摘要:
A guiding sheath has a braided layer for improved deflection characteristicsandring electrodes for electrical sensing, mapping and visualization, whereinlead wires forthe ring electrodes are passed through lumened tubing position under thebraided layer ina proximal portion of the guiding sheath shaft and above the braided layer ina distalportion of the guiding sheath shaft. Moreover, the hemostatic valve includesan improvedfriction ring with air vents to reduce the risk of air being introduced intothe valve.
