1. A handle for a catheter, the catheter including a deflectable catheter section and a pull wire coupled to the deflectable catheter section, the handle defining a longitudinal axis and comprising:

  • a housing;

    a hub disposed within the housing and coupled to the pull wire;

    a deflection lever coupled to the hub and extending from a first side of the housing, the deflection lever movable between a first lever position in which the deflection lever extends away from the longitudinal axis at a first angle and a second lever position in which the deflection lever extends away from the longitudinal axis at a second angle less than the first angle; and

    a brake assembly coupled to the hub and rotatable between a first brake position in which the brake assembly applies a first resistance to rotation of the hub and a second brake position in which the brake assembly applies a second resistance to rotation of the hub greater than the first resistance,wherein movement of the deflection lever from the first lever position to the second lever position rotates the hub, pulling the pull wire to deflect the deflectable catheter section.
