    Abstract: A deflectable catheter shaft section is disclosed comprising an elongated body extending along a longitudinal axis and comprising a distal end and a proximal end; and a plurality of lumens extending along the longitudinal axis of the elongated body, wherein at least one of the lumens is abutting at least another one of the lumens. A catheter comprising the deflectable catheter shaft section and a method of manufacturing the deflectable catheter shaft section are also disclosed. A catheter incorporating a deflectable catheter shaft section can further comprise first and second compression coils disposed over pull wires located within the catheter, wherein the compression coils are unattached to the catheter or components thereof, but can be constrained by a shaft coupler at a distal end of each of the compression coils and by at least a portion of a handle assembly at a proximal end of each of the compression coils.

    Abstract: Catheter actuators providing a mechanical advantage are disclosed. The actuators include a pull wire arm guide plate and a drive wheel attached around the pull wire arm guide plate and pivotable relative to the guide plate, the drive wheel comprising at least one thumb boss for pivoting the drive wheel about a drive wheel axis of rotation. The drive wheel mechanically engages at least one pull wire arm slidably mounted in a pull wire arm channel in the pull wire arm guide plate. A mechanism transfers drive wheel input into longitudinal motion of the at least one pull wire arm. The mechanism may include, for example, a pin pushing against a bendable pushing member riding in an arcuate pin groove in a top surface of the guide plate, or a pin pushing against a surface of a cam arm pivotably mounted on the top surface of the guide plate.
