US 2011/0087287 A1 · Rod-to-Rod Connector

Abstract

A rod-to-rod connector assembly comprising a longitudinal member, which may be straight or S-shaped or have some other configuration; and a connecting member connected to a first end of the longitudinal member, wherein the connecting member comprises a pair of threaded opposed ends defining a channel therebetween. The assembly may further comprise a threaded blocking mechanism that engages the pair of threaded opposed ends of the connecting member. Preferably, the longitudinal member connects to only one of the opposed ends of the connecting member. The longitudinal member may comprise a first elongated portion comprising a first longitudinal axis; a second elongated portion comprising a second longitudinal axis; and a curved portion connecting the first elongated portion to the second elongated portion, wherein the first longitudinal axis and the second longitudinal axis are parallel to one another.
