Abstract: A fluid infusion device includes a housing having a reservoir chamber that receives a fluid reservoir. The fluid reservoir has a first end and a second end. The fluid infusion device includes a connector system having a first body section coupled to a second body section. The first body section defines a bore in communication with a chamber and a counterbore of the second body section to define a fluid flow path. The chamber of the second body section is in fluid communication with a vent subsystem defined through the second body section. The vent subsystem terminates in an outlet, and the vent subsystem is to direct gas in the fluid flow path through the second body section to the outlet. The fluid infusion device includes at least one ring disposed within the reservoir chamber that cooperates with the connector system to securely couple the connector system to the housing.

Abstract: A set connector system for venting a gas from a fluid reservoir of a fluid infusion device is provided. The set connector system includes a connector system having a first body section coupled to a second body section. The first body section defines a bore in communication with a chamber and a counterbore of the second body section to define a fluid flow path from the fluid reservoir. The chamber of the second body section is in fluid communication with a vent subsystem defined through the second body section. The vent subsystem terminates in an outlet, and the vent subsystem directs gas in the fluid flow path through the second body section to the outlet.

Abstract: Methods and devices are provided for reducing a diabetic patient's foreign body immune response, including infusion site-loss and/or occlusion. Such foreign body responses are associated with the treatment of the diabetic patient where the treatment requires subcutaneous implantation of a foreign body, such as a cannula or catheter. In certain embodiments of the invention, a response-inhibiting agent is administered to a patient at the site of cannula/catheter insertion, thereby facilitating delivery of insulin to the diabetic patient and mitigating site-loss and/or occlusion over a period of time.

Abstract: A hub member for an infusion set device includes a body and pads configured to receive a squeezing force directed radially inward relative to an axis of the body. The body compresses radially inward relative to the axis in response to the squeezing force. A plurality of connection features on the body are moveable from a first position radially inward toward a second position when the hub member is compressed radially inward. The connection features engage one or more further connection features on a housing to attach the hub member to the housing when the connection features are in the first position, and disengage the further connection features to release the hub member when the connection features are moved toward the second position.

Abstract: Apparatuses and methods for identifying an infusate in a reservoir of an infusion device and systems for use in filling fluid delivery devices are provided. An exemplary apparatus for identifying an infusate in a reservoir of an infusion device includes a chamber in selective fluid communication with the reservoir. Further, the apparatus includes an indicator located in the chamber. The indicator exhibits a visual change when contacted by an infusate. The apparatus also includes a detector arrangement to identify the infusate by detecting the visual change in the indicator. An exemplary detector arrangement may include a camera to capture an image of the infusate and indicator in the chamber, and an identifier element to compare image data to a library of stored image data.
