An implantable medical device has a portion formed from a shape memory alloy (SMA) and adapted to connect to another device. At a lower temperature, the SMA is deformed such that the two devices may be mated with low insertion force. At a higher temperature, e.g., the internal temperature of the human body, the SMA attempts to return to its original shape, creating a connection between the two devices and causing a retention force that resists disconnection of the two devices.
