Service was able to confirm the failure mode.Service confirmed damage to the tip membrane along the radiofrequency trace.Investigation found stress concentrations on the flex assembly at the adhesive edge that damaged the radiofrequency trace, causes 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 tip membrane.Thermage cpt system technical user¿s manual ((b)(4) ) instructs the operator to inspect the treatment tips for any signs of physical damage prior, during, and after treatment.With respect to all thermage systems clinicians should frequently inspect the tip membrane during treatment for signs of breakdown and build-up of foreign substances.With respect to the cpt system, solta recommends that a tip membrane inspection be performed at the outset of the procedure and every 50 (fifty) pulses thereafter.According to thermage cpt system technical user¿s manual ((b)(4)) burns are a known possible side effect of 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.A review of the manufacturing records showed all requirements were met.The lot history, trend analysis, risk analysis and/or directions for use review were considered acceptable, with the product performing within anticipated rates.Final test verification specifications are acceptable.No non-conformities or anomalies found related to this complaint when reviewing the device history record.No corrective action is required.
