1. An apparatus for preparing and loading an endovascular shunt assembly into a delivery catheter, the endovascular shunt assembly including a shunt body and a malecot attached to a distal end of the shunt body, the apparatus comprising:
a guide base comprising a plate having a plurality of guide slots extending longitudinally along the plate from a bottom end of the plate, each of the guide slots following a respective predetermined path configured to guide lateral movement of a respective guide boss; and
a drive carriage slidably mounted to the guide base, the drive carriage including a frame extending laterally across the guide base, the drive carriage comprising a plurality of guide bosses slidably mounted to the frame such that each guide boss is configured to move laterally relative to the guide base, each guide boss having a respective guide pin inserted into a respective guide slot such that the respective lateral position of each guide boss follows the path of the respective guide slot as the drive carriage is moved longitudinally relative to the guide base,
wherein the plurality of guide bosses includes a transfer tube guide boss which retains a transfer tube into which the endovascular shunt is loaded by operation of the endovascular shunt loader, and
wherein the guide slots are configured to move the respective guide bosses as the drive carriage is moved longitudinally relative to the guide base to load the endovascular shunt into the transfer tube.
