A modular system for therapy within a gastrointestinal system. The system includes anchoring or attachment functionality (110) embodied in a low-profile implant technology (111) and removable therapy components, which can be reversibly attached to these low-profile implants to accomplish various therapies. This modular design allows the physician to tailor the therapy to the patient's needs. The modular system has the potential to create conduits for diversion and/or restriction of food and organ secretions and to facilitate the treatment of metabolic disorders such as obesity and T2DM.
