Abstract:
1. A catheter handle for steering a catheter shaft having a proximal end and a distal end and at least two elongate steering elements, each steering element having a distal end region secured at or near the distal end of the catheter shaft, and each steering element having a proximal end, the catheter handle comprising: a catheter handle housing attached to the proximal end of the catheter shaft; a steering mechanism attached to the proximal end of each of the steering elements and moveable from a first position to a second position to deflect the distal end of the catheter shaft, the steering mechanism including: a first control knob configured to rotate about a first axis; and a second control knob configured to rotate about the first axis; and a locking mechanism moveable between an unlocked position and a locked position to cause at least one member fixedly attached to at least one of the two elongate steering elements to translate along the first axis, thereby restricting movement of the steering mechanism when in the locked position.
