Group/Cohort Intervention/treatment
Gastric Bypass
Morbidly obese individuals who meet the criteria for and have chosen to undergo Gastric Bypass surgery.
Procedure: Gastric Bypass
Gastric Bypass surgery reduces the size of the stomach by use of staples. The smaller gastric pouch is then connected to the intestine bypassing a portion of the small intestine.

AspireAssist Aspiration Therapy
Morbidly obese individuals who meet the criteria for and have chosen to participate in Aspiration Therapy using the AspireAssist.
Device: AspireAssist Aspiration Therapy
AspireAssist employs an endoscopically placed A-Tube (similar to a gastrostomy tube) and a Companion system which facilitates portion control by aspiration of stomach contents 20 minutes after each meal combined with behavioral Therapy.

Primary Outcome Measures :
  1. Weight Loss [ Time Frame: year 1 - quarterly, years 2-5 once per year ]
    % Excess Weight loss based on ideal body weight with BMI of 25

Secondary Outcome Measures :
  1. Quality of Life [ Time Frame: annually, up to 5 years ]
    Quality of Life survey according to EQ-5D EuroQol survey

Other Outcome Measures:
  1. Complications [ Time Frame: within 30 days of procedure, after 30 days ]
    any surgical or post surgical complications, therapy related illness or adverse events
