Primary Outcome Measures:
  • To Evaluate the Incidence of All Adverse Events at Various Time Points. [ Time Frame: 5 years ]
  • To Monitor the Improvement of GERD Symptoms. [ Time Frame: 5 years ]
    Percentage of participants with a 50% or more reduction in total GERD-HRQL score is indicative of a substantial improvement in GERD symptoms


Enrollment: 44
Study Start Date: February 2007
Study Completion Date: August 2013
Primary Completion Date: July 2009 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Implantable Device Device: Torax Medical, Inc. LINX Reflux Management System
Implantable device, Magnetic Esophageal Sphincter

Detailed Description:
The purpose of this feasibility study is to collect preliminary performance and safety information and develop procedural optimization for the Torax Medical Inc. Magnetic Esophageal Sphincter device (MES) in reinforcement of Esophageal Sphincter function to treat Gastroesophageal Reflux Disease (GERD). The information from this study will be used to support the design and conduct of an expanded clinical trial.
