Abstract
In one aspect, a valve actuation system includes a drive unit including an actuator configured to engage and move multiple valves disposed within a fluid cassette to selectively open and close each valve of the multiple valves and a positioning frame disposed adjacent the fluid cassette and along which the drive unit can be moved in three dimensions to align the actuator with a selected valve of the multiple valves.
