Abstract: A system for delivering an implantable medical device includes a handle housing. An outer sheath is coupler secured to a proximal end of an outer sheath that is configured to cover at least a portion of the implantable medical device. An outer sheath drive assembly is operably coupled to the outer sheath coupler and is configured to translate the outer sheath relative to the handle housing. An actuation shaft coupler is secured to a proximal end of an activation shaft. An actuation shaft drive assembly is operably coupled to the actuation shaft coupler and is configured to cause the actuation shaft to translate relative to the handle housing and shift the implantable medical device from a first position and a second position in which the implantable medical device is radially expanded relative to the first position.

Abstract: A delivery system for an implantable medical device includes an outer shaft and an inner shaft translatable within the outer shaft. An internally exposed coil is disposed within the inner shaft and is electrically coupled to an externally exposed coil that can be used to inductively transmit a current flowing through the internally exposed coil. An actuation member extends within the inner shaft and includes a coupler, a force translation rod that extends proximally from the coupler and a plurality of push pull rods that extend distally from the coupler and that releasably couple to the implantable medical device. As the force translation rod moves relative to the internally exposed coil, an impedance varies in accordance with relative position.

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.
