Drug delivery device
First Claim
1. A drug delivery device which comprises:
- a. a reservoir for the drug, having a discharge outlet towards one end thereof through which the drug can be discharged, b. a drive member which is arranged in the device to act against the reservoir directly or indirectly to cause the volume of the reservoir available for the drug to be reduced and to cause drug in the reservoir to be discharged from the reservoir at the end in which the discharge outlet is located, c. a flow controller which controls flow of the drug through the discharge outlet, the flow controller comprising a close-packed array of elongate rod members extending generally in the direction in which the drug flows out of the reservoir.

Abstract
A drug delivery device which can be implanted in a patient, includes a reservoir for the drug with at least one dis-charge outlet through which the drug can be discharged. A drive member comprising a shape memory alloy is arranged in the device in a deformed configuration to act against the reservoir directly or indirectly by recovering from its deformed configuration by virtue of its elastic properties to cause the volume of the reservoir available for the drug to be reduced and to cause drug in the reservoir to be discharged from the reservoir. A flow controller for controlling the flow of the drug through the discharge outlet comprises a close-packed array of elongate rod members extending generally in the direction in which the drug flows out of the reservoir.
