Abstract:
1. A method for treating a patient having a metabolic related disorder, said method comprising: deploying an implant within a gastrointestinal tract of the patient so that a proximal end of an anchor of the implant is disposed within a stomach of the patient while a distal end of the anchor is disposed distal of a pyloric valve of the gastrointestinal tract, the anchor having a proximal atraumatic feature at the proximal end and a distal atraumatic feature at a distal end with an elongate element extending therebetween, wherein the distal atraumatic feature comprises a distal portion that engages against a mucosal surface of the duodenum and remains entirely distal of the pyloric valve so as to maintain the distal end within the duodenum distal of the pyloric valve when the implant is deployed; supporting a sleeve of the implant with the anchor so that the sleeve extends along an intestine of the patient, and so that a flow including ingested matter enters a lumen of the sleeve from the stomach, the flow being in contact with a wall of the stomach; inhibiting advancement of the anchor around a bend of the intestine near the stomach by engaging a proximal portion of the anchor against a surface area of a mucosa of the stomach, by engaging the distal portion of the distal feature of the anchor against a mucosal surface area of the duodenum, and by resisting bending of the elongate element between the proximal and distal ends; and advancing the flow along the intestine within the lumen of the sleeve, the ingested matter comprising ingested nutrients and particles of food.
