Service reviewed the data logs and based on the evaluation of data, the system and the handpiece performed as expected; but not the treatment tip.The customer used two treatment tips for this treatment.The system started to intermittently loose connection to the tm1 in about half of the treatment.Once they switched to different tip, the problem was resolved.Service looked further into the calculated impedance data related to output current and power and everything appeared correctly.Evaluation of the treatment tip confirmed damage along the radiofrequency trace of the tip.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.Investigation found damage to the radiofrequency trace are caused by stress concentrations on the flex assembly at the adhesive edge that damage the radiofrequency 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.Both the thermage user manual (p009240-06 rev.A) and technical bulletin tb-19 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 (p009240-06 rev.A) burns, blisters, scabbing, are known possible patient reaction to thermage 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.A medical review of this case determined this event was not a serious injury.The lot history, trend analysis, risk analysis and/or directions for use review were considered acceptable, with the product performing within anticipated rates.No corrective action required.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).No capa is required, since there is no non-conformance.
