    • A catheter assembly (10) having an outer catheter (12) and an inner catheter (14) extending coaxially through the outer catheter, and a hub (16). The inner catheter (14) is axially movable within and with respect to the outer catheter (14) by use of an actuator assembly (130) such that the catheter assembly has an opened condition permitting fluid communication with vasculature of a patient, and a closed condition preventing fluid communication with the vasculature of the patient. The opened condition permits the intended use of the catheter assembly such as for hemodialysis of the patient. In the closed condition, locking solution may be maintained in the catheter assembly and later removed therefrom, with essentially no locking solution leaving the catheter assembly or entering the patient. The actuator assembly (130) is secured to a proximal end portion (128) of the inner catheter (14) as it protrudes proximally from the hub (16), where it is accessible to the practitioner. The actuator assembly (130) may comprise an adapter sleeve (90) fixed to the inner catheter (14), and a swivel sleeve (92) which is rotatable with respect to both the adapter sleeve (90) and the hub (16).
    • 具有外导管(12)和同轴地穿过外导管延伸的内导管(14)的导管组件(10)和毂(16)。 内导管(14)通过使用致动器组件(130)在内导管(14)内并相对于外导管(14)轴向移动,使得导管组件具有允许与患者脉管系统流体连通的打开状态,并且闭合 防止与患者脉管系统的流体连通。 打开的状态允许导管组件的预期用途,例如用于患者的血液透析。 在关闭状态下,锁定溶液可以保持在导管组件中并随后从其中移除,基本上没有离开导管组件或进入患者的锁定溶液。 致动器组件(130)当其从轮毂(16)向近侧突出时被固定到内部导管(14)的近端部分(128),在那里它可以由从业者接近。 致动器组件(130)可以包括固定到内部导管(14)的适配器套筒(90)和可相对于适配套筒(90)和轮毂(16)旋转的旋转套筒(92)。
