  • Publication number: 20200164159
    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.

  • Publication number: 20200138852
    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.

  • Patent number: 9265890
    Abstract: Syringe pistons for a fluid syringe, and related sealing elements, are presented here. A syringe piston includes a piston body having a fluid end, an actuator end, and an outer seal-retaining surface between the fluid end and the actuator end. The syringe piston may utilize a piston sealing sleeve or a piston sealing cover. The sleeve can be coupled to the piston body around the outer seal-retaining surface, the piston sealing sleeve having a fin-shaped fluid seal element to form an interference fluid seal with an interior wall of a syringe barrel. The sealing cover can be coupled overlying the tip of the piston body. The cover has a fin-shaped fluid seal element to form an interference fluid seal with an interior wall of a syringe barrel.

  • Patent number: 9199043
    Abstract: A fluid syringe of the type used with fluid infusion devices is presented here. The fluid syringe generally includes a barrel, a piston, and a check valve seal. The barrel has an interior wall and a sealed main fluid chamber. The piston is slidably coupled within the barrel, and the piston has a piston seal forming an interference fluid seal against the interior wall. The check valve seal is coupled to the piston, and it is located between the piston seal and the main fluid chamber. The check valve seal forms an interference fluid seal against the interior wall when the piston is unloaded, and it disengages the interior wall to allow gas flow from the main fluid chamber toward the piston seal when the piston is loaded.
