Abstract: A fluid delivery device comprising a fluid reservoir; a transcutaneous access tool fluidly coupled to the fluid reservoir, the transcutaneous access tool including a needle or a trocar; and a transcutaneous access tool insertion mechanism for deploying the transcutaneous access tool, wherein the insertion mechanism is configured to insert and retract the needle/trocar in a single, uninterrupted motion.

Abstract: An infusion device comprising a fluid reservoir for containing a therapeutic fluid; and a transcutaneous access tool fluidly coupled to the fluid reservoir for delivering the therapeutic fluid subcutaneously and for introducing a monitoring test strip subcutaneously, and methods of use thereof.

Abstract: A fluid delivery device comprising a fluid reservoir; a transcutaneous access tool fluidly coupled to the fluid reservoir; and a drive mechanism for driving fluid from the reservoir, the drive mechanism comprising a plunger received in the reservoir; a leadscrew extending from the plunger; a nut threadably engaged with the leadscrew; a drive wheel; and a clutch mechanism coupled to the drive wheel, wherein the clutch mechanism is configured to allow the nut to pass through when disengaged and is configured to grip the nut when engaged such that the drive wheel rotates the nut to advance the drive rod and the plunger into the reservoir.

Abstract: A physiological parameter associated with tissue of a host may be monitored in the tissue to confirm subcutaneous delivery of medication to the host. More particularly, such may involve delivering medication subcutaneously to the host with a medical device which includes a sensor used to measure the physiological parameter, particularly within a predetermined time period after delivery of the medication. Such may also or otherwise involve forming a depot in the tissue with the medication, and using the sensor to measure the physiological parameter while the sensor is at least partially within the depot.

Abstract: A system and method may be used to calculate insulin on board (IOB) for an extended bolus being delivered by an insulin infusion pump. In general, the system and method calculates an extended bolus IOB value for the extended bolus, which takes into account the insulin currently on board from the extended bolus and the insulin scheduled to be delivered by the extended bolus over a subsequent time period equivalent to a duration of insulin action. The extended bolus IOB value may be used to calculate a suggested bolus.

Abstract: A prefilled syringe may be interfaced with and used to fill an infusion pump with therapeutic liquid. The dispensing end of the prefilled syringe may be coupled (either directly or indirectly using a syringe cap) to a syringe coupling region of the infusion pump, for example, using a threaded engagement or snap fit engagement. As the dispensing end of the prefilled syringe is coupled to the syringe coupling region of the pump housing, a needle passes through the pump housing and/or a needle passage region of the dispensing end such that the prefilled syringe is fluidly coupled to a reservoir in the pump. In various embodiments, the needle may be located in the syringe coupling region or in a syringe cap coupled to the dispensing end of the prefilled syringe.

Abstract: A device for delivering fluid to a patient including an exit port assembly adapted to connect to a transcutaneous patient access tool, a flow path extending from the exit port assembly, and a flow condition sensor assembly including a resilient diaphragm having opposing first and second surfaces. The first surface of the diaphragm is positioned against the flow path, and a chamber wall is positioned adjacent the second surface of the diaphragm and defines a sensor chamber against the second surface of the diaphragm. At least one sensor is arranged to provide a threshold signal when the second surface of the diaphragm expands into the chamber in response to at least one predetermined fluid flow condition occurring in the flow path.

Abstract: An environmental seal for a fluid delivery device may include a 2-shot molded cap including a carrier and a low durometer silicone plug. The seal also may include a cap receptacle that applies compressive force to the plug displacing the plug material and forming a seal between the cap, the plug and the cap receptacle. A cannula may be slidably received in the plug and may move freely through the plug without compromising the seal.

Abstract: An interactive training system and method may interactively train or instruct a user on how to use a device, such as a hand-held drug delivery management device. The interactive training system and method may provide one or more interactive tutorials on various aspects or features of the device by displaying a virtual representation of the device and by allowing a user to interact with the virtual representation of the device to simulate use of the device. An interactive tutorial may provide one or more interaction prompts prompting a user to perform one or more steps simulating interaction with the device by activating user controls on the virtual representation and may simulate a response on the virtual representation in response to user activation of the user controls.
