Abstract
Devices and methods for powering a medical device for sustained delivery of fluids or continuous monitoring of body analyte. The devices may comprise a pumping mechanism, a driving mechanism for activating the pumping mechanism to dispense fluid, and a power source coupled to the driving mechanism and having an energy storage cell for providing a pulsed power to the driving mechanism. The methods may be implemented by activating the driving mechanism using pulsed energy in the form of at least one pulse train pattern accumulated in and discharged from an energy storage component.

38. A method for powering a medical device delivering fluid to a body of a patient, the method comprising:
-
providing a medical device, the device including; a pump for dispensing a fluid; a stepper motor for activating the pump; and a power source for charging an energy storage component; accumulating energy in the energy storage component during a first period of time; and discharging the energy from the energy storage component and providing the energy to the stepper motor in a form of pulsed power, during a second period of time. - View Dependent Claims (39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54)
