The angiosculpt device was returned for evaluation.Visual inspection found a kink on the intermediate shaft, proximal to the exit port.During functional testing, using a syringe filled with water, the guide wire lumen was flushed.Then, using an indeflator filled with water, vacuum was pulled to aspirate the air from the device.Next, through the exit port, a laboratory 0.014" guidewire was inserted without resistance.Using the same indeflator, the device was pressurized but unable to inflate due to a leak observed at the exit port.The overall catheter measured at 152.7 cm, which indicates the shaft was severely stretched, since the catheter working length specification is 139 +/-3 cm.Additionally, the shaft was necked and the inner member within the distal shaft was separated and damaged.This caused the pressure to flow from the inflation lumen, to the inner member, and leak out from the exit port.To confirm the balloon rupture, the device was dissected distal to the exit port, and a tuohy-borst adapter was attached and connected to the indeflator.The device was pressurized, but unable to inflate due to a leak observed at the distal tip that was likely caused by the separated inner member.Therefore, 0.0155 in.Mandrel was used to plug the distal tip to redirect pressure to the inflation lumen.The device was pressurized to 8 atm (nominal), and this time, the balloon was able to inflate and maintain pressure.Block h6: based on the device evaluation, there was no balloon rupture as reported by the customer.The probable root cause of the air embolism is likely due to user error.Per the complaint details, force was applied to remove the stylet which damaged the device but continued with the case, and the device was not flushed prior to use.The ifu includes the following: -examine carefully for damage and catheter integrity.Do not use if the catheter has bends, kinks, missing components or other damage.-flush the guide wire lumen with saline by carefully inserting the distal catheter tip into the distal end of a 10-cc syringe and injecting saline until droplets emerge from the proximal guide wire lumen.-embolism is listed as a possible adverse effect of the procedure.Submission of this report does not, in itself, represent a conclusion by the manufacturer and/or authorized representative or the national competent authority that the content of this report is complete or accurate, that the medical device(s) listed failed in any manner and/or that the medical device(s) caused or contributed to an alleged death or deterioration in the state of the health of any person.

The angiosculpt catheter was used in a coronary procedure.During prep, the stylet was difficult to remove, thus the physician pulled hard on the shaft to remove.Prior to use, the catheter was aspirated, but not flushed.During inflation at 8 atm, the balloon ruptured, and a small air embolism traveled into the distal coronary bed causing the patient to experience temporary angina.The angina was resolved with no additional intervention required.A new angiosculpt was used to complete the procedure and patient left the room without pain.During the device evaluation, there was no balloon rupture present.This adverse event is being submitted due to user error; resulting in embolism.
