With the device in place, patients reported that they were only slightly hungry prior to meals
and were “pleasantly satisfied” after eating.
Hunger went away after eating just small amounts of food.
Randomized Study Results
Cross Over
Mean BMI = 37
Consistent Weight Loss And
Metabolic Improvement
• All patients continue to lose weight until device is
removed. Higher pressure = steeper weight loss.
• 14 studies confirm same pattern of weight loss.
• Metabolic Considerations:
– Significant metabolic improvements similar to
RYGB and Sleeve. *
– Hypothesis: Device pressure in stomach causes
decreased bowel transit time and increased
incretin response.

Anti-Migration
Tethers
Antimigration Strategy
• Temporary: Endoscopic suture or clip.
• Long Term: Mucosal Capture and Tissue in growth.
– “Locked in” by 2-3 weeks.
Deployment Device
Deployment Over Scope
Clinical Considerations
• More direct and continuous than food based
scenario.
• Significant satiety at baseline and fullness with
eating and drinking.
• No non-responders in any study.
• Patients continue to lose weight until device is
removed (88% mean EBWL at 8.4 months).
• Long Term Implant requires adjustability.
• Metabolic improvements.
Benefits
•
•
•
•
•
•
No incisions.
Potential outpatient sedation only.
Service overweight and obese population.
Children and adolescents.
More cost effective.
Offer second chance to post bariatric patients who
have regained weight.
• Safer and less invasive thus more readily adopted by
population.
• Service patients with metabolic disease but not
obesity.
Bariatric Surgery Only
Impacting less than 1%
Of Eligible Patients
Full Sense Status
• Design Freeze for device – August 2014.
• CE Mark in progress.
– ISO Quality Achieved.
• Centers in Europe and Canada Identified.
– Begin training this fall.
– Those centers will be training centers.
• Expected CE Mark in 2015
