Exclusion Criteria:

  1. Diagnosed with type 1 diabetes

  29. Known immunocompromised status, including but not limited to individuals who have undergone organ transplantation, chemotherapy, or radiotherapy within the past 12 months, who have clinically-significant leukopenia, who are positive for the human immunodeficiency virus (HIV) or whose immune status makes the participant a poor candidate for clinical trial participation in the opinion of the investigator.
  30. With any implanted electronic devices or duodenal metallic implants
  31. Not a candidate for upper GI endoscopy or general anesthesia.
  32. Active illicit substance abuse or alcoholism (> 2 drinks/day regularly).

    Additional exclusion criteria to be confirmed during the screening process:

  38. HbA1c < 7.5% or > 11% at baseline visit
  39. Any severe hypoglycemic event since the screening visit
  40. Glucose level <54 mg/dl (3.0 mmol/l) in more than 1% of time by CGM since the screening visit
  41. Uncontrolled hyperglycemia with a glucose level >270 mg/dl (>15 mmol/L) after an overnight fast or >360 mg/dl (>20 mmol/l) in a randomly performed measurement that is confirmed by a second measurement (not on the same day) since screening visit
  42. Mean of 3 separate blood pressure measurements >180 mmHg (systolic) or >100 mmHg (diastolic)
  43. Women of child-bearing potential with a positive urine pregnancy test at baseline visit
  44. Grade III or greater esophagitis on endoscopy
  45. Abnormalities of the GI tract preventing endoscopic access to the duodenum
  46. Anatomic abnormalities in the duodenum that would preclude the completion of the treatment procedure, including tortuous anatomy
  47. Endoscopic observation of upper gastrointestinal abnormality such as ulcers, polyps, varices, strictures, congenital or intestinal telangiectasia
  48. Any other anatomical or endoscopic abnormalities/characteristics that, in the opinion of the investigator, would preclude safe use of the investigational device or procedure.
