PRESSURE-SENSING GUIDEWIRE HAVING IMPROVED TORQUE

摘要

A pressure-sensing guidewire assembly with improved stiffness and torquabili ty is disclosed. The guidewire assembly includes an elongated tubular member having a lumen extending therethrough. The lumen receives a torque enhancing mandrel that adds stiffness and torquability to the elongated tubular member . The torque enhancing member and elongated tubular member may have an astraumatic spring tip.
