Abstract
A control device and mechanism for deploying a self-expanding medical device includes an actuating mechanism which allows the user to retract a restraining sheath from the self-expanding medical device by using a motion that is in angle to the line of motion of the restraining sheath, which helps prevent movement of the catheter portion of the control device within the patient. The control mechanism allows the physician to obtain a longer retracting stroke to the restraining sheath with a shorter actuating motion reducing the amount of manual actuation needed to be performed by the physician when retracting the sheath. The control mechanism can also reduce the amount of actuating force needed to retract the restraining sheath by utilizing springs or biasing members in connection with the actuating mechanism which combines with the actuating force supplied by the physician to cause the retraction of the restraining sheath.
