摘要：
A gastrointestinal implant device comprises a proximal element configured to reside in a stomach to resist distal migration； a distal element configured to reside in an intestine to resist proximal migration, and one or more tethers coupling the proximal element to the distal element. The distal element comprises a wave anchor and a surface roughness element on a surface of at least a portion of the wave anchor. Delivery systems and retrieval techniques are also provided.
