  • Publication number: 20190216397
    Abstract: A medical device includes a hub and an adhesive patch coupled to the hub. The adhesive patch is to couple the hub to an anatomy. The adhesive patch defines an edge that extends along a perimeter of the adhesive patch. The medical device includes an anisotropic shim coupled to the adhesive patch along the perimeter of the adhesive patch proximate the edge to resist an uncoupling of the adhesive patch from the anatomy. The shim has an inner periphery spaced apart from an outer periphery and the shim is locally rigid between the inner periphery and the outer periphery.

  • Publication number: 20190217023
    Abstract: A fluid delivery system and a fluid conduit assembly suitable for use with the system are disclosed herein. The system includes a fluid infusion pump and a fluid conduit assembly coupled to the pump to deliver medication fluid to a user. The fluid conduit assembly includes a structure defining a flow path for the medication fluid, and a gas trapping filter coupled to the structure and positioned in the flow path. The gas trapping filter functions to filter particulates from the medication fluid and retain gas bubbles from the medication fluid.

  • Publication number: 20180200412
    Abstract: This invention pertains to systems and components useful for infusing medications such as insulin. Typically, the components are used to deliver insulin to a diabetic patient at a site of infusion over a period of time greater than 4 days. The system components typically comprise a cannula adapted for subcutaneous insertion into a diabetic patient. The system further comprises a fluid conduit adapted to deliver the insulin solution from a medication reservoir to the site of infusion and a depot in operable contact with the fluid conduit. The depot comprises selected materials including a site-loss mitigating agent (such as heparin) which inhibits inflammation at the site of infusion, and encapsulation of the cannula at the site of infusion. The site-loss mitigating agent is not premixed with the insulin, and instead is adapted to contact the insulin solution in the depot as the insulin solution flows from the medication reservoir to the site of infusion.

  • Publication number: 20170312454
    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.

  • Patent number: 9707336
    Abstract: An infusion system having a priming detection system to indicate that a component of the system, for example a cannula or needle, is primed with a fluid to be delivered into an individual's body. The infusion system utilizes a reactive element that reacts with the fluid or at least one component of the fluid to be delivered, to produce a color change or a colored complex. The reactive element can be deposited, coated or otherwise incorporated in any component of the infusion system that would benefit from a visible indication of a primed fluid, including, but not limited to a tubing, infusion set, cannula, needle and/or guard element at least partially covering or surrounding a cannula or needle. The visual indication improves the user experience during the priming and filling of the system by providing a clear color change confirmation upon priming completion and prior to insertion into the body.

  • Publication number: 20150112302
    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.
