Abstract: The present invention provides an improved cannula (22) that can be used to reconstitute powdered drugs in a drug delivery system. Furthermore, the present invention provides a cannula (22) and drug delivery system incorporating same. To this end, the present invention provides a cannula structure for use in a reconstitution of a powdered drug comprising a cannula (22) having a first end (26) and a second end (28), and defining a channel in an interior thereof between the first and second ends (26, 28). The first end (26) is closed and includes a member (27) for piercing a septum (42). The cannula (22) includes at least two slots (50a, 50b) providing fluid communication between the channel and an exterior of the cannula (22). The slots (50a, 50b) are located in juxtaposition to the first end (26) and have a width, as measured along a length of the cannula (22), that is less than a length, as measured around the cannula (22). The slots (50a, 50b) also have a minimum projected area equal to or greater than the cross-sectional area of the channel.

Abstract: The present invention provides a system for automatically rec- onstituting a drug in-line and delivering the drug to a patient. Pursu- ant to the present invention, a system is provided that allows fluid en- try into a vial, that houses the drug to be reconstituted, with concur- rent air elimination. Mixing via different fluid entry levels is pro- vided. Due to the unique fluid flow path of the present invention reconstitution of the drug is ensured. The system, method, and appar- atus of the present invention can be utilized with a computer con- trolled pump. When so utilized, a completely automated procedure can be achieved.
