Event Description
|
A distributor reported that a patient experienced burn, blisters, and erythema on their forehead and left cheek following a thermage cpt facial treatment.The clinic reported completing this treatment using adequate coupling fluid at power levels 1.0 - 4.5.The tip was inspected prior to use, as well as about every 80 pulses during use, with no observed abnormalities noted.Prior to treatment the patient was administered topical anesthetics and oral ibuprofen prior to undergoing treatment.At about 850 pulses the clinician noted small white blisters appearing on the forehead and reduced the treatment power level to 1.The treatment was then completed.Following treatment the clinician noted that there were blisters on the forehead and the left cheek was red and swollen.The patient was treated with hydropathic compress with ns+ dexamethasone, and growth factor gel.The following day it was reported the patient reaction on the forehead was recovered however the left cheek reaction remained aggravated with linear erythema and scabbing noted.Available pictures were reviewed.Scabs are visible on the patient left cheek along with redness.The current status reported as scabs with unknown outcome.

Manufacturer Narrative

The treatment tip was returned and the evaluation was completed.During evaluation of the treatment tip, service found a dielectric breakdown around the radio frequency trace.The investigation found that trace damage from the tip membrane are caused by stress concentrations on the flex assembly at the adhesive edge that damaged the radio frequency trace, causing arcing and subsequent burn-through of the flex circuit membrane.This burn through can cause risk to the patient during treatment.The tip passed the flow test, leak test, and thermistor test.The tip failed the visual inspection as dielectric breakdown was observed.No functional testing was performed due to the dielectric breakdown.A review of manufacturing records showed all requirements were met.The final test verification specifications are acceptable.No non-conformities or anomalies were found related to this complaint when reviewing the device history record.The root cause was determined to be a component issue.There is currently a corrective action in place for further investigation of the issue.
