    Abstract: Various embodiments of the present invention are directed to equalizing pressure in a reservoir containing fluidic media, possibly due to imperfect installation of the reservoir or an external influence such as an altitude or a temperature change. In various embodiments, fluidic media may be expelled from the reservoir through a needle and contained in an interior volume of a pierceable member before the needle pierces the pierceable member to establish a flow path to a user. In other embodiments, fluidic media may be expelled through a port of the reservoir into a chamber. In further embodiments, fluidic media may be expelled through a channel in a plunger head and out a passage in the reservoir when the channel and passage are aligned. In other embodiments, fluidic media may be expelled through a valve, and the valve may be pierceable by a needle to establish a flow path to the user.

    Abstract: Various embodiments of the present invention are directed to transferring fluidic media from a vial to a reservoir. In various embodiments, fluidic media may be transferred from the vial to the reservoir by moving a housing portion to move a plunger head located in the reservoir to draw fluidic media from the vial to the reservoir. In other embodiments, fluidic media may be transferred from the vial to the reservoir while the reservoir is held by a holding unit and vibrated by a vibrator to remove air from the fluidic media. In some embodiments, fluidic media may be transferred from the vial to the reservoir by moving a handle operatively connected to a bias member for assisting with the transfer of fluidic media. In other embodiments, the transfer of fluidic media may be assisted by a bias member and a needle connecting atmosphere and the vial.

    Abstract: An infusion set is provided for use in delivering fluid through a cannula, which is housed on a cannula housing, to a selected subcutaneous infusion site on a patient. The fluid is generally a medication, e.g., insulin. The cannula is in fluid communication with a fluid passageway surrounded by a projection on the cannula housing that includes one or more rail-like extensions acting as guides. A connector connects the cannula housing to a fluid delivery system, e.g., an infusion pump. The connector includes a needle, one or more guide arms that slide over the rail-like extensions to guide the needle into the self-sealing septum, and one or more locking arms, with barbs at the end, to connect with corresponding recesses in the cannula housing. An introducer having one or more similar guide arms and locking arms, and a longer needle, may be used to insert the cannula into the patient.
