Abstract
Components may be used separately or in combination to create anchoring systems for intra-luminal implants for the treatment of metabolic disorders such as obesity and diabetes. Various systems include an external component adapted for deployment around a portion of the gastrointestinal tract (e.g., the duodenum) and an internal component adapted for implantation within the gastrointestinal tract. Various systems use anchors that are based on mechanical interference, elasticity, spring force, shape memory transformation, magnetic attraction, repulsion and/or levitation. Various embodiments rely on longitudinal anchoring of the implants with minimal force against tissue.
