First Claim
Patent Images
1. A handle apparatus for use with a steerable device including a steerable device body and steering wire, the handle apparatus comprising:
- a handle body adapted to be secured to the steerable device body and defining a proximal end, an inner chamber, a proximal aperture and a distal aperture;
a trolley member slidably located at least partially within the inner chamber and adapted to be connected to the steering wire, the trolley member defining a trolley member lumen substantially aligned with the handle body proximal and distal apertures; and
a steering member rotatably coupled to handle body and operably connected to the trolley member such that rotation of the steering member axially repositions the trolley member, the steering member including a steering member lumen substantially axially aligned with the trolley member lumen and a knob defining a distal end that is proximal to the proximal end of the handle body.

Abstract
A handle apparatus includes a handle body, a trolley member that may be secured to a steering wire, and a steering member operably connected to the trolley member. Rotation of the trolley member is prevented and rotation of the steering member axially repositions the trolley member and steering wire.
