The thermage cpt tip was returned and evaluated.The tip passed the flow test, leak test, and thermistor test.Functional testing was performed (50 treatments) with no errors or other issues observed.The tip failed visual inspection, as dielectric breakdown was observed.Investigation found that radiofrequency trace damage on the tip membrane is caused by stress concentrations on the flex assembly at the adhesive edge that damaged the radiofrequency trace, causing arcing and subsequent burn-through of the flex circuit membrane.Burnt radiofrequency trace on the tip membrane most likely caused the reported issue during treatment.All treatment tips are visually inspected for defects during manufacturing and packaging.A review of the manufacturing records showed all requirements were met.Final test verification specifications are acceptable.No non-conformities or anomalies found related to this complaint when reviewing the device history record.There is an existing nc/capa opened for this type of complaint.
