The treatment tip and data card were returned for evaluation.The data log showed several force errors and thermistor errors occurred during the treatment including: error 128- overforce during rf on.Error 131-underforce during rf on.Error 171-thermistor 1 disconnected.Error 173-thermistor 3 disconnected.Error 211-force too high when button pushed.Error indicates a recoverable problem that requires operator intervention.If the error occurs during a radio-frequency treatment, the radio-frequency delivery will be stopped, then a post-cooling step will be completed prior to generating an ¿error tone¿ and displaying the event code and event message.After the error tone, the system will transition into ¿action required¿ mode and will display text with instructions for the operator indicating what action may be required to resolve the issue.Based on the evaluation of the data, the handpiece and system performed as expected.The treatment tip passed leak and flow testing and visual inspection.No dents, scratches, blemishes or dielectric breakdown was observed.Functional testing was performed (50 treatments) with no errors or other issues observed.A review of the manufacturing records showed all requirements were met.The lot history, trend analysis, risk analysis and directions for use review were considered acceptable, with the product performing within anticipated rates.Review of manufacturing records show final manufacturing test verification specifications are acceptable.No nonconformities or anomalies were found related to this event when reviewing the device history record.According to thermage cpt user manual, redness, burns, and hyperpigmentation are known possible reactions to treatment.The procedure may produce heating in the upper layers of the skin, causing burns and subsequent blister and scab formation.There is a small chance of scar formation.Application of topical steroidal or antibiotic preparations may be of benefit.In the rare instance of a burn that results in a scar, the scar will probably be very small and respond readily to removal with a laser device.Based off the available information, redness, burns, and hyperpigmentation are known possible reactions to treatment.No corrective action is necessary at this time.
