Intervention Details:
  • 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).

    Other Name: ReShape Vest™

Primary Outcome Measures :
  1. %Excess Weight Loss [ Time Frame: 12 Months ]
    Demonstrate at least 30% excess weight loss (%EWL)

  2. Rate of Related Serious Adverse Events [ Time Frame: 12 Months ]
    Evaluate safety by device and procedure-related serious adverse events

Secondary Outcome Measures :
  1. Rate of Related Serious Adverse Events [ Time Frame: 24 months ]
    To evaluate the device and procedure-related serious adverse event rate

  2. %Excess Weight Loss (EWL) [ Time Frame: 24 Months ]
    To demonstrate the maintenance of at least 30% EWL

  3. Percentage of Subjects With >=40% Excess Weight Loss (EWL) [ Time Frame: 24 Months ]
    To demonstrate at least 40% EWL for at least 40% of subjects compared to baseline

  4. Percentage of Subjects With >=50% Excess Weight Loss (EWL) [ Time Frame: 24 Months ]
    To demonstrate at least 50% EWL for at least 35% of subjects compared to baseline

  • Able to comprehend, follow and give signed informed consent;
  • Reside within a reasonable distance from the Investigator's treating office and able and willing to travel to the Investigator's office to complete all routine follow-up visits;
  • Ability to comply with all study requirements for the duration of the study, as outlined in the protocol, willing to submit to significant lifestyle changes that include diet, eating and exercise habits for the duration of the clinical study;
  • Females of childbearing potential (FOCBP) must be willing to avoid pregnancy throughout the duration of the study, including follow-up, and must agree to the following:
