摘要： A catheter adapter may include a distal end, a proximal end, an inner surface extending through the distal end and the proximal end and forming a lumen, and a side port forming a side port pathway through a sidewall of the catheter adapter and in fluid communication with the lumen. The catheter assembly may include a catheter extending distally from the distal end of the catheter adapter. The catheter assembly may include a septum disposed within the lumen proximal to the side port pathway. The catheter assembly may include one or more features to facilitate flushing of the catheter assembly: a diameter of the side port may increase in a distal direction; a portion of the inner surface proximal to the catheter and distal to the septum may include multiple grooves; the side port pathway may include a non-cylindrical portion; an insert; a rotation element; and a pivot element.

摘要： An instrument advancement device may include a housing, which may include a slot. The instrument advancement device may be configured to couple to a catheter assembly. The instrument advancement device may include an advancement element, which may extend through the slot and may be configured to move linearly along the slot between a retracted position and an advanced position. In response to movement of the advancement element from a retracted position to an advanced position, an instrument of the instrument advancement device may be advanced beyond a distal end of the housing and may be configured to open a path through an occlusion in the catheter assembly or vasculature. The instrument advancement device may include a septum, which may be engaged to facilitate sealing of the housing and/or prevent buckling of the instrument.

摘要： A needleless luer access connector is disclosed having a septum disposed in a housing. The septum has a proximal portion with a cross section, a medial portion with a cross section smaller than the cross section of the proximal portion, and a distal portion. A longitudinal slit extends through the septum from the proximal portion to the distal portion. The septum and housing are designed so that septum will not be rotated or removed from the housing when the connector is accessed by a male luer taper. In addition, the septum and housing are designed to bias the slit at the distal portion closed and so a male luer connector does not have to extend completely through the distal portion to open the slit at the distal portion. Finally, the septum and housing are designed to minimize the amount of dead space in the connector when accessed with a male luer taper.

摘要： 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.

摘要： A catheter adapter including a housing and an extension portion extending from the distal end of the housing and defining a passageway configured to receive a catheter. The first material of the housing is more flexible than the second material of the extension portion. The catheter adapter may further include a body contact portion comprising an upper surface corresponding to a surface of the housing and a lower surface defining an outer surface of the catheter adapter. The housing may include a body, an access port extending from the body, and a plurality of protrusions extending from the body and/or the access port. The body contact portion covers at least a portion of the housing, and the protrusions are embedded in and are completely surrounded by the body contact portion. The catheter adapter may further include a connection portion connecting the extension portion to the body contact portion.
