Abstract
A drive assembly for use with a delivery catheter for delivering an implantable medical device includes a drive motor configured to be operably coupled to an inner shaft of the delivery catheter such that operation of the drive motor causes the inner shaft to translate relative to the outer shaft and a controller. The controller is configured to receive a position signal from a position sensor indicating a position of the implantable medical device relative to the outer shaft as well as a motor signal indicating a rotational position of an output shaft of the drive motor. The controller is configured to output a control signal instructing operation of the drive motor based upon the indicated rotational position of the output shaft of the drive motor and the indicated position of the implantable medical device relative to the outer shaft.
