Manufacturer Narrative

Investigation: the customer returned a used optia set for investigation.The presence of blood was noted throughout the set.The set appeared to be assembled correctly with no kinks, occlusions, missing parts or misassemblies.The inlet and return saline line roller clamps were both open upon receipt of the set.The return and inlet lines were found to be heat sealed.The ac and saline lines were flow tested and fluid was able to flow through the kit.Clotting was noted in the inlet and upper pressure sensor, reservoir and return pump header tubing.The channel was found to be full of blood indicating that rinseback had not been performed.Some clotting was also noted in the channel.A review of the device history record (dhr) for this unit showed no irregularities during manufacturing that were relevant to this issue.Investigation is in process.A follow up report will be provided.

Event Description
|
The customer reported that after more than 3 hours of csp collection procedure, they had an alarm concerning the centrifuge.When they restarted, the return line was full of air.They did not complete the return to the patient and there was no reported injury or medical intervention.Patient information is not available at this time.This product is not available within the us, but this report is being filed due to an alleged failure that could occur on a similarly marketed device platform cleared for use by the fda.
