A wearable injector for automated delivery of biologic drugs that solves the problem of high volume and high viscosity drug administration by providing a device that can be worn by the patient through use of an adhesive patch to deliver the medication slowly over extended periods of time.

Embodiments of the current disclosure are directed toward systems, devices and methods for diabetes management. In particular, the present disclosure relates to devices and methods for dispensing insulin to a patient. A portable fluid infusion device, comprising a disposable part (DP) and a reusable part (RP) is disclosed. The DP comprises a first reservoir and a second reservoir, the second reservoir less than or equal to the first reservoir in length, while the RP comprises a first compartment configured to receive the first reservoir, a second compartment configured to receive the second reservoir and a gasket for sealing a junction between the second reservoir and the second compartment upon connection of the RP and the DP.

A catheter priming apparatus may include a barrier forming a reservoir. Fluid may be disposed within the reservoir. A support structure may be disposed within the barrier. The support structure may include an opening extending through the support structure and a connector configured to couple the catheter priming apparatus to a catheter system. A one-way valve may be coupled to the support structure and configured to allow the fluid to flow out of the reservoir through the connector in response to compression of a portion of the barrier aligned with the opening.

Delivery systems and methods for forming and delivering biomaterials from two components are described herein. In particular, apparatus and methods for performing controlled delivery of multicomponent delivery of biomaterials into or onto a body part, such as a body lumen are described. More specifically, in some embodiments, the apparatus and methods are directed towards controlled delivery of micro-volumes of biomaterials into or onto a target location, the micro-volumes being defined as 0.001 mL-1 mL (or 1 μL-1,000 μL) of volume.

A repeater system may control a pump by using a repeater and a user interface. An adhesive patch system may be used for affixing a pump or other object to a human body. Such an adhesive patch system may include two sets of adhesive members, each member including an adhesive material on at least one side so as to attach to the body. The members of the first set are spaced to allow the members of the second set to attach to the body in spaces provided between the members of the first set, and the members of the second set are spaced to allow members of the first set to detach from the body without detaching the members of the second set. Also, fill stations and base stations are provided for personal pump systems.

A priming assembly for a drug delivery device includes a hub, a base connected to the hub and moveable relative to the hub between a first position and a second position, with the base defining a passageway, a cap defining an interior chamber and a passageway in fluid communication with the interior chamber, and a needle connected to the hub and positioned within the interior chamber of the cap, where the passageway of the base is in fluid communication with the passageway of the cap when the base is in the first position, and where the passageway of the base is isolated from the passageway of the cap when the base is in the second position.

A device for delivering a medical fluid (4) comprising a body which houses: at least one containment tank (20) of a medical fluid, a fluid injection device (24) which interfaces with said containment tank (20) and is suitable to allow controlled delivery of a fluid through a cannula (32), an extraction device (40) of the cannula (32) from a retracted or rest configuration to an extracted or infusion configuration, activation means (44) which comprise a rotor (48), rotatable about a rotation axis (X-X) in an injection rotation direction (I) and in a control rotation direction (C), opposite each other.

An air filter device for medicinal liquid injection in which a medicinal liquid channel is formed includes: a housing having an air passage that diverges from the medicinal liquid channel and is connected to outside; a hydrophilic boundary filter disposed in the medicinal liquid channel and dividing the medicinal liquid channel into a first channel at an upstream side and a second channel at a downstream side; and a hydrophobic air-passing filter disposed at a boundary between the air passage and the first channel.

A suspension of a therapeutic substance (e.g., embolic beads) dispersed within a liquid can be delivered via a catheter by using a bidirectional pump to rapidly draw the mixture of the therapeutic substance and liquid from an external syringe into an internal reservoir, then rapidly push the mixture back out into the external syringe. The rapid operation of the bidirectional pump mixes the two constituents so that the therapeutic substance is temporarily suspended within the liquid. Then, a low-speed pump is used to inject the mixture out via the catheter. In some embodiments, the parameters of the low-speed pump are controlled so that the fluid exiting the catheter will experience laminar flow. When the therapeutic substance comprises embolic beads, this can advantageously prevent reflux of the embolic beads, which can be dangerous.

A controller controls a fluid pump to deliver primary fluid from a first source at a desired rate through a respective conduit to a recipient. The controller monitors a volume of the primary fluid injected into the conduit. Subsequent to injecting a predetermined amount of the primary fluid into the conduit, the controller i) discontinues injection of the primary fluid into the conduit and ii) injects a secondary fluid through the conduit to advance a remaining portion of the primary fluid in the conduit to the recipient. The controller advances the secondary fluid into the conduit until a desired amount of the primary fluid is delivered trough the conduit to the recipient. Injection of the secondary fluid to push the remaining portion of the primary fluid reduces waste associated with the primary fluid.
