Title: MRI COMPATIBLE HANDLE WITH STEERABLE SHEATH AND NEUTRAL POSITION INDICATOR
Abstract:
An MR compatible deflectable catheter is provided. The MR compatible deflectable catheter includes a steerable sheath having a tubular shaft. The tubular shaft receives first and second longitudinal movement wires at a distal end thereof and an audible or tactile means for indicating to a user the degree of deflection of the distal tip of the steerable sheath. A control handle is coupled to a proximal end of the first and second longitudinal movement wires and causes longitudinal movement of the wires. The control handle contains windows that reveal symbols, which indicate the direction of distal curve deflection, the amount of distal curve deflection, the neutral position of the distal curve.
