Abstract

A catheter handle includes a steering controller with a self-locking mechanism to be used in conjunction with a steerable catheter shaft. A compression spring portion of the self-locking mechanism is located between the steering controller and a handle shell and causes alternating protrusions and recesses on the steering controller and on the handle shell to engage, thus locking the steering controller into a fixed position with the handle shell. Through a single-handed operation, an operator enables steering controller rotation by applying a force to the steering controller, which disengages the steering controller from the handle shell. The operator then adjusts the profile of a distal-end region of the catheter by rotating the steering controller. When the desired profile of the distal-end region of the catheter has been obtained, the operator removes the force from the steering controller and the spring decompresses to reengage the steering controller with the handle shell.
