Event Description
|
It was reported during the device preparation, the pressurewire x, wireless device when connected into the quantien system, the pd displayed a negative number and could not be modulated to zero.This was attempted several times, but the device still could not be modulated to zero.Additionally, the proximal tube materil possibly tore during preparation.There was no patient involvement and no reported clianically significant delay in the procedure.The device return analysis revealed the proximal tube material was torn 6.7cm proximal to the sensor.No additional information was provided.No additional information was provided.

Manufacturer Narrative

Visual and functional analysis was performed on the returned device.The reported signal calibration failure was not confirmed as the pressurewire was able to be functionally tested in a coronary artery simulator.The reported torn material was confirmed.The results of the functional testing were within the specifications for the pressurewire.A review of the lot history record identified no manufacturing nonconformities issued to the reported lot that would have contributed to this event.Additionally, a review of the complaint history identified no indication of a lot specific product quality issue.The investigation was unable to determine a cause for the reported communication or transmission problem (signal calibration failure).It may be possible that an insufficient electrical contact between the guidewire and pwx transmitter occurred; however, this could not be confirmed.Based on the reported information, the torn material located at the kink occurred during preparation.This damage likely occurred due to inadvertent mishandling and does not appear to have contributed to the reported signal calibration failure based on the results of the functional testing.There is no indication of a product quality issue with respect to the design, manufacture, or labeling of the device.
