    Abstract: Apparatuses, systems and methods for the wireless communication of medical devices in a subcutaneous fluid delivery system are disclosed. A system for subcutaneous fluid delivery includes a primary patch pump adapted to attach a first infusion cannula to a user and to perform a plurality of primary patch pump functions, and a secondary patch pump adapted to attach a second infusion cannula to a user. The secondary patch pump is further adapted to perform a plurality of secondary patch pump functions substantially similar to the plurality of primary patch pump functions if an error condition associated with the primary patch pump is determined.

    Abstract: A needle assembly includes a needle and a needle shield device. The needle shield device includes an inner shield connectable to at least one a base and a fluid connector connectable to the base, and an outer shield fixedly connected to the opposing end the needle and displaceable relative to the inner shield between a first position, in which the sharpened end of the needle is exposed outside the inner shield, and a second position, in which the sharpened end of the needle is shielded by the inner shield. Interaction between portions of the inner and outer shields during or after proximal displacement of the outer shield from the first position to the second position automatically releases or permits release of the inner shield from connection to the at least one of the base and the fluid connector.

    Abstract: Provided is a wearable, self-contained drug infusion or medical device capable of communicating with a host controller or other external devices via a personal area network (PAN). The medical device utilizes a PAN transceiver for communication with other devices in contact with a user's body, such as a physiological sensor or host controller, by propagating a current across the user's body via capacitive coupling. The wearable nature of the medical device and the low power requirements of the PAN communication system enable the medical device to utilize alternative energy harvesting techniques for powering the device. The medical device preferably utilizes thermal, kinetic and other energy harvesting techniques for capturing energy from the user and the environment during normal use of the medical device. A system power distribution unit is provided for managing the harvested energy and selectively supplying power to the medical device during system operation.
