ABSTRACT:
A tube and stylet assembly for the controlled deflection of the tube is shown. The stylet is received in the lumen of the tube. The stylet includes a first filament having proximal and distal ends and a second filament having proximal and distal ends wherein the proximal and distal ends of the second filament are joined to the first filament such that a surface of the second filament abuts a surface of the first filament. Deflection of the first and second filaments along a plane substantially perpendicular to the abutting surfaces of the first and second filaments necessarily results in a corresponding, opposite deflection of the first and second filaments a spaced distance from the first deflection point. Therefore, a user can control deflection of one portion of the tube and stylet through manipulation of a second portion of the tube and stylet. This structure is particularly useful in inserting a gastric tube either nasally or orally.
