Abstract
An apparatus for use in injectate delivery includes an actuator including a linkage, a force generating mechanism mechanically coupled to the linkage, and a controller coupled to the force generating mechanism. The force generating mechanism includes a passive force generator and an active force generator. In operation and on the basis of a control signal, the controller is configured to control the force generating mechanism to provide an input force to the linkage that is a combination of the first force provided by the passive force generator and a second force provided by the active force generator.
