Abstract: A kit for implantation of an implantable medical device (IMD) comprises an elongated outer shaft, a tether, and an elongated inner shaft. The IMD comprises a fixation element comprising a looped portion. The outer shaft is sized to traverse a vasculature of the patient and defines a longitudinal lumen and a port in fluid communication with the lumen and located proximal a distal end of the outer shaft. A first portion of the tether is configured to pass through the lumen. A second portion of the tether is configured to exit the lumen through the port and pass through the looped portion of the fixation element of the IMD outside of the outer shaft. A third portion of the tether defines a looped portion of the tether. A portion of the inner shaft is configured to pass through the lumen and to pass through the looped portion of the tether.

Abstract: A system includes a delivery catheter and a separately-packaged implantable medical device assembly. The assembly includes a relatively compact implantable medical device, a support shaft, a tether, and a snare mandrel. The tether, which extends in the support shaft, has a distal portion coupled to the device, at a distal end of the support shaft, and a proximal portion protruding from a proximal end of the support shaft, for engagement by a hook of the snare mandrel. An operator may use the engaged snare mandrel to pull the support shaft into a lumen of an inner shaft of the catheter so that the coupled device comes into engagement with a flared end of the catheter inner shaft. Then, after locking the proximal portion of the tether within the catheter, the operator may advance a receptacle of the catheter over the device.

Abstract: A delivery system for an implantable medical device includes a tool and a tethering member extending side-by-side within an inner shaft thereof; the tool extends within a first lumen, being in sliding engagement therein, and includes a distal end coupling feature that protrudes from a distal end of the inner shaft; and the tethering member has a first segment extending within a second lumen, and a second segment extending from the first segment and distally from the distal end of the inner shaft to an end of the tethering member, which is configured to engage with a holding member of the device, and with which the coupling feature of the tool is configured to couple. A retainer may be joined to another end of the tethering member that protrudes from a proximal port of the system.
