Abstract

A guidewire system is disclosed having a core wire (501) with a tapering profile, and a micromachined tube (514) joined to the core wire (501) at a location on the tapering profile where the torsional force which can be transferred by the core wire (501) and the micromachined tube (514) are substantially the same.
