Gerd Treatment Endoscopic Surgical System

Stretta TherapyThe trans-oral Stretta catheter system employs a proprietary application of RF energy that is low-power (5 Watts) and generates low temperatures (65°C to 85°C) during a series of 14 one-minute cycles. This process remodels the lower esophageal sphincter (LES) muscle and gastric cardia. The FDA initially approved Stretta for use in 2000 and issued an updated clearance for the RF1 generator in 2011. Clinical studies have shown that Stretta RF treatment leads to substantial reductions in tissue compliance and transient LES relaxations, as well as an increase in LES wall thickness as a result of muscle growth. These mechanisms reduce spontaneous regurgitation caused by transient relaxations of the sphincter and restore the natural barrier function of the LES, which are two of the primary causes of GERD. Stretta is generally administered as an outpatient procedure under conscious sedation.
