  • Publication number: 20250032757
    Abstract: An instrument delivery device to insert an instrument through a catheter assembly may include a housing, a connector coupled to the housing, a slider configured to move along a slot of the housing, and an instrument disposed within the housing and coupled to the slider. The instrument may be configured to advance beyond the connector in response to movement of the slider along the slot from a proximal position to a distal position. The connector may include a curved portion configured to change a direction of the instrument when the instrument is advanced through the connector. A catheter system may include a catheter adapter, which may include a side port. An annular valve may be disposed within the lumen and configured to seal the side port. The catheter system may include an instrument advancement feature configured to direct the instrument in a distal direction within the lumen of the catheter adapter.

  • Publication number: 20250025669
    Abstract: A catheter assembly may include a catheter, catheter adapter, needle, needle guard, and housing. The housing may be coupled to the needle guard and disposed within a lumen of the catheter adapter. The needle guard may include first and second resilient arms, which may include first and second curved portions, respectively. When the needle is in a ready position, the first and second curved portions may be urged by a shaft of the needle into retaining contact with an inner wall of the catheter adapter. When the needle is in the retracted position, the shaft may no longer bias the first and second resilient arms outwardly such that the retaining contact between the first and second curved portions and the catheter adapter is released, and the housing and the needle guard enclose a distal tip of the needle.

  • Patent number: 12194249
    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: 20250000405
    Abstract: Ported catheters can be configured to facilitate insertion of a blood draw device or other vascular probe or instrument. A ported catheter may include a bushing, or wedge, that is shaped to provide a smooth entry and advancement of a tube of a blood draw device that is coupled to the ported catheter, whether via a proximal opening or a port of the ported catheter. Such a bushing may be particularly beneficial when the port of the ported catheter is oriented at an angle towards the catheter. By incorporating such a bushing, a ported catheter may be better able to minimize the occurrence of kinking or bending of the tube of the blood draw device. A ported catheter may also include a catheter strain relief feature to minimize the occurrence of kinking or bending of the tube of the blood draw device while it is extended through the catheter.

  • Patent number: 12161834
    Abstract: A device to couple a vascular access device to a medical device may include a body, a spring, and a housing. The body may include a distal end, a proximal end, and a lumen extending through the distal end and the proximal end. The proximal end of the body may include a connector. The housing may be coupled to a proximal end of the spring and may enclose the connector. A distal end of the spring may be coupled to the body. The housing may include a flap, which may include an antimicrobial compound. When the housing is disposed in a proximal position, the flap may cover the connector, the antimicrobial compound may contact the connector, and the spring may be uncompressed. In response to movement of the housing from the proximal position to a distal position, the spring may be compressed and the flap may open.

  • Patent number: 12005204
    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.

  • Patent number: 11998719
    Abstract: A sealed fluid transfer device comprised of tubing, a proximal fitting, and a distal needle assembly is provided. The needle assembly includes a needle hub secured to a needle cannula. A cantilevered actuator arm extends outwardly from the needle hub having an actuator button at its free end. The needle assembly is disposed in a barrel and can move from a distal position, where the needle is exposed, to a proximal position, where the needle is shielded. The barrel includes a septum which seals the barrel. A spring is disposed in the barrel for propelling the needle assembly to the proximal position. The barrel includes an aperture that receives the actuator button for locking the spring in a compressed condition. Depression of the actuator button enables the spring to propel the needle assembly into its proximal position. A safety mechanism prevents inadvertent depression of the actuator button.
