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.
