A system and method for manufacturing a medical device. The system can include a thermal chamber and an expander at least partially positioned within the thermal chamber. The expander can be configured to uniformly expand a medical device as the medical device is advanced over the heated expander and heat set the expanded medical device while the medical device is positioned on the heated expander. The method can include forming a medical device from a tube having a first diameter uniformly expanding the medical device from the first diameter to a second diameter at which the medical device can be left within a body vessel, the medical device being expanded from the first diameter to the second diameter while being continuously positioned on an expander and heat setting the expanded medical device at the second diameter while the medical device is positioned on the expander.
