DRUG DELIVERY DEVICE
First Claim
1. A drug delivery device for injecting medicament, said drug delivery device comprising:
- a tubular reservoir for accommodating a medicament, said reservoir extending along a longitudinal axis;
a stopper slideably disposed in said reservoir;
a spring for moving said stopper from a first position to a second position in said reservoir;
at least one needle, said needle having a distal end for insertion into a patient, and a lumen extending proximally from said distal end, said lumen being in direct or indirect communication with said reservoir, wherein, at least a portion of said lumen extending proximally from said distal end extends along a reference axis not coaxial with said longitudinal axis;
a needle driver for displacing said needle from a first state to a second state; and
,an actuator, wherein activation of said actuator causes;
said spring to move said stopper from said first position and towards said second position; and
,said needle driver to displace said needle from said first state and towards said second state,wherein, said needle moves relative to, and separately from, said reservoir with said needle being displaced from said first state and towards said second state.

Abstract
The subject invention provides a drug delivery device for injecting medicament which includes: a tubular reservoir; a stopper slidably disposed in the reservoir; a spring for moving the stopper in the reservoir; at least one needle, the needle having a distal end for insertion into a patient, and a lumen extending proximally from the distal end, the lumen being in direct or indirect communication with the reservoir; a needle driver for displacing the needle; and, an actuator. 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.
