Note: several follow up attempts have been made with the hospital but clinical innovations has not been able to get in contact with the initial reporter.Product evaluation: the complaint is not confirmed.No product evaluation could be performed because the device was not returned and no photos were provided by the customer.Investigation description: a dhr review could not be performed because the lot number is unknown risk assessment: per fmea risk-0029 rev.02, the complaint may be associated with the following potential failure mode: note: potential failure modes 1 - 6 share the same the same potential causes and are grouped together in the list below.Potential failure mode 7 is listed separately.Potential failure mode 1: user fails to follow recommendations of abandonment; 1) if no descent (progress) of the head occurs after 2 tractions.2) if delivery is not achieved or imminent after 4 tractions, or 3) if the vacuum cup detaches ("pops-off") twice.Potential effects: excessive attempts lead to fetal or maternal injury.Potential failure mode 2: user fails to locate the flexion point and locates the device on a different area potential effects: using the device on a different location other than flexion point cause inappropriate use of the device.Potential failure mode 3: user locates the flexion point but fails to note distance where finger meets introitus (fails to calculate the distance).Potential effects: user inserts the device on a different location causing inappropriate use of device.Potential failure mode 4: user fails to push cup posteriorly along maternal midline over flexion point.Potential effects: user inserts the device on a different location causing inappropriate use of device.Potential failure mode 5: user fails to establish appropriate level (450 - 600 mmhg) of vacuum.Potential effects: the device disengages/pops off the fetal head.Potential failure mode 6: user creates vacuum but fails to exclude any maternal tissue.Potential cause: failure to exclude any maternal tissue causes cup detachment/pop-off.Harm 1: hematoma.Severity: 4.Potential cause: lack of attention, not qualified personnel.Probability of occurrence: 1.Risk is considered "monitor".Harm 2: abrasion.Severity: 2.Potential cause: lack of attention, not qualified personnel.Probability of occurrence: 1.Risk is considered "acceptable".Harm 3: fracture.Severity: 3.Potential cause: lack of attention, not qualified personnel.Probability of occurrence: 1.Risk is considered "acceptable".Harm 4: laceration.Severity: 3.Potential cause: lack of attention, not qualified personnel.Probability of occurrence: 1.Risk is considered "acceptable".Harm 5: death.Severity: potential cause: lack of attention, not qualified personnel.Probability of occurrence: 1.Risk is considered "monitor".Potential failure mode 7: user fails to initiate traction along axis of pelvis.Potential effects: excessive force is used.Harm 1: hematoma.Severity: 4 potential cause: user moves handle up and down while pulling; user moves handle side to side while pulling; not qualified personnel.Probability of occurrence: 1.Risk is considered "monitor".Harm 2: abrasion.Severity: 2.Potential cause: user moves handle up and down while pulling; user moves handle side to side while pulling; not qualified personnel.Probability of occurrence: 1.Risk is considered "acceptable".Harm 3: fracture.Severity: 3.Potential cause: user moves handle up and down while pulling; user moves handle side to side while pulling; not qualified personnel.Probability of occurrence: 1.Risk is considered "acceptable".Harm 4: laceration.Severity: 3.Potential cause: user moves handle up and down while pulling; user moves handle side to side while pulling; not qualified personnel.Probability of occurrence: 1.Risk is considered "acceptable".Harm 5: death.Severity: potential cause: user moves handle up and down while pulling; user moves handle side to side while pulling; not qualified personnel.Probability of occurrence: 1.Risk is considered "monitor".Root cause analysis: a root cause cannot be determined because the device was not returned.
