What is the MagDI™ procedure?

MagDI (Magnetic Duodeno-Ileostomy) is an FDA-cleared, minimally invasive procedure that uses two small magnetic devices to create a natural connection between sections of the small intestine. This connection helps improve metabolism and insulin sensitivity through hormonal changes similar to gastric bypass, without cutting or stapling the intestine.

How much weight can I expect to lose?

Patients who underwent sleeve gastrectomy plus MagDI achieved approximately 70–75% excess body weight loss (EBWL) at 12 months post-procedure.For patients without a sleeve, early data show modest but meaningful results. The main goal of MagDI™ is metabolic improvement, with weight loss as a secondary benefit.

Can MagDI™ help with diabetes?

Yes, early studies show that MagDI can improve blood sugar control by increasing the release of GLP-1 and other gut hormones involved in insulin production. This makes it a potential alternative or complement to diabetes medications, though larger studies are still underway to confirm long-term outcomes.

How much does the MagDI™ cost?

Eviva is developing a comprehensive self-pay package for the MagDI™ procedure designed to deliver exceptional value and transparent pricing.When paired with a self-pay Sleeve Gastrectomy, patients will benefit from significant savings compared to scheduling each procedure separately.Final pricing and package details will be announced soon. Please check back or contact our team for updates.

Does insurance cover the MagDI™?

Because MagDI™ is a newly FDA-cleared technology, most insurance carriers do not yet have established coverage policies for it. However, the creation of an intestinal anastomosis (the medical act of connecting two portions of the small intestine) is an existing, billable surgical procedure, and surgeons may use standard CPT codes for duodeno-ileostomy or small-bowel anastomosis when submitting claims.At this time, there is no dedicated CPT code for “magnetic duodeno-ileostomy” or “MagDI™.” Reimbursement will depend on the payer, indication, and documentation of medical necessity.Eviva will assist patients with insurance pre-authorization and cost estimates, and self-pay packages will also be available for those choosing to move forward outside of insurance coverage.

Is the MagDI™ surgery permanent?

Yes, it is a permanent procedure that forms a natural, permanent anastomosis.Although permanent, it can be safely undone laparoscopically by separating the connection, restoring your natural anatomy.

Is the MagDI™ procedure safe?

Clinical studies report 100% technical success in creating the connection and no leaks or bleeding at the anastomosis site. The magnets naturally pass through the body once healing is complete, leaving no permanent materials behind.

Will I have magnets inside me forever?

No. The magnets are naturally expelled through the digestive tract within a few weeks after surgery. What remains is a durable connection made entirely from your body’s own tissue.

How is the MagDI™ different from gastric bypass or gastric sleeve surgery?

Unlike gastric bypass, MagDI does not remove or reroute major portions of the intestine and does not leave foreign materials behind. Compared to sleeve surgery, it targets hormonal and metabolic pathways more directly, which can improve diabetes control without increasing surgical risk.

When will MagDI™ be available at Eviva?

Eviva is among the first centers in the U.S. preparing to offer MagDI™ following its FDA clearance in 2024. Availability will begin late 2025 and early 2026 as part of our early clinical rollout.

What is the MagDI™

MagDI™ is a magnetic system that creates a natural, suture-free connection between two parts of the small intestine.

It can be performed:

In combination with a Sleeve Gastrectomy, during the same operation or as a revision to an existing sleeve
Standalone, in patients with normal stomach anatomy

Benefits for type 2 diabetes (T2DM) and blood sugar management

Less food through the duodenum, more contact with the distal ileum → boosts incretin hormones (like GLP-1/PYY) that reduce appetite, slow gastric emptying, and enhance insulin response. These are the same hormonal pathways leveraged by Roux-en-Y gastric bypass and GLP-1 medications, but achieved with a minimally invasive, reversible connection created by magnets. Also, because vitamins and minerals go through the duodenum risk of malnutrition is very low. Early MagDI studies were designed with T2D resolution as a key endpoint, reflecting this mechanism.
