Stylet device for guiding an enteral feeding tube
First Claim
1. A stylet for use with a feeding tube, said stylet comprising:
- (a) a stylet hub defining a bore therethrough and constructed for attachment to one end of a feeding tube, said stylet hub having an inner surface;
(b) a longitudinally extending reinforcement member having a proximal end; and
(c) a retaining member having an outer surface and defining an aperture therethrough, said retaining member disposed in said bore defined by said stylet hub, said proximal end of said reinforcement member disposed between said outer surface of said retaining member and said inner surface of said stylet hub, said retaining member outer wall and said inner surface of said stylet hub constructed to retain said reinforcement member therebetween through an interference fit.

Abstract
The present invention is an improved stylet for a enteric or nasoenteric feeding tubes. In broadest terms, the present invention comprises: a stylet for a feeding tube, the stylet having: (a) a stylet hub having a bore therethrough and adapted to be attached to one end of the feeding tube, the bore having an inner surface; (b) a longitudinally extending reinforcement member adapted to extend through the feeding tube, the reinforcement member having a proximal end; and (c) a hollow member having an outer surface and having an aperture, the hollow member disposed in the bore so as to hold the inlet end of the reinforcement member between the outer surface and the inner surface through an interference fit.
