Abstract
A catheter comprises a flexible polymer catheter body including a proximal shaft section and a distal working section, a wire support structure embedded within the distal working section of the catheter body, a proximal adapter mounted to the proximal shaft section of the catheter body, and a wire disposed within the catheter body. The wire has a proximal end and a distal end. The proximal end of the wire being operably connected to the proximal adapter, and the distal end of the wire is anchored to the wire support structure.

A steerable instrument, comprising:
- an elongate body comprising a shaft portion, a proximal section positioned distal to the shaft portion, a distal articulating section positioned distal to the proximal section, and a transition section longitudinally interposed between the distal articulating section and the proximal section;
- and a plurality of pullwires extending through at least the proximal section and the transition section of the elongate body, wherein the plurality of pullwires extend along a first lateral side of the elongate body within the proximal section, wherein the plurality of pullwires are coupled to the distal articulating section, wherein the plurality of pullwires are evenly angularly spaced apart from each other about a central longitudinal axis of the elongate body at the distal articulating section, and wherein the plurality of pullwires converge at a proximal end of the transition section, wherein the plurality of pullwires are configured to be tensioned to bend the distal articulating section in any direction without deflection of the proximal section.
A steerable instrument, comprising:
- an elongate body comprising a shaft portion, a proximal section positioned distal to the shaft portion, a distal articulating section positioned distal to the proximal section, and a transition section longitudinally interposed between the distal articulating section and the proximal section;
- and a plurality of pullwires extending through at least the proximal section and the transition section of the elongate body, wherein the plurality of pullwires extend along a first side of the elongate body within the proximal section, wherein the plurality of pullwires are coupled to the distal articulating section, wherein the plurality of pullwires are equally spaced circumferentially to each other at the distal articulating section such that the plurality of pullwires are equally spaced circumferentially at a distal end of the transition section and converge at a proximal end of the transition section, wherein the proximal section is configured to articulate, and wherein the proximal section and the distal articulating section are operable to be articulated independently relative to each other.
