Event Description
|
Medtronic received information that at first start-up of this 560 bio-console, the user noticed that error codes were present.The console was shut down and restarted, and afterward there were no errors present.The user then started the prime procedure, and for ~10 to 15 minutes, with the unit running at a very low speed, no issues were observed.When the user attempted to raise the speed by a small amount (set point was lower than 2000 revolutions per minute) the external motor speed rose to the maximum level.It was not possible to reduce the speed, so the customer replaced the bio-console 560 with a bio-console 550 and was then able to perform the procedure.It was reported that use of the external drive motor continued; it was only the bio-console that was replaced.There were no adverse patient effects as a result of the event.

Onsite instrument inspection by (b)(4) technical service (ts) was unable to reproduce the reported motor speed issue.The unit was then taken to the medtronic ts engineer's workshop for additional testing and service.As a preventative measure, the technical service representative replaced the system controller circuit board, flow/pressure circuit board, internal user interface cable, and external motor.A software upgrade was also performed.The error and the event log file for the instrument was provided to the (b)(4) for additional analysis and investigation.Upon completion of the investigation, a supplemental report will be filed.(b)(4).

Manufacturer Narrative

Review of the 560 bio-console data log confirmed the occurrence of the reported event; however, the technical service engineer was unable to duplicate the reported issue during testing of the instrument.Based upon the information provided, the investigation concluded the event appeared to have been caused by an intermittent function of the hall effect sensor or related parts.However, since the issue could not be duplicated, the root cause could not be confirmed.As such, all related components were replaced by the technical service engineer to resolve the issue.The instrument was tested after the replacements were made and performed according to specifications.Clarification: in the previous report filed for this event, one of the circuit boards that were replaced as a precautionary measure was described as the flow/pressure printed circuit board.Additional information has been received from the field service technician clarifying that it was the motion/pressure printed circuit board that was changed.(b)(4).
