Abstract: Medical devices and methods for making and using medical devices are disclosed. An example system for delivering an implantable medical device includes an outer shaft and an inner catheter, each having a proximal end, a distal portion and a lumen extending therein, wherein the inner catheter extends within a portion of the outer shaft lumen. The system also includes an actuation shaft extending within a portion of the inner catheter lumen, wherein a distal end of the actuation shaft is coupled to the implantable medical device. The system also includes a guidewire shaft extending within a portion of the inner catheter lumen and a coupling component including a distal end region, a proximal end region and a length, wherein the actuation shaft and the guidewire shaft are coupled to the coupling component such that actuation of the coupling component translates the actuation shaft and the tubular guidewire shaft simultaneously.

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: Various embodiments are generally directed to positioning techniques to facilitate entry of a flexible elongate member (e.g., endoscopic accessory tool) into and/or through selected anatomies, such as by directing a set of positional controls based on feedback from a set of transducers to achieve or maintain a position within a body lumen, for instance. Some embodiments are particularly directed to a feedback loop for positioning or guiding a flexible elongate member into a target configuration for one or more of inspection, orientation, and/or facilitating access to body passageways. In one embodiment, for example, a device manager may include circuitry to operate at least one positional control in a set of positional controls based on data indicative of a current configuration of a flexible elongate member generated by a set of transducers.
