Abstract
For active control of steering, one or more motors integrated into an intra-cardiac echocardiography catheter handle control the bending. Multiple sets of motors may be used to control steering wires anchored at different segments along the catheter, allowing steering with multiple bends in complex patterns controlled by a controller. The handle may be releasably separated into a reusable motor part and a disposable steering wire part so that the more complex and expensive motor part is not discarded and so that the number of motors may be matched to the number of steering wires.
