The device was not returned for analysis.A review of the lot history record and complaint history of the reported lot could not be conducted because the lot number was not provided.It should be noted that the emboshield nav6 embolic protection system electronic instructions for use states: the emboshield nav6 device can only be used with the barewire filter delivery wire.Use of the device with any guide wire other than the barewire filter delivery wire will lead to loss of the filtration element during the procedure or an inability to retrieve the filtration element.The investigation determined the reported difficulties of detachment of the filter appears to be related to the use error; however, the reported treatments appear to be related to the operational context of the procedure as a snare device was used to retrieve the filtration element from the anatomy.There is no indication of a product quality issue with respect to manufacture, design or labeling.

It was reported that the procedure was performed to treat a lesion in the superficial femoral artery.An emboshield nav6 embolic protection system (eps) was used with an unspecified wire rather than the provided barewire.During retrieval, the filter came off of the wire, so a snare was used to successfully retrieve the device.No portion of the device remains in the anatomy.There were no adverse patient sequelae and no clinically significant delay in the procedure.No additional information was provided.
