  20. Beck Depression Inventory (Short) Score ≥ 12 and/or uncontrolled depression after pre-enrollment psychological and medical assessment.
  21. Patient score >2 in any of the 9 identified symptoms on the Gastroparesis Cardinal Symptom Index (GCSI)
  22. Patient with a 13C-Spirulina Gastric Emptying Breath Test (GEBT) result that is less than a kPCD/min of 34.4 at 120 minutes or 43 at 180 minutes
  23. Non-ambulatory or has significant impairment of mobility (i.e. cannot ambulate for 30 minutes).
  24. Known hormonal or genetic cause for obesity including untreated hypothyroidism (TSH >5.0 U/ml).
  25. Participating in another clinical study.
  26. Subjects with a personal history of allergic/anaphylactic reactions including hypersensitivity to the drugs or materials that will be utilized in the study procedure.
  27. Physician's assessment that the subject is not an appropriate candidate. If significant findings for depression and/or suicidal ideation are identified, the psychologist(s) assigned to the study will be contacted and arrangement will be made for immediate intervention according to the Institution's standard procedure.

Brief Summary
This study has been expanded to a four center, open-label, 2-group randomized pilot study evaluating a treatment for obesity.
Detailed Description
This study has been expanded to a four center, open-label, 2-group randomized pilot study evaluating a treatment for obesity. The intent is to evaluate the safety and preliminary efficacy of a new Snowshoe suture placement pattern, Pose 2 (sutures placed in the mid + distal body without fundus), with a moderate intensity diet and exercise program, as compared to diet and exercise alone. The procedure will be performed using the g-Cath EZ Delivery Catheter with Snowshoe Suture Anchors (AKA g-Cath or g-Cath EZ) and associated devices (g-Prox EZ, g-Lix and Transport), known collectively as the Incisionless Operating Platform (IOP). Efficacy will be evaluated based on changes in weight loss for all subjects through 12 months. Adverse events will be recorded throughout the duration of the study.
