The disclosure describes techniques and systems for delivering an implantable medical device. In one example, an implantable medical device (IMD) delivery system may include an elongated member comprising a first distal end configured to mate with the IMD, a resilient member disposed along at least a portion of the elongated member, a housing configured to accept a first proximal end of the elongated member and a second proximal end of the resilient member, a rotation control mechanism wherein user movement of the rotation control mechanism causes rotation of the elongated member with respect to the housing and a fixation element of the IMD into tissue, and a deflection control mechanism wherein user movement of the deflection control mechanism causes longitudinal displacement of the resilient member along a longitudinal axis of the elongated member and the housing resulting in angular deflection of the first distal end of the elongated member.

Medical device delivery system

An implantable medical device is tethered to a delivery catheter by a length of a tether, which extends through an attachment feature of the device and between a free end thereof and a secured end thereof, wherein the secured end is fixedly coupled to a tubular member of the catheter in proximity to a distal end thereof, and the free end is engaged against an inner surface of a sidewall that extends within the tubular member. The free end of the tether may be engaged against the inner surface by an enlarged distal tip of an elongate wire that extends within a lumen defined by the inner surface of the sidewall. An operator may move the distal tip of the wire out through a distal opening of the lumen, thereby pushing the free end of the tether out from engagement with the surface, to untether the device from the catheter.
