CORONARY GUIDEWIRE SYSTEM

摘要

A guidewire system configured for introduction into a body lumen, comprising a core wire having proximal end and a distal end and a tapering profile, and a micromachined tube coupled to the core wire, and a joint where the micromachined tube is joined to the core wire; the location of the joint being at alocation on the tapering profile where the torsional force which can be transferred by the core wire and the micromachined tubing are substantially the same.
