Abstract:
1. A catheter control handle, comprising: a housing having an elongate catheter extending therefrom; a spherical ball pivot supported within the housing; a steering ring which is shaped to circumferentially encircle a portion of the housing, the steering ring being supported via one or more support members extending radially from the spherical ball pivot; one or more pullwires attached to the steering ring whereby manipulation of the steering ring in a first direction urges a distal steerable section of the catheter to articulate in a corresponding first direction; one or more compression coils, wherein each of the compression coils surrounds a corresponding pullwire, couples to a proximal end of the catheter, and extends to a transition manifold located distal to the spherical ball pivot; and wherein the housing comprises a proximal handle portion extending therefrom, the proximal handle portion comprising a proximal section control to bend a proximal steerable section located proximal to the distal steerable section; wherein the proximal section control is further configured to bend the proximal steerable section in a single plane by rotating the proximal section control around a longitudinal axis of the handle portion.
