Merit Laureate® Hydrophilic Guide Wire The Merit Laureate hydrophilic guide wire is particularly useful to position the devices during diagnostic and interventional procedures. It has extraordinary torque control, turn-for-turn responsiveness, and improved lesion crossability. This helps in providing high performance to navigate tortuous vessels. The Merit Laureate hydrophilic guide wire is hydrophilic coated. Hence, it provides good lubricity and constant surface coating adhesion. The Laureate is particularly used to minimize wire whipping, reduce friction, and to support rapid catheter exchanges.
