Manufacturer Narrative

Investigation summary: with all the available information, boston scientific concludes that the reported specific message error could not be replicated; therefore, the event cannot be confirmed.However, analysis did identify error code 219 (faulty delivery device on generator) upon priming.The delivery device backplate was opened and found the coil burnt.Based on information available it is probable that the burn coil likely contributed to the identified error code during priming.The cause of the reported event that led to aborting the procedure, could be traced back to the burnt coil component.Device history record (dhr): the device history record (dhr) confirmed that the device met all material, assembly and performance specifications.Device technical analysis: the product was returned for analysis to our post market quality assurance laboratory.Visual analysis revealed the delivery device handle was in overall good physical condition.The external tubing had no kinks.The resonant frequency (rf) connecting cable was in good physical condition.The pins in the connector were clean and straight.The delivery device buttons were pressed and spring back 5 times without.During functional testing, the retract/deploy functionality and the feel of the buttons were tested; however, starting prime error code 219 (faulty delivery device on generator) occurred.The backplate and top housing of the delivery device were removed for internal visual inspection; device internal appeared normal except for the coil which appeared burnt.The delivery device could not complete priming and pretreatment sequence due to the observed damage to the coil.Labeling review: a review of the device instructions for use (ifu) was completed and did not reveal any evidence of device misuse, off-label use, or that the guidance in the ifu was not followed.Investigation conclusion: based on the analysis results and information available, the reported event is confirmed.A conclusion code of cause traced to component failure was assigned to this investigation.
