  • Patent number: 11931483
    Abstract: Inserts can be formed with elution characteristics to cause the inserts to elute an antimicrobial agent when subject to a fluid within a medical device. An insert can be formed with a desired geometry to allow the insert to be compression fit within a medical device to prevent the insert from moving or becoming dislodged once inserted into the medical device. The material may also be hygroscopic so that the insert swells when subject to a fluid thereby enhancing the compression fit of the device within the medical device. In some cases, the material can be reinforced using an internal structure. Inserts can be formed in many ways including by casting, thermoforming, or extrusion. In some cases, the inserts can be formed using a peel-away sleeve or material. The peel-away sleeves can be formed of a non-sticky material which facilitates removal of the inserts once the inserts have cured.

  • Publication number: 20230364407
    Abstract: A cap is configured to provide antimicrobial protection to a female luer port of an intravenous device. The cap distributes an antimicrobial solution within the intraluminal surfaces of the port when the cap is connected to the port. A cap may also be designed to distribute an antimicrobial solution around the exterior surfaces of the port. Once connected to a port, the cap can form a seal that minimizes the evaporation of the antimicrobial solution from within the lumen of a port. The cap can therefore provide antimicrobial protection against another device that is connected to the port once the cap is removed.
