摘要：
An implantable restriction device includes a plurality of beads and a plurality of links that join the beads together. The beads include a housing including a contact surface, a passageway extending through the hosing along an axis, and at least one magnet disposed around the passageway. Portions of the links are slidably disposed in corresponding passageways of the beads such that the beads are operable to transition between a constricted configuration and an expanded configuration. The contact surfaces of adjacent beads abut against each other in the constricted configuration. Adjacent magnets within adjacent beads generate an interactive magnetic field foxed on the abutting contact surfaces of adjacent beads.
