摘要：
The present disclosure provides a medical device comprising an actuator restraining assembly configured to assist in restraining a catheter shaft in a deflected configuration. The actuator restraining assembly may include a brake element, a release element, a connecting sheath, and a connecting rod disposed in a catheter handle, wherein the connecting sheath and connecting rod are attached to an actuator mechanism, and wherein the at brake element is attached to the connecting sheath and the release element is attached to the connecting rod. The brake element is sized and configured to contact an inner wall of the handle to thereby provide resistance to movement of actuator mechanism in a proximal direction with respect to the handle. In one embodiment, the actuator restraining assembly is configured to allow for temporary, i.e., reversible, restraining of the catheter shaft in the deflected configuration.
