Abstract

Apparatus for peroral treatment of morbid obesity includes a collapsible intra-gastric appliance which can be temporarily deformed to pass through the esophagus and cardiac opening of the stomach and to autogenously assume a normal shape after it is received in the stomach to stimulate neuro-receptors in the sub-mucosa of the gastric fundus. Means are provided for detachably connecting the appliance to the lower end of an elongate, semi-rigid inserter rod which is passed through an aperture formed in the appliance to effect the detachable connection. Downward pressure on the inserter rod forces the collapsed appliance through the esophagus and cardiac opening into the stomach and slight upward force of the inserter rod is thereafter applied to detach the rod from the appliance.

Claims

1. Apparatus for peroral treatment of morbid obesity comprising a collapsible intra-gastric appliance, said appliance being a collapsible, hollow, shaped device which is

normally shaped and dimensioned to be received and retained within the fundus without deforming the stomach walls beyond its normal shape and dimensions,

formed of a semi-rigid skeleton which is collapsible by the application of external force to deform said device to a shape and cross-sectional dimension which is insertable into the stomach through the esophagus and the cardiac opening, and

capable of autogenously reassuming and retaining said normal shape when such collapsing external force is removed,

said appliance also including

(a) means for detachable connection to the lower end of an elongate semi-rigid inserter rod, and

(b) means defining an aperture in said appliance through which said rod can be passed to effect such detachable connection.
