Abstract
An implantable device uses shape memory alloy (SMA) as the driver to compress a reservoir thereby providing a constant pressure source fluid delivery device. The SMA may form either the reservoir itself by appropriate shaped sheets or it may form bands around a flexible reservoir member. The reservoir may also be formed of rigid members pivoted or clamped using SMA actuators to bias the rigid members together.
