Claim Text:
1. A catheter shape adjustment mechanism, comprising: a catheter handle comprising an elongate handle body having a proximal end and a distal end with a passage extending between the proximal end and the distal end; a stylet carrier displaceably mounted in the passage of the elongate handle body, at least a component of a multi-component stylet mounted to the stylet carrier, wherein a distal part of the stylet has a non-rectilinear shape; a shape adjuster rotatably carried on an exterior of the elongate handle body, the shape adjuster being rotatable about a longitudinal axis of the elongate handle body; a steering control mechanism displaceably carried by the elongate handle body, the steering control mechanism configured to effect cause deflection of the multi-component stylet proximal to the distal part of the stylet having the non-rectilinear shape; complementary guide formations carried by the stylet carrier and the shape adjuster, wherein the stylet carrier is in the form of a slide, the slide axially slidable in the elongate handle body such that rotary motion applied to the shape adjuster imparts an axial displacement to the stylet carrier to adjust a shape of a distal part of the multi-component stylet, in use.
