The present invention provides a suspension vehicle and suspension formulations deliverable from an implantable delivery device. In particular, the suspension vehicle of the present invention allows the formulation of beneficial agent suspensions that are stable over time at ambient and physiological temperatures. In addition, the beneficial agent suspensions formed using the suspension vehicle of the present invention allow controlled delivery of beneficial agent from an implanted delivery device over sustained periods of time, even when such delivery occurs at low flow rates, through a small-diameter delivery channel. Also included in the present invention are implantable delivery devices.

The present invention includes devices and methods for reducing the start-up time of osmotically driven drug delivery systems capable of delivering a desired drug at a controlled rate over time. In particular, the present invention includes osmotic pumps that have a preloaded membrane, which includes a semipermeable material that has been preloaded with a nonaqueous, incompressible liquid filler that is miscible with water. The present invention further includes methods for making such osmotic pumps. The preloaded membranes included in the osmotic pumps according to the present invention have proven to provide significant decreases in average start-up times relative to osmotic pumps that include semipermeable membranes that are not preloaded.

The present invention includes materials and methods for providing vehicles useful for providing drug formulations that address the potential drawbacks of known nonaqueous formulations. In particular, the present invention includes nonaqueous vehicles that are formed using a combination of polymer and solvent that results in a vehicle that is miscible in water. The nonaqueous vehicles facilitate the formulation of drug formulations that are stable over time, even when stored at, or exposed to, elevated temperatures. Moreover, the miscible vehicles of the present invention allow the preparation of drug formulations that work to reduce the occurrence of partial or complete occlusions of the delivery conduits included in delivery devices used to administer the drug formulations.

An apparatus for and method of control of a switch (102) in an electrical power converter (100) using pulse width modulation to regulate output voltage (112) and current The method allows precise output voltage regulation to be achieved whilst accurately controlling the proportion of load-current supplied by multiple modules connected in parallel. A ramped waveform (408), consisting of a component representing the instantaneous current and a component representing the input voltage applied since the switch (102) switched on in the current PWM cycle, is compared with an error signal (406) to determine the width of each PWM pulse.
