摘要： 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.

摘要： A needle free injection device for use with a cartridge containing an injectate includes a housing. The housing includes an end wall at its distal end and an inner wall. The inner wall extends in a direction from the proximal end of the housing to the distal end of the housing and separates a first chamber from a second chamber in the housing. The housing includes a first opening disposed in the end wall and is in fluid communication with the first chamber. The housing includes a second opening is in fluid communication with the second chamber. A coupler is disposed in the first chamber for coupling to the cartridge. The first opening and the second opening are in fluid communication via a channel for transfer of fluid between the first chamber and the second chamber.

摘要： An apparatus for transdermal injection includes a collet configured to transition between first and second states. In the first state, the collet receives a cartridge with a predetermined elongate shape. In the second state, an inner surface of the collet substantially conforms to the predetermined elongate shape of the cartridge such that expansion of the cartridge, when the cartridge is pressurized, is substantially uniformly opposed.
