摘要：
An implantable restriction device includes a plurality of beads, a plurality of links joining the beads together, and a parking feature. Each bead in the plurality of beads includes a housing, a passageway extending through the housing, and at least one magnet disposed around the passageway. The plurality of links are slidably disposed in corresponding passageways of the beads such that the plurality of beads can transition between a constricted configuration and an expanded configuration. The parking feature can consistently position the at least one link relative to the housing in the contracted configuration.
