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.
Claims20
A gastrointestinal implant system for treating metabolic disorders including diabetes and obesity, the system comprising:
- a tubular implant adapted for placement within at least a portion of a duodenum, the tubular implant having a securing feature;
- and
- an external band configured for implantation around at least one of a pylorus, and the duodenum, the external band having a coupling feature for removably engaging and coupling with the securing feature of the tubular implant, without penetrating the duodenum or pylorus, such that the tubular implant resists migration within the gastrointestinal tract, and the external band having an implanted inner diameter generally equal to a corresponding outer diameter of the duodenum or pylorus;
- wherein the securing feature and coupling feature are configured such that the tubular implant is releasably coupled to the external band to facilitate removal of the tubular implant.
A modular gastrointestinal implant system for treating metabolic conditions including diabetes and obesity, the system comprising:
- an external implant configured for affixing around at least a portion of a duodenum or pylorus, the external implant having a docking feature;
- and
- a therapeutic implant adapted for placement within a gastrointestinal tract, the therapeutic implant having a securing feature adapted to removably couple with the docking feature without penetrating the gastrointestinal tract, such that the therapeutic implant resists migration within the gastrointestinal tract;
- wherein the external implant has an implanted diameter equal to an outer diameter of the duodenum or pylorus.
A method of treating metabolic conditions including diabetes and obesity, the method comprising:
- placing an external implant around at least a portion of a duodenum, the external implant having a docking feature and the external implant having an inner diameter generally equal to an outer diameter of the corresponding portion of the duodenum;
- implanting, using a minimally-invasive technique, an internal tubular implant having a securing feature to a location within the duodenum corresponding to the location of the external implant;
- and
- causing the securing feature to removably couple with the docking feature without penetrating the duodenum.
