  • Patent number: 11534581
    Abstract: An extravascular system is provided which includes a catheter adapter having a blood control septum configured to control flow of a fluid through the catheter adapter, the catheter adapter further having a catheter configured for intravenous insertion. The extravascular system further includes a septum activator slidably inserted within the catheter adapter and configured for advancement through the blood control septum to provide a fluid pathway through the blood control septum. Further still, the extravascular system includes an external safety mechanism comprising a needle hub and a needle shield interconnected via a tether, wherein the needle shield includes a safety clip that is configured to retain a sharpened end of the introducer needle within the needle shield. Some implementations further comprise an access port forming a portion of the catheter adapter and providing selective access to the lumen of the catheter adapter.

    Abstract: A vein simulator system can be used by clinicians to improve their proficiency in placing catheters such as PIVCs or in otherwise accessing a vasculature. A vein simulator system can include a simulated portion of a body, such as a simulated human arm, that includes at least one simulated vein. The vein simulator system can also include a control system, one or more sensors and one or more feedback components.

  • Patent number: 11497848
    Abstract: A system to detect occlusion of an intravenous catheter may include a housing, which may include a distal end configured to couple to a proximal end of a catheter adapter and an inner lumen forming a fluid pathway. The system may also include a wave transmitter, a transducer disposed within the fluid pathway, a processor coupled to the transducer, and an indicator unit coupled to the processor. The wave transmitter may transmit energy waves along a length of an intravenous catheter of the catheter adapter. The processor may receive an electrical signal corresponding to the portion of the energy waves that are reflected back from the intravenous catheter and may determine a difference between the electrical signal and a baseline signal. In response to the difference between the electrical signal and the baseline signal meeting a threshold value, the indicator unit may alert a user.

    Abstract: Disclosed herein are magnetically trackable stylets and methods thereof. A magnetically trackable stylet can include a stylet body including a core wire, a magnetic assembly, and an outer construction over the core wire and the magnetic assembly. The magnetic assembly can include one or more magnetic field-producing elements disposed alongside the core wire in a magnetically trackable distal portion of the stylet body. The outer construction, which can be an overmolded layer, a reflowed layer, a potting layer, or a shrink-wrapped layer, can be around the core wire and the magnetic assembly. The stylet body can be configured to be disposed in a lumen of a medical device such as a catheter for magnetically tracking a tip of the medical device in vivo without breakage of the stylet body due to bending-related fatigue. A method of such a magnetically trackable stylet can include a method of using the stylet.

  • Patent number: 11478610
    Abstract: The present invention relates to a multiple-use intravenous (IV) catheter assembly septum and septum actuator. In particular, the present invention relates to an IV catheter assembly having a stationary septum actuator and a blood control septum, wherein the blood control septum is configured to slide within a catheter adapter of the IV catheter assembly between a compressed state and an uncompressed state. When in the compressed state, a slit of the blood control septum is opened and the septum comprises stored compressive potential energy. When the septum is released from the compressed state, the stored compressive potential energy is release and the blood control septum is restored to its original shape, thereby closing the septum's slit.

  • Publication number: 20220257909
    Abstract: A catheter system may include a needle assembly coupled to a catheter adapter. The needle assembly may include a housing, an introducer needle, a proximal opening, a distal opening, and a needle tip shield feature. A distal tip of the introducer needle may be configured to be proximally withdrawn from a first position to a second position in which a bump feature of the introducer needle contacts and is prevented from moving through the proximal opening. In response to withdrawal of the distal tip proximally from the second position to a third position, the housing may move proximally, and the needle tip shield feature may be released to block the distal opening. The needle tip shield feature may not contact the introducer needle when the distal tip moves proximally from the first position to the second position and from the second position to the third position, which may reduce a friction-based drag force on the introducer needle.

  • Patent number: 11383074
    Abstract: A system to detect occlusion of an intravenous catheter may include a housing, which may include a distal end configured to couple to a proximal end of a catheter adapter and an inner lumen forming a fluid pathway. The system may also include one or more transmitters, which may be disposed within the housing. The transmitters may be configured to transmit first energy waves along a length of an intravenous catheter at a first frequency, and a portion of the first energy waves that are reflected back from the catheter may be detected by the system. Based on the portion of the first energy waves that are reflected back from the catheter, the transmitters may transmit second energy waves along the length of the catheter at a second frequency, which may be greater than the first frequency and configured to reduce formation of blood clots within the catheter.
