Visual, dimensional, and functional analysis was performed on the returned device.The reported balloon rupture was unable to be confirmed; however, the guide wire exit notch was torn and leaked which is likely what the account perceived as the reported balloon rupture.The reported difficulty advancing the device could not be replicated in a testing environment as it was based on operational circumstances.Production record and corrective and preventive actions (capa) reviews were performed and revealed no indication of a product quality issue.Additionally, a review of the complaint history identified no other similar complaints from this lot.It was reported that the device was used to treat a lesion in the arterial pulmonary artery.It should be noted that the coronary dilatation catheters (cdc), trek rx and mini trek rx, global, instructions for use 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 ifu violation caused or contributed to the reported complaints.The investigation determined that the reported complaints appear to be related to operational context.It was reported that the bdc interacted with the patient¿s anatomy resulting in the reported difficulty advancing the device there was no damage noted to the balloon catheter prior to use or leak noted during preparation, which suggests a product quality issue did not contribute to the reported difficulties.Return device analysis noted a tear and a leak at the guide wire exit notch.The tearing of the guide wire exit notch appears to have resulted from an interaction with the guide wire.This type of mechanical damage can occur if an attempt is made to pull the catheter in an opposite direction as the guide wire.In this case, it is likely that the devices were manipulated during use resulting in the noted tear and subsequently noted leak, which gave the impression of a balloon rupture.Based on the reported information, there is no indication of a product quality issue with respect to the design, manufacture, or labeling of the device.H6: medical device problem code 1494 clarifier- incorrect anatomy.
