11. A system for restricting a cross-sectional area of a cavity formed by a stomach wall, said system comprising:
-
a catheter comprising a passage extending therethrough;
a first member initially positioned within said passage and movable with respect to said catheter along a length of said passage;
a first fastener extending from a proximal end of said first member, said first fastener movable between a retracted configuration and a deployed configuration, wherein in said retracted configuration said first fastener at least partially disposed within said passage, and in a deployed configuration said first fastener attached to a first portion of the stomach wall;
a second member initially positioned within said passage and movable with respect to said catheter along a length of said passage;
a second fastener connected to a proximal end of said second member, said second fastener movable between a retracted configuration and a deployed configuration, wherein in said retracted configuration said second fastener at least partially disposed within said passage, and in a deployed configuration said second fastener attached to a second portion of the stomach wall. - View Dependent Claims (12, 13, 14, 15, 16, 17, 19, 20)
