Clinical Trials


The SEAM trial is an FDA approved research study using a Self-Forming Magnet Anastomosis Device for ileostomy reversals.

What Are Self-Forming Magnets (SFM) & How Do They Work?

The Self-Forming Magnet study device is a pair of eight-sided magnets that are made, in part, of a metal containing nickel-titanium. The Self-Forming Magnet study device is used to form the connection (also called an “anastomosis”) between two parts of the bowel to reverse the ileostomy.

Permanent Staples 

Unlike permanent staples or absorbable sutures, the magnets pass through the gastrointestinal tract after the anastomosis is formed and leave no permanent implant inside the patient.

GIW Surgical Devices 21-002 is limited by U.S. law to investigational use and is not approved for sale or distribution in the U.S.

*The self-forming Magnet Device is considered an investigational device by the United States Food and Drug Administration (FDA) as it has not been approved for sale by the FDA.
