Abstract
A process to load a medical device comprising a shape memory material into a delivery system is described herein. According to one aspect, the method includes applying a force to the medical device to obtain a delivery configuration thereof, where the device is at a first temperature within an R-phase temperature range of the shape memory material during application of the force. The medical device is cooled in the delivery configuration to a second temperature at or below a martensite finish temperature of the shape memory material. The force is then removed from the medical device, and the device is loaded into a delivery system. Preferably, the medical device substantially maintains the delivery configuration during the loading process.
