Final device investigation found that the device was returned with a portion of the outer coating torn/worn/scratched away exposing the wire braiding and creating rough surfaces.The device was coiled and had several kinks in the length of the shaft.Upon evaluation, the device did not pass the straightness (centerline) test, which was possibly due to the manner in which the device was returned.The mobility of the device was also affected; the device did not fully deflect as intended.The device was electrically tested and failed the acoustic verification/calibration test, but passed all other electrical testing including hi-pot, signal strength and ultrasound testing.The damage to the outer coating of the shaft was possibly due to the device being packaged for return without being adequately secured causing excess friction during return shipping.The device history record was reviewed, and no discrepancies were noted.
