Event Description

During implantation, the catheter is defective: error message e002 (dongle memory failure) and then e001 (zero impossible) while the patient was immobile.With a 2nd monitor, the zero was accepted with multiple trials but it showed negative value in the head of the patient.The next catheter worked well.

Our experts performed a visual inspection and a functional check.The visual inspection did not show any defect.When connecting the catheter to the monitor, a value of -40mmhg is displayed.The zero of the catheter has been erased and a new zero procedure is carried out without difficulty.The catheter has been tested for 14 days the zero remains very stable.The offset of -40mmhg appears when a mechanical stress (in this case 40mmhg) is exerted on the sensor prior to installation.Following zero, the stress was released.Causing an offset of -40 mmhg.As a result, the issue is confirmed and the cause is related to the use of the device (mechanical stress on the catheter during the procedure).
