A review of the device history record, which includes verification of all steps in the manufacturing of the pump, verification of all final testing performed by/on the pump, verification of sterilization, and packaging for subject pump was performed.The review did not identify any non-conformances, issues or capas associated with pump function.Device was not returned for additional evaluation and investigation.As additional investigation was not performed on the device, a definitive root cause for the alleged issue could not be determined.If additional information becomes available, a supplemental mdr will be sent.Internal complaint number: (b)(4).

Reporter contacted technical solutions to report that a patient's pump was explanted due to the device malfunctioning.Additional information was provided, which confirmed that a dye study had been performed in which the physician was unable to aspirate from the pump.During the explant procedure, the expected volume of drug in the pump was 16.4ml and 25ml was able to be withdrawn from the pump.The patient's pump and catheter were replaced with medtronic devices.

Devices were returned for additional evaluation and investigation.Visual inspection of the pump did not find any exterior anomalies.Functional analysis of the pump confirmed the pump successfully primed and flowed within design specifications.The current battery level was read and found to be within specification.Engineering did a reading of the prior 30 days of battery measurements and found five instances of the battery being "low" and two instances of the battery being "marginal".As the pump was explanted on (b)(6) 2022 and not received for analysis until (b)(6) 2023, flowonix is unable to account for the conditions during this time frame.Pump storage and/or conditions during transit may be a factor in the results of the battery readings that were "low" and "marginal".Two sections of catheter were received with the pump.A 101 cm section of catheter was returned with a distal end and was found to be occluded.It was not patent with air or sterile water injection (swi), confirming the complaint of underinfusion and issue with aspirating during dye study.The second section of catheter was 7.6 cm long and was found to be patent with air and swi.The section of occluded catheter was likely the reason for the issue observed in the complaint.Please note that the intended selection for the investigation finding code was: blockage identified.The code was not able to be selected at this time.Internal complaint number: (b)(4).
