Abstract
A drug delivery device is provided herein, the device including a reservoir for containing a medicament. The medicament includes a suspension of solids in a liquid carrier. The device also includes a needle having a distal end for injection into a patient, a proximal end in communication with the reservoir, and a lumen extending between the distal and proximal ends. A path is defined from the reservoir to the distal end of the needle through the lumen, the path having an inner diameter that decreases in a proximal to distal direction along at least a portion thereof. Advantageously, with the subject invention, a flow path may be defined which provides a more gradual transition in diameter from the reservoir to a distal tip of the needle. In this manner, changes in velocity of the suspension may be less abrupt than in the prior art, thus better maintaining solid particles in the suspension.
