Abstract: A device in accordance with an embodiment of the present technology includes a port through which the device receives and dispenses infusion liquid (e.g., insulin solution) and a container that holds the infusion liquid. The device also includes a hub at a flowpath extending between the port and the container. The hub defines a first passage and a second passage in parallel with one another. The device further includes a conditioner and a check valve at the first and second passages, respectively. The conditioner conditions liquid moving between the container and the port by passing the liquid through an adsorbent filter and a mechanical filter. The check valve causes liquid moving between the port and the container to move preferentially via the first passage when flowing in one direction and to move preferentially via the second passage when flowing in an opposite direction.

Abstract: Disclosed herein are techniques related to insertion of a fluid conduit (e.g., tubing connected to a fluid reservoir or a cannula sharing a pre-assembled fluid pathway with such tubing). In some embodiments, an insertion mechanism may include one or more springs (e.g., a torsion spring or a compression spring). The one or more springs may cause a trocar or a trocar slider to pierce tissue and insert the fluid conduit. The one or more springs may further cause the trocar or the trocar slider to be removed from the tissue.

Abstract: According to an aspect, a cannula insertion mechanism includes a seal and a cannula carrier. The seal is configured to surround an opening of a housing, the seal including a first seal surface and a second seal surface, the first seal surface facing toward the opening, and the second seal surface facing away from the opening. The cannula carrier is configured to drive a cannula in a first direction through the opening of the housing, the cannula carrier having a first carrier surface and a second carrier surface, the first carrier surface being configured to exert a compression force on the second seal surface when the cannula carrier drives the cannula in the first direction, thereby causing the first seal surface to expand in a second direction to engage the second carrier surface via a clamping force.

Abstract: Disclosed herein are different disposable assemblies for the same reusable assembly. The different disposable assemblies include a first disposable assembly and a second disposable assembly. The first disposable assembly may be configured to be operatively coupled to the reusable assembly to deliver fluid, and the second disposable assembly may be configured to be operatively coupled to the reusable assembly to deliver fluid when the first disposable assembly is not operatively coupled to the reusable assembly. The first disposable assembly may have a first set of one or more characteristics, and the second disposable assembly may have a second set of one or more characteristics that is different from the first set of one or more characteristics.

Abstract: In some embodiments, an infusion device can include a reservoir configured to hold a medicament, a first epicyclic gear arrangement comprising a first output, a second epicyclic gear arrangement comprising a second output, a first trocar coupled to the first output and movably coupled to a sensor electrode, and a second trocar coupled to the second output and movably coupled to an infusion cannula that is fluidically coupled to the reservoir. Actuation of the first epicyclic gear arrangement can drive linear travel of the first trocar and/or the sensor electrode, and actuation of the second epicyclic gear arrangement can drive linear travel of the second trocar and/or the infusion cannula.

Abstract: Systems and methods for driving electrical motors of medicament infusion pumps are disclosed. An infusion device for delivering a medicament to a body of a user can include a reservoir to contain medicament, a dispenser to cause medicament to be moved out of the reservoir, and a motor operably coupled to the dispenser. The motor can include a stator defining a central opening and a rotor removably disposed therein. A controller coupled to the stator is configured to (1) supply a first signal to the stator to cause the rotor to rotate in a first direction for a first rotational amount less than a full rotation; and (2) to then supply a second signal to the stator to cause the rotor to rotate in a second, opposite direction for a second rotational amount greater than the first, thereby causing medicament to be dispensed from the reservoir via the dispenser.

Abstract: A hydraulically actuated valve device includes a valve body having an inner cavity, an inlet channel extending to the inner cavity, an outlet channel extending from the inner cavity, and an open end that opens to the inner cavity. A septum is located in the inner cavity to seal the open end of the valve body and to receive a needle through which an operating fluid may be selectively injected into or withdrawn from the inner cavity to increase or reduce a fluid pressure in the inner cavity. A valve closing member has an unactuated state to enable a first fluid to flow from the inlet channel to the outlet channel when the fluid pressure of operating fluid in the inner cavity of the valve body is below a closing pressure, and inhibits the first fluid from flowing out of the inner cavity through the outlet channel when the operating fluid in the inner cavity of the valve body is at or above the closing pressure.
