procedure was to treat a calcified renal artery.It should be noted the coronary dilatation catheters (cdc), trek rx and mini trek rx, global, ifu states: the trek rx coronary dilatation catheters are indicated for: balloon dilatation of the stenotic portion of a coronary artery or bypass graft stenosis, for the purpose of improving myocardial perfusion, balloon dilatation of a coronary artery occlusion, for the purpose of restoring coronary flow in patients with st-segment elevation myocardial infarction, balloon dilatation of a stent after implantation.In this case, it is unknown if the reported ifu violation caused or contributed to the reported complaint.There is no indication of a product quality issue with respects to the design, manufacture, or labeling of the device.H6: device code 2017: above rbp was added.
