The passage of food through a stomach (S) is restricted by clamping an apparatus (10) around the stomach (S). The apparatus (10) comprises cooperating jaws (12, 14) having stomach engaging surfaces (22, 24). The stomach engaging surfaces (22, 24) define a relatively open area (26) which permits the passage of food therethrough at a restricted rate. The stomach engaging surfaces (22, 24) further define relatively closed areas (28, 30) which prevent the passage of food therethrough. The apparatus (10) is secured in place on the stomach (S) by cooperating teeth (36) which engage the stomach wall, and by sutures formed between the stomach wall and apertures (38, 40, 42) formed in the jaws (12, 14).
