1. A method of priming an interventional device assembly, comprising:
providing the interventional device assembly, the interventional device assembly comprising a first interventional device coupled to a first hub and a second interventional device coupled to a second hub arranged in a concentric stack, the second interventional device being positioned within a lumen of the first interventional device, wherein the first hub is configured to axially translate to axially translate the first interventional device relative to the second hub and the second interventional device, and wherein the second hub is configured to axially translate to axially translate the second interventional device relative to the first hub and the first interventional device;
coupling the interventional device assembly to a drive system while arranged in the concentric stack;
axially advancing the first interventional device and the first hub relative to the second hub to decrease a depth of insertion of the second interventional device within the lumen of the first interventional device while maintaining a distal end of the second interventional device within the lumen of the first interventional device; and
flushing the first interventional device with fluid after decreasing the depth of insertion of the second interventional device within the lumen of the first interventional device.
