TORQUABLE GUIDING MEMBER SYSTEM

摘要

A catheter guidewire (500) configured for use in a body lumen to facilitate guiding of a catheter to a target location, including a thin elongate body o f material forming a guidewire, having a proximal end (504), a distal end (518 ), and a mid portion disposed therebetween, and a longitudinal axis; and the elongate body having a plurality of transverse cuts therein forming transver se beams (514) extending generally crosswise of the longitudinal axis and space d apart along the length of the body and axial beams generally parallel with t he longitudinal axis, the configuration increasing the lateral flexibility of t he body significantly more than it reduces the torsional stiffness thereof.
