Abstract: Apparatus are provided for infusion devices and related control systems and methods. In one embodiment, an infusion device includes a voided portion adapted to receive a shaft portion that includes a shaft coupled to a plunger of a reservoir. The shaft portion includes a detectable feature, and the infusion device includes a sensing arrangement proximate the voided portion to sense the detectable feature. In some embodiments, a control module is coupled to the sensing arrangement to determine a remaining amount of fluid in the reservoir based at least in part on the sensed position of the detectable feature. In other embodiments, the control module identifies an anomalous condition based at least in part on the sensed position of the detectable feature.

Abstract: A method and apparatus for a connection interface between a reservoir or syringe, infusion set tubing, and an infusion pump is provided. The reservoir, a base and a cap are connected to form an integrated unit that is capable of being inserted and secured in an infusion pump housing. The cap and the infusion pump are each provided with at least one sensor or at least one detectable feature, arranged to interact with at least one corresponding detectable feature or sensor on the other of the cap and infusion pump device, to detect one or more of the presence, position or other characteristic of the cap when the cap is aligned or coupled with the infusion pump housing. The detectable feature and sensor may be magnetic, RF, mechanical, optical or any combination.

Abstract: Embodiments relate to a cannula that is provided for delivering a substance, such as a medicine (e.g., insulin) to a patient, where the cannula has reduced likelihood of kinking or occlusions when implanted in a patient. The cannula may have a reduced number of stress concentrations along its length, an angled tip and/or a curve in its length. The cannula may include other designs to reduce kinking, such as internal ribbing and/or a slit along its wall.

Abstract: A device for delivering fluid to a user includes a housing, a drive motor assembly in the housing, a force sensor, and an electronics module. The drive motor assembly regulates delivery of fluid by actuating a piston of a fluid reservoir, and the force sensor generates output levels in response to force imparted thereto during, for example, fluid delivery operations. The electronics module processes the output levels of the force sensor to assess the operating health of the force sensor, to check for occlusions in the fluid delivery path, and to monitor the seating status of the fluid reservoir.

Abstract: A fluid infusion device includes a fluid pump mechanism having a rotor and a stator. The rotor includes an optically detectable feature, a reference surface, and a cam element rising from the reference surface. The stator includes a cam element having a stator cam surface. The cam elements cooperate to axially displace the rotor as a function of angular position of the rotor, wherein the detectable feature rotates and axially translates as a function of angular position of the rotor. A biasing element provides force to urge the rotor cam element toward the stator cam element and toward the reference surface. A drive motor actuates the rotor to pump medication fluid from a fluid cartridge module to a body, via a subcutaneous conduit. An optical detection circuit interrogates the detectable feature during operation of the fluid pump mechanism to determine an operating condition of the fluid pump mechanism.
