magnetic jejuno-ileal diversion study ("mji study")

Conditions: Obesity; Type 2 Diabetes

Summary: the purpose of this clinical research study is to evaluate the feasibility/performance, safety and initial efficacy of the gt metabolic solutions di biofragmentable magnetic anastomosis system (magnet system, di biofragmentable and hereafter referred to as the di magnet system) for creation of a side-to-side jejuno-ileal anastomosis in adults with obesity and type 2 diabetes mellitus (t2dm).

the purpose of this clinical research study is to evaluate the feasibility/performance, safety and initial efficacy of the gt metabolic solutions di biofragmentable magnetic anastomosis system (magnet system, di biofragmentable and hereafter referred to as the di magnet system) for creation of a side-to-side jejuno-ileal anastomosis in adults with obesity and type 2 diabetes mellitus (t2dm). this partial diversion of intestinal contents from jejunum to the ileum is intended to facilitate weight management/loss and improve metabolic outcomes. side-by side anastomoses are currently created by sutures, staples, and anastomotic compression devices. this study explores a partial jejuno-ileal diversion procedure creating a side-to-side anastomosis with magnetic compression anastomosis.
