Abstract
A delivery system for an implantable medical device includes an outer shaft defining an outer shaft lumen and an inner shaft translatable within the outer shaft lumen, the inner shaft defining a lumen extending through the inner shaft. An actuation mechanism extends through the lumen 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. The force translation rod includes a transition in electromagnetic permeability. The delivery system includes an inductive coil disposed relative to the force translation rod and positioned to detect a change in inductance resulting from the transition in electromagnetic permeability passing through the inductive coil.
