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.

Abstract: Embodiments herein relate to implantable systems for cancer treatment and related methods. In an embodiment, an implantable system for cancer treatment is included having a therapy output circuit configured to generate an electrical current for a plurality of electric field therapy electrodes to create one or more electric fields and control circuitry that causes the therapy output circuit to generate the one or more electric fields at frequencies selected from a range of between 10 kHz to 1 MHz within a bodily tissue. The control circuitry can be configured to select between operating in a first mode or a second mode of generating the electrical current for the electric field therapy electrodes based on a minimum electrical field strength threshold, wherein the first mode includes modulating amplitude of the electrical current and the second mode includes duty cycling of the electrical current. Other embodiments are also included herein.
