The Stretta RF generator is a pole-mounted 4‑channel RF generator to deliver RF energy to treat gastroesophageal reflux disease (GERD). During the procedure, known as Stretta Therapy, RF energy is delivered to treatment sites above and below the gastroesophageal junction. Stretta Therapy is non‑ablative because it does not remove or destroy tissue but regenerates the target tissue by creating hypertrophy that thickens the musculature to improve GERD symptoms. The generator has an integrated irrigation pump to cool the mucosal tissue during therapy and a color display to guide the user through equipment setup and the treatment procedure. The operator controls energy delivery through a footswitch.
