It was reported that during use of the device for a cardiopulmonary bypass procedure (cpb), the central control monitor (ccm) unexpectedly shut down.The user attempted a reboot and a message "computer needs service" was displayed on the monitor.The product was changed out after the procedure.The surgical procedure was completed successfully.There was no delay, no blood loss, nor adverse consequences to the patient.Per clinical review: during cpb, the ccm shut down.There were no error codes or indication of an issue prior to the shutdown.The pumps continued to work, as did other devices that allowed for manual control.Thus, cpb was able to be maintained.The user elected to re-boot the system-1 during cpb and this would temporarily stop all of the pumps.When the system was re-booted, the pumps would have been able to be re-started in about 10-15 seconds.When the ccm finally attempted to come on-line, the message "system computer needs service" was posted on the ccm and no ccm functions were able to be used.This results in the inability to select a perfusion screen, and none of the safety systems (air, pressure, and level) would have been able to be activated.This would allow manual operation of the pumps to complete the procedure, but no safety functions or connections would be active.The ccm was changed out after the procedure was completed.The case was completed successfully, without associated blood loss.Even though the system was re-booted with short loss of pumping capacity, the actual surgical procedure was not delayed.There was no harm observed.

Investigation results: this issue could not be duplicated at subsidiary facility, however during lab evaluation the issue was duplicated.The single board computer (sbc) printed circuit board assembly (pcba) was the cause of the problem.The ccm started the boot up process then stopped near completion and displayed "system computer needs service" error message.When the pci1 connector on the sbc pcba was agitated, the ccm shut down and rebooted.Replacing the sbc pcba with a known good sbc pcba resolved the issue.If additional information becomes available on this complaint that would alter the facts and/or conclusion, a supplemental report will be filed accordingly.
