Column filter retainer connector with structural reinforcement and biocompatible fluid passageway

摘要

A connector with a biocompatible fluid passageway to be used as a column filter retainer and the method for manufacturing it is described. The connector has a reinforcement insert and a biocompatible molding covering portions of the reinforcement insert. The reinforcement insert has a first portion, a second portion, and a middle portion between the first portion and the second portion. The first and second portions have threaded sections and each have a plurality of non-threaded sections. For a given portion, the junction of the non-threaded sections forms a lip by which to prevent the molded material from flowing into the threaded sections. In certain embodiments, an interior web is used in the reinforcement insert to provide additional structural support.
