Fluid Delivery System With Needle Assembly

Abstract: A needle assembly configured to be part of a drug delivery device comprises a plurality of extendable and retractable needles. The needles are fluidly coupled by a flexible connector, which is configured to maintain fluid connection between the needles throughout their movement. When the needles are extended, a first needle pierces a patients skin, and a second needle pierces a septum of a drug cartridge to deliver a medication. Once the medication has been delivered, the needles may then retract within a needle assembly housing. The needle assembly may also be part of a partially disposable drug delivery device and may be used with multiple different drug cartridges. Multiple embodiments of the needle assembly are disclosed.
