Activation of the actuator causes the spring to move the stopper and the needle driver to displace the needle. The needle moves relative to, and separately from, the reservoir with the needle being displaced. Advantageously, with the subject invention, a drug delivery device is provided wherein a needle is moved, relative to the reservoir, in being displaced for injection. This permits control of the needle displacement separate from the reservoir. ## Claims ### Claim 1 A drug delivery device for injecting medicament, the drug delivery device comprising: a body; a reservoir movably disposed in the body for accommodating a medicament, the reservoir extending along a longitudinal axis; a needle, the needle having a distal end for insertion into a patient, and a lumen extending proximally from the distal end, the lumen being connectable with the reservoir, wherein, at least a portion of the lumen extends proximally from the distal end along a reference axis that is not parallel with the longitudinal axis; a first spring adapted to move the reservoir from a first reservoir position to a second reservoir position in the body to establish communication with the needle; a second spring; a needle driver adapted to displace the needle from a first state to a second state, the needle being disposed at an end of the needle driver; and a needle actuator displaced within the body relative to the driver by the second spring, wherein during its displacement, the needle actuator interacts with the needle driver to cause the needle displacement from the first state to the second state. ### Claim 2 (depends on 1) A drug delivery device as in claim 1, further comprising a device actuator; wherein activation of the device actuator causes: the first spring to move the reservoir from the first position and toward the second position; and the second spring to displace the needle actuator to cause the needle driver to displace the needle from the first state and toward the second state, wherein, the needle moves relative to, and separately from, the reservoir with the needle being displaced from the first state and toward the second state. ### Claim 3 (depends on 1) A drug delivery device as in claim 1, further comprising a flow channel in communication with the lumen of the needle, the flow channel being selectively communicable with the reservoir, wherein in an initial state, the flow channel not being in communication with the reservoir. ### Claim 4 (depends on 1) A drug delivery device as in claim 1 further comprising an adhesive for removably adherently securing the device to a patient. ### Claim 5 (depends on 1) A drug delivery device as in claim 1, wherein the needle driver includes a cantilevered arm, deformation of the cantilevered arm causing displacement of the needle from the first state and toward the second state. ### Claim 6 (depends on 1) A drug delivery device as in claim 1 further comprising an indicator for indicating that dosage delivery is complete. ### Claim 7 (depends on 1) A drug delivery device as in claim 1, wherein a window is formed in the body to permit viewing of at least a portion of the reservoir. ### Claim 8 (depends on 1) A drug delivery device as in claim 1 wherein, in the first state, the distal end of the needle is disposed within the body, and, wherein, in the second state, the distal end of the needle is exposed externally of the body. ### Claim 9 (depends on 1) A drug delivery device as in claim 1, wherein: the needle driver includes a first interacting feature; the needle actuator includes a second interacting feature; and during the needle actuator displacement, the first and second interacting features interact to displace the needle from the first state to the second state. ### Claim 10 (depends on 9) A drug delivery device as in claim 9, wherein the first interacting feature includes a detent; and the second interacting feature includes a ramp surface. ### Claim 11 (depends on 1) A drug delivery device as in claim 1, wherein: the needle driver includes a first interacting feature; the needle actuator includes a ramp; and during the needle actuator displacement, the ramp contacts the first interacting feature and a shape of the ramp and the interaction of the ramp and the first interacting feature displaces the needle from the first state to the second state.
