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.
