Abstract
A guiding sheath has a braided layer for improved deflection characteristics and ring electrodes for electrical sensing, mapping and visualization, wherein lead wires for the ring electrodes are passed through lumened tubing position under the braided layer in a proximal portion of the guiding sheath shaft and above the braided layer in a distal portion of the guiding sheath shaft. Moreover, the hemostatic valve includes an improved friction ring with air vents to reduce the risk of air being introduced into the valve.
