Manufacturer Narrative

A medical review of this case determined this event was not a serious injury.Based on the evaluation of the data, the handpiece and system performed as expected.Evaluation of the treatment tip confirmed damage along the rf trace of the tip.Investigation found damage to the rf trace are caused by stress concentrations on the flex assembly at the adhesive edge that damage the rf trace, causing arcing and subsequent burn-through of the flex circuit membrane.Based on the available information, this event was most likely caused by damage on the treatment tip.It was reported no permanent damage or scarring would occur because of this event.Errors seemed to have occurred due to improper hand technique.A review of the manufacturing records showed all requirements were met.Defects on the tip membrane can cause the radiofrequency energy, delivered by the system, to focus in a small area of the membrane, rather than to be uniformly distributed over the entire membrane area and can potentially cause patient burns.This can also cause sparking from the tip during treatment confirming customers report of sparking during treatment.Final test verification specifications are acceptable.No non-conformities or anomalies found related to this complaint when reviewing the device history record for serial/lot number (b)(6).
