A transdermal drug delivery device includes a reservoir, a transdermal membrane, a piston, a control rod, a spring, and a rotational cam. The reservoir is configured to hold a formulation. The transdermal membrane is configured to allow the formulation from the reservoir to pass therethrough. The piston is configured to move into the reservoir. The control rod is attached to the piston and includes a plurality of teeth thereon. The spring is configured to apply force to the control rod in the direction of the reservoir. The rotational cam has a first camming surface and a second camming surface that are configured to engage with the plurality of teeth. The rotational cam, when rotated, is configured to disengage the first camming surface from a first tooth of the plurality of teeth, thereby allowing the spring to advance the piston into the reservoir to expel the formulation onto the transdermal membrane.

Transdermal drug delivery devices and methods

A two-part bioactive agent delivery system, the system including a disposable part comprising an agent reservoir, a bolus chamber, the volume of the bolus chamber being less than the volume of the agent reservoir, an agent outlet, and a valve having a first position communicating the agent reservoir with the bolus chamber and a second position communicating the bolus chamber with the outlet; and a reusable part including a valve driver, a power source and control electronics, the control electronics being adapted to control the valve driver to actuate the valve to deliver bioactive agent from the agent reservoir to the agent outlet; the system further having a spring extending between the agent reservoir piston and a surface of the reusable part or of the disposable part to pressurize the agent reservoir when the spring is compressed and the agent reservoir contains a quantity of bioactive agent.
