Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
A one-time, surgical procedure involving percutaneous, single-port access placement of a saline-filled silicone implant placed adjacent to the stomach and attached to the anterior abdominal wall. The implant is indicated for long-term implantation; however, it can be removed by means of a laparoscopic surgical procedure. Magnetic Resonance Imaging (MRI) procedures required prior to treatment, prior to discharge following treatment procedure, and at nine months post-implantation.

Outcomes
Primary outcome [1] 5368 0
The primary end point of this study will be the six-month efficacy rate as measured by average percentage excess weight loss (%EWL) for patients treated with the Vibrynt Paragastric Implant System. %EWL is defined as weight loss divided by baseline excess weight: (baseline weight - post-surgery weight) / (baseline weight - ideal body weight).
Timepoint [1] 5368 0

Secondary outcome [1] 9021 0
Evaluation of the ability to successfully place the Paragastric Implant utilizing the Percutaneous Single Port Access technique.

Day 1 (procedure day)
Secondary outcome [2] 9022 0
Improvement in co-morbidities including: type 2 diabetes mellitus, hypertension, dyslipidemia, sleep apnea, coronary heart disease, osteoarthritis, and gall bladder disease. Co-morbidity improvements will be assessed by means of physical examination and clinical pathology.

Short Musculoskeletal Function Assessment
Timepoint [3] 9023 0
Baseline and six months following implantation
Secondary outcome [4] 9024 0
Safety will be assessed by the incidence of severe or serious adverse events reported either by the patient or observed by the investigator, relating to the procedure or to the device itself either peri-operatively or in the follow-up period.
Timepoint [4] 9024 0
All events reported that occur anytime from day of procedure through six months following implantation

Eligibility
Key inclusion criteria
Patients who would otherwise qualify for bariatric surgery based on BMI and co-morbidity criteria put forth by the National Health and Medical Research Council (NHMRC) and the U.S. National Institutes of Health (NIH), and have presented to the Bariatric Clinic for consideration of weight loss surgery. These patients must have a Body Mass Index (BMI)
> 40 kg/m2 and </= 50 kg/m2,
or >35 kg/m2 and < 40 kg/m2 with one or more significant medical conditions related to obesity (co-morbid conditions of type 2 diabetes, dyslipidemia, hypertension, obstructive sleep apnea, osteoarthritis, coronary heart disease, and gallbladder disease).
Minimum age
18 Years
Maximum age

Can healthy volunteers participate?
No
Key exclusion criteria
Subject exhibits psychological or emotional characteristics which, in the opinion of the investigator, makes the patient a poor candidate for Paragastric Implant surgery; history of drug and/or alcohol addiction; women of childbearing potential who are not practicing an effective method of birth control or who are pregnant or lactating, or planning to become pregnant within 3 years; previous upper abdominal sugery that would interfere with placement of the Paragastric Implant; non-ambulatory; acute or chronic infection (localized or systemic); history of cancer or life expectancy < 5 years; presence of any of the following medical conditions: inflammatory diseases of the GI tract, anomalies of the GI tract, upper GI bleeding conditions, esophageal or gastric disorders, severe cardiopulmonary disease, uncontrolled hypertension, portal hypertension, uncontrolled diabetes mellitus, cirrhosis of the liver, chronic pancreatitis, hiatal hernia, or immunocompromised.

Summary
Brief summary
The Percutaneous Single Port Access Paragastric Implant Placement Procedure is a novel approach to the treatment of morbid obesity. The saline-filled Paragastric Implant is placed in a minimally invasive fashion into the abdominal cavity in the space adjacent the stomach, thereby reducing the ability of the stomach to expand and reducing oral intake. The Paragastric Implant volume can be adjusted by the addition or removal of sterile saline through a subcutaneous port.

This trial is a single-arm, prospective, multi-center study designed to demonstrate the safety and effectiveness of the Vibrynt Paragastric Implant System in the treatment of morbid obesity. The primary end point of this study will be the six-month efficacy rate, as measured by the average percent excess weight loss for patients treated with the Vibrynt Paragastric Implant System. Patients will be followed for three years for long term safety and efficacy evaluations.
