A stent expansion device includes an expanding mandrel having a side, a threaded internal channel, two open ends and a plurality of longitudinal slots along the side. An expansion pin is included, and has a cylindrical body with a threaded tapered portion. The device is configured to expand a stent by rotating or screwing the tapered portion of the expansion pin within the internally treaded mandrel. A method of expanding a stent in a controlled fashion using the stent expansion device is also described.
