Devices, systems, and methods are provided herein for delivering medication (e.g., insulin) via a wearable pump having a patch-style form factor for adhesion to a user's body. The reusable pump may be coupled to a disposable cap housing a microdosing system for delivering precise, repeatable doses of medication to a cannula configured to deliver medication to a target infusion area beneath the user's outer skin layer. The system further may include an applicator for inserting the cannula into the user's skin and/or applying an adhesive pad to the skin.

Drug delivery system, injection device, transfer apparatus, vial holder and method of administering and transferring are disclosed. The system may include transfer apparatus and an injection device. The transfer apparatus may have receiving stations for a drug source, such as a vial or vial holder, and for an injection device, and fluid flow pathways for transferring drugs from the source into the injection device. The injection device may include an expandable elastic bladder and an injection cannula that is movable between a plurality of positions.

The present disclosure relates to a medicament delivery device. The medicament delivery device comprises a housing, a needle and a reservoir. The needle is configured to project from a distal end of the housing. The reservoir is disposed in the housing and has a flexible wall. The medicament delivery device further comprises a dispensing member and a biasing member. The dispensing member is disposed in the housing and the biasing member is configured to bias the dispensing member to move in an arcuate path relative to the housing such that the dispensing member moves across the flexible wall of the reservoir to dispense medicament from the reservoir when the reservoir contains medicament.

A delivery device for administering a drug includes a housing, a reservoir and a drive device with a movable piston rod. The piston rod is guided through an aperture in an inner or outer wall of the housing. The aperture is sealed but allows the piston rod to move. The shape of the circumference of the cross-section of the piston rod is approximately a non-trivial curve of constant width.

A method of dispensing fluid includes three processes. A first one of these processes includes pumping fluid into a resilient variable-volume dispensing chamber. The dispensing chamber is in series with a normally present finite fluid impedance and an output. The impedance is sufficient so as to cause expansion of the dispensing chamber as it receives pumped fluid even while some fluid flows through the output. Another one of these processes includes repeatedly measuring a parameter related to volume of the dispensing chamber over time. A third one of these processes includes controlling the pumping of fluid based on repeated measurements of the parameter to produce a desired fluid flow through the output. A corresponding system for dispensing fluid implements these processes.

A medical device comprising an infusion device comprising a fluid reservoir to contain a therapeutic fluid and a transcutaneous access tool fluidly coupled to the fluid reservoir, the transcutaneous access tool configured to deliver the therapeutic fluid subcutaneously to a patient; wherein the infusion device operates in a stand-by mode prior to the therapeutic fluid being introduced into the fluid reservoir; wherein the infusion device operates to deploy the transcutaneous access tool within a predetermined deployment time period upon filling the fluid reservoir to a predetermined fill level with the therapeutic fluid.

Embodiments of the current disclosure are directed toward systems, devices and methods for diabetes management. In particular, the present disclosure relates to systems, devices and methods for dispensing insulin to a patient using a miniaturized and portable patch pump.

A medication delivery patch that is applied to the skin and activated to deliver a medication or other fluid into or through the skin. The patch may be completely mechanically driven, with no electronic components, for low cost, safety, and reliability. Pressing an activation button may set in motion a sequence of mechanical events that result in a needle exiting the patch into the skin of the user, and flow of fluid from an internal pouch in the patch into the user. When delivery is complete, another sequence of mechanical events may occur to retract the needle from the skin and stop the flow of fluid, and to show a visible indicator that delivery is complete. The patch may contain a fluid channel, such as a microfluidic channel, that controls the rate and time of delivery; this channel can be configured or selected for different medications or use cases.

A drug delivery device includes a housing, a reservoir, a cannula, one or more light sources, a label, and a controller. The reservoir is disposed within the housing. The cannula is connected to the reservoir for delivering a drug from the reservoir to the patient. The light sources are disposed adjacent the exterior surface of the housing, and each serves to indicate one of one or more operational conditions of the device. The label is fixed to the housing adjacent the light sources, and includes one or more informational messages. Each informational message is aligned with one of the light sources for conveniently conveying to a user an operational condition of the device as indicated by the corresponding light source. Finally, the controller is operably connected to the reservoir and the light sources. The controller is configured to actuate the reservoir to deliver the drug, and to selectively illuminate the one or more light sources based on the operational condition of the drug delivery device.

Pads for attaching medicament delivery devices such as autoinjectors to an injection site are presented that include a pad extending along an axis from a proximal end to a distal end, where the proximal end is the end of the pad adjacent to an injection site when the pad is in use, the pad can have an attachment portion configured to receive a medicament delivery device and a second attachment portion attached to the attachment portion, wherein the second attachment portion is arranged at the proximal end of the pad, and wherein the second attachment portion is configured to attach the pad to said injection site when the pad is in use.
