RING MAGNET FOR OBESITY MANAGEMENT

摘要

A system and method for restricting an anatomical passageway includes a plurality of ring magnet pieces. Each of the plurality of ring magnet pieces has an inner and outer surface, and a pair of magnetic end sections between the outer surface and the inner surface, each end section having a characteristic magnetic field arrangement. An insert includes at least one of a magnet and a magnetic material. The ring magnet pieces are capable of forming, due to their magnetic field arrangements, an enclosed ring around an anatomical passageway. The insert is magnetically held in place by the ring magnet pieces when positioned in the anatomical passageway.
