Primary Outcome Measures:
  • Reduction in serious device and procedure related adverse device effects. [ Time Frame: 6 months ]

Secondary Outcome Measures:
  • Improvement in espophageal pH [ Time Frame: 6 months ]

Enrollment: 143
Study Start Date: December 2002
Study Completion Date: June 2008
Primary Completion Date: June 2006 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Sham Comparator: Sham
This arm of the study has the procedure but does not get the Gatekeeper prostheses. The Sham arm has the option to cross-over to the Treatment arm at the 6-month visit.
Device: Gatekeeper Reflux Repair System
The Gatekeeper System™ consists of a specialized 16-mm overtube assembly, a 2.4-mm diameter prosthesis delivery system (1-mm diameter needle, dilator, and 2.4-mm diameter sheath), a pushrod assembly and Gatekeeper Prosthesis. Up to 4 prostheses will be implanted at the initial procedure and retreatment with up to four more prostheses will be allowed at 3-months if the subject has a GERD HRQL score >15.
Other Name: Gatekeeper
Active Comparator: Treatment
The treatment arm has the Gatekeeper devices implanted.
