A stable regimen is defined as 90 days without the introduction of or change in medication; Agrees to refrain from any type of reconstructive surgery/procedures that would affect body weight (such as abdominal lipoplasty or liposuction, mammoplasty, removal of excess skin or cool sculpting) during the follow-up period after the placement of the LGV. Exclusion Criteria: Genetically-caused obesity, such as Prader-Willi syndrome; or any disease state know to affect weight status such as Cushing's syndrome, untreated sleep apnea, inadequately treated thyroid disease; History of chronic and/or ongoing clinically significant conditions or disorders of the gastrointestinal (GI) tract, i.e. Gastroparesis and Inflammatory Bowel Diseases such as Ulcerative Colitis and Crohn's disease; Any abnormal stenosis or obstruction of the GI tract; Significant acute and/or chronic active infection including H. pylori and urinary tract infection; History, or signs and/or symptoms of acid-peptic disease (APD) or gastric or duodenal ulcer; Diagnosis of portal hypertension, cirrhosis and esophageal varices; Presence of renal or liver disease defined as estimated Glomerular Filtration Rate (eGFR) < 45 ml/min/1.73 m2, ALT or AST > 2x upper limit normal (ULN) or total bilirubin >1.5x ULN; Previous stomach or bowel surgery; Previous bariatric procedure or device including, but not limited to, intragastric balloons within the past twelve months, sleeve gastrectomy, endoluminal suturing and restrictive bands; History of adhesive peritonitis; Presence of a hiatal hernia greater than 3 cm; History of bleeding disorders such as hemophilia; Unable to tolerate abstinence from blood thinners, such as warfarin, during the peri-operative period; Anemia defined as either: Hemoglobin (Hb) value for females of <11.0 g/dl, for males <12.0 g/dl; Abnormal blood cell indices deemed to be clinically significant; Diabetes requiring insulin at baseline (Type 1 or uncontrolled Type 2 defined as an HbA1c >12%) or a significant likelihood of requiring insulin treatment in the following 24 months; History or known allergies to silicone or similar materials; Participation in other investigational study protocols. If a subject has recently completed participation in another drug or device study, the subject must have exited that study at least 90 days prior to being enrolled in this study. If a subject screen failed prior to receiving study intervention the subject may participate in the study; Concomitant use of (or within 90 days of screening), or unwillingness to avoid any use of, weight loss medications, weight loss supplements, weight loss herbal preparations and/or participation in any non-study-related organized weight loss program (commercial or medical) at any time during the study; Undergoing chronic steroid or immunosuppressive therapy, defined as use of any oral and/or injectable steroid of any dose within 90 days of screening; Smoking cessation within two years of study entry; Major abdominal surgery (other than appendectomy, cholecystectomy); Significant traumatic injury to the abdomen within 90 days prior to enrollment; Subjects or immediate family members (e.g., biological parents, children, grandparents) with a known diagnosis or pre-existing symptoms of autoimmune connective tissue disease such as systemic lupus erythematosus or scleroderma; Current use of medications known to cause metabolic disturbances, such as the antipsychotic agents olanzapine, quetiapine, and type 2 diabetes medication thiazolidinedione (TZD); Chronic use of Non Steroid Anti-Inflammatory Drugs (NSAID) which is defined as daily use for greater than one month (daily low dose aspirin is acceptable); History or presence of malignancy such as cancer within the last five years with the exception of successfully treated non-melanoma skin cancer; Any condition that, in the opinion of the Investigator, would compromise the well-being of the subject or the study or prevent the subject from meeting or performing study requirements.

Arms and Interventions

| Intervention/Treatment |
| --- |
|Device: Laparoscopic Gastric Vest (LGV)|The Laparoscopic Gastric Vest (LGV), branded the ReShape Vest™, is a long-term, silastic, implantable system that is placed around the stomach to encompass the gastroesophageal junction to the Incisura Angularis. The main materials used to make the LGV is Implant Grade Silicone (95%) and Barium Sulfate (5%). The LGV is indicated for weight reduction for obese people with a Body Mass Index (BMI) between ≥35 kg/m2 and ≤55 kg/m2. It is indicated for use in adult patients (≥22 to ≤65 years) who have failed one or more conservative weight reduction alternative(s), such as supervised diet, exercise, and behavior modification program(s).|
