Merge healthcare conducted an internal quality investigation to address this issue that has been previously reported in recall (b)(4), fda recall number (b)(4).Merge healthcare received reports of the hemo monitor application unexpectedly stopping to display and update patient data.When this issue occurs, the hemodynamics system is no longer capturing patient data.For customers who experience this issue, it is recommended that the hemo monitor pc is power cycled.Once the system is powered up, the hemo application should restart with normal functionality and will once again display, update and record patient data.The restarting of the hemo monitor pc may result in a delay of up to two minutes while the system reboots.The investigation and troubleshooting activities conducted by merge healthcare found that the issue occurred due to an error when interfacing with a specific location within a schiller pdm (patient data module) file.Merge has validated and released a firmware fix for this issue.This fix is incorporated into the software upgrade of merge hemo 9.40.3 patch 1 (or later), or merge hemo 10.0.3 patch 1 (or later).The correction has been verified to be effective as is evidenced through the large reduction of customer complaints concerning this issue.This event occurred due to the customer remaining at hemo v9.40 after the recall notification was sent to the customer on 29mar2016.There have been no responses to that notification and subsequent follow ups.Tech support will contact the customer to schedule the needed upgrade to hemo v9.40.3 patch 1 which corrects the issue.Once the upgrade had occurred and confirmed functional, a supplemental report will be submitted.(b)(4).

Event Description
|
Merge hemodynamics displays, measures, and records physiological data from a human patient undergoing a cardiac catheterization procedure.The system comprises the patient data module and the merge hemodynamics hemo monitor pc.The two units are connected via a serial interface.All vital parameters and evaluations are registered and calculated in the patient data module.This data is then transmitted to the merge hemodynamics hemo monitor pc via the serial interface.All data can be shown and monitored on the merge hemodynamics hemo monitor pc.On (b)(6) 2019, a customer reported to merge healthcare that the hemo monitor was intermittently shutting down on its own and it had occurred a couple of times recently.Information obtained from the customer revealed that one occurrence was during a procedure.The hemo monitor was rebooted/power cycled and the issue was readily corrected.The other occurrence happened prior to a procedure starting.No date for the first event was provided, so the date captured of this report is the date the customer called in to report the issue.With merge hemo not presenting physiological data during treatment, there is a potential for delay in treatment that could result in harm to the patient.However, the customer confirmed that the issue was resolved after a reboot of the hemo monitor.Reference complaint (b)(4).
