You may not qualify if…

• Diagnosed with type 1 diabetes
• History of diabetic ketoacidosis or hyperosmolar nonketotic coma

• Previous use of any types of insulin for >1 month (at any time, except for treatment of gestational diabetes) in last 2 years.
• Current use of insulin
• Hypoglycemia unawareness
• History of ≥1 severe hypoglycemia episode (defined by needing for third-party assistance) in past 6 months from the screening visit
• Known autoimmune disease, as evidenced by a positive anti-glutamic acid decarboxylase (GAD) test, including but not limited to celiac disease, or pre-existing symptoms of systemic lupus erythematosus, scleroderma or other autoimmune connective tissue disorder. (Participants with adequately controlled primary hypothyroidism may be included).
• Previous GI surgery that has changed GI anatomy or could limit treatment of the duodenum, such as Billroth 2, Roux-en-Y gastric bypass, gastric band or other similar procedures or conditions.
• Known history of a structural or functional disorder of the upper GI tract that may impede passage of the device through the upper GI tract or increase risk of tissue damage during an endoscopic procedure, including esophagitis, stricture/stenosis, varices, diverticula, or other disorder of the esophagus, stomach and duodenum.
• Active H. pylori infection (Participants with active H. pylori may continue with the screening process if they are treated with an appropriate antibiotic regimen)
• History of, or gastrointestinal symptoms suggestive of gastroparesis.
• Acute gastrointestinal illness in the previous 7 days

• Alcoholic liver disease, as indicated by ANI > 0
• Current use of anticoagulation therapy (such as warfarin) that cannot be discontinued for 7 days before and 14 days after the procedure.
• Current use of P2Y12 inhibitors (clopidogrel, prasugrel, ticagrelor) that cannot be discontinued for 14 days before and 14 days after the procedure.
• Unable to discontinue non-steroidal anti-inflammatory drugs (NSAIDs) during treatment through 4 weeks following the procedure. Use of acetaminophen and low dose aspirin is allowed.
• Use of systemic glucocorticoids (excluding topical or ophthalmic application or inhaled forms) for more than 10 consecutive days within 12 weeks prior to the baseline visit.
• Use of drugs known to affect GI motility (e.g. Metoclopramide)
• Use of weight loss medications such as Meridia, Xenical, Phentermine or over-the-counter weight loss medications (prescription medication)
