Correction h10: initial mdr was missing full product evaluation."the tip passed the flow test.The tip failed the leak test, the thermistor test, and visual inspection as a dent and dielectric breakdown was observed." the data log was evaluated and showed errors had occurred during treatment.An error indicates a recoverable problem that requires operator intervention.If the error occurs during a radio-frequency (rf) treatment, the rf 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 data the system and handpiece performed as expected.There were no e138 errors listed during this treatment.Breakdown of the dielectric material on the tip 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.Defects on the tip membrane can lead to a raise in temperature of the tip during treatment.Thermage cpt system technical user¿s manual 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.According to the thermage cpt system technical user¿s manual, redness, burns, and pigment changes are possible reactions to the treatment.Erythema / blanching may occur in mild form and typically resolves within a few hours.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 for the serial/lot number.The lot history, trend analysis, risk analysis and/or directions for use review were considered acceptable, with the product performing within anticipated rates.Based on the available information, damage to the tip caused this event.No corrective action required.
