#$%^&*AU2017203997A120170706.pdf#####30 ABSTRACT An insertion mechanism having a vented fluid pathway includes an insertion biasing member, a hub, a needle, a retraction biasing member, and a manifold having a septum and a cannula, wherein the annular space between the septum and the cannula defines a 5 manifold header. The manifold and fluid conduit are ventable through the membrane prior to or just after needle and cannula are inserted into the user. Such insertion is caused by the insertion biasing member(s), after which only the needle or another occlusion element is retracted. Such retraction may open a fluid pathway from the manifold header to the body through the cannula and/or needle. A drug delivery pump 10 includes such an insertion mechanism having a vented fluid pathway. The drug delivery pump may contain the insertion mechanism having a vented fluid pathway in either an internally i or an externally tethered configuration. 3238094vl
