Virtua Health has introduced a new, minimally invasive weight-loss procedure using magnetic technology, becoming the first health system in New Jersey and the Greater Philadelphia region to do so. The technique, called magnetic compression anastomosis, reduces the need for traditional surgical methods such as cuts, stitches, or staples during bariatric surgery.
The procedure uses the MagDI System developed by GT Metabolic. This system was approved by the U.S. Food and Drug Administration in 2024. It involves two small magnets that gently bring together parts of the intestine to form a connection that heals naturally without leaving foreign materials behind. After healing is complete, the body expels the magnets on its own. The resulting passageway limits calorie absorption.
“This is a major advancement in bariatric care,” said Samuel Wasser, MD, director of bariatric surgery at Virtua Health. “We are offering patients a safer, gentler option with excellent outcomes and faster recovery—and we are the 17th health system nationwide to provide this new treatment option.”
Known as magnetic duodeno-ileostomy surgery, this malabsorption procedure restricts how many calories a person absorbs from food and is typically performed alongside or after traditional restrictive surgery that reduces stomach size.
“Virtua Health continues to lead the region in adopting cutting-edge technologies that improve patient outcomes and enhance the surgical experience,” said Emeka Acholonu, MD, bariatric surgeon.
Currently, Drs. Wasser and Acholonu are the only surgeons providing this service in both New Jersey and Greater Philadelphia. Most health insurance plans cover this procedure.
