  • Patent number: 12364421
    Abstract: An IV catheter device can include or being configured to employ a probe assembly having an integrated fluid flushing mechanism. The probe assembly can be configured in a variety of ways to cause flushing fluid to be injected through a fluid permeable structure of the probe as the probe is advanced distally from a catheter. In this way, the fluid permeable structure can be kept clear of any occlusion that may otherwise form. With the probe extending distally from the catheter, a blood sample may be collected.

  • Patent number: 12311081
    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.

  • Patent number: 12280232
    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.

  • Patent number: 12171970
    Abstract: A vascular access device including a catheter adapter, a port opening, and an elastomeric valve. The catheter adapter extends along a longitudinal axis and includes a proximal end, a distal end, and a lumen extending therebetween. The port opening is formed in a surface of the catheter adapter in fluid communication with a side port of the catheter adapter and the lumen. A structural geometry of the port opening directs a fluid into the lumen in a proximal direction. The elastomeric port valve is disposed within the lumen and configured to deform in response to a transverse force applied thereto. A proximal gap may result between the inner wall forming the lumen and a proximal side of the elastomeric port valve, thereby opening a fluid path.
