Abstract
A composite wire guide is formed from a more flexible distal wire guide and stiffer proximal wire guide. The flexible and stiff wire guides are joined by a connector that is tapered to provide a smooth transition between the distal and proximal portions. In other embodiments, wire guides may be joined by a joining ring, which may have a cross-section that is uniform, stepped, or tapered.
