Correction: e5 facility name - from: (b)(6), to: (b)(6).The treatment tip was returned and the evaluation was completed.During evaluation of the treatment tip, service found a tear on the tip membrane.The tip passed the flow test and thermistor test, but failed the leak test and visual inspection for dents on the tip surface.Functional testing was not performed due to the damage on the tip surface.The thermage user manual instructs the operator to inspect the treatment tips for any signs of physical damage prior to, 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, burns and blisters 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.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.
