Abstract

A steerable catheter or sheath control handle for steering a distal end of a tubular catheter body or sheath body having first and second actuation wires extending from a proximal end of the body comprises a grip portion, a bearing assembly, and an actuator. The first grip potion includes a pivot and an actuation wire pathway. The bearing assembly is located on the grip portion proximal to the pivot. The actuator is pivotally coupled to the pivot and includes first and second ends that are on opposite sides of the centerline from each other. When the distal end of the handle is coupled to the proximal end of the body, the first and second actuation wires extend along the pathway to the bearing assembly. The bearing assembly diverts the first actuation wire to a first connection point on the actuator and the second actuation wire to a second connection point on the actuator.
