Abstract:
1. A self-adjusting clamp device to control weight loss by self-adjusting the gastric restriction stoma of a plicated stomach, said stomach having an anterior surface, a posterior surface, and a proximal stomach portion intermediate the gastroesophageal junction and said gastric restriction stoma, comprising: a. a frame comprising a first leg having an axis of elongation a first free end, a hinged end, and an axially extending inner surface; b. said frame further comprising a second leg in lateral spaced relationship with said first leg, said second leg having an axis of elongation, a second free end, a hinged end, and an axially extending inner surface, said frame further having a bight portion integrally connecting said hinged ends of said first and second legs so as to permit said first leg to articulate with respect to said second leg; c. latch means associated with said first and second legs for locking said first free end and said second free end in fixed lateral spaced relationship; d. lever means carried by said first leg responsive to distention and contraction of said proximal stomach portion for reducing and enlarging said gastric restriction stoma; and e. bias means associated with said lever means for biasing said lever means in continuous compressive engagement with at least a part of said anterior surface of said proximal stomach portion such that when said proximal stomach portion is distended by food said lever means in response to said distention will reduce said gastric restriction stoma and upon contraction of said proximal stomach portion will enlarge said reduced gastric restriction stoma.
