Abstract
A brake assembly for a steerable catheter that allows both dynamic locking and swapping between a locked mode of operation and an unlocked mode of operation is described. Dynamic locking enables fine adjustment of the catheter shaft position, while swapping between modes results in a more multipurpose catheter. Generally, the brake assembly includes a brake shoe positioned for slidable movement between a locked position contacting the steering dial and an unlocked position not contacting the steering dial. At least one spring biases the brake shoe toward the locked position. A catheter including a brake assembly is also described.
