    • Described herein are imaging catheter system. In an exemplary embodiment, a catheter comprises a handle assembly having distal and proximal ends, a catheter sheath connected to the distal end of the handle assembly, and an elongated flexible tube connected to the proximal end of the handle assembly. The catheter further comprises an imaging core slidably received within the catheter sheath, the handle assembly and the elongated tube. The imaging core also includes a slide member, e.g., knob, extending from the imaging core and passing through an elongated slot in the handle assembly, allowing a physician to manually pullback and advance the imaging core within the catheter by sliding the slide member back and forth. Preferably, the elongated tube is long enough so that the motor drive coupled to the proximal end of the catheter is kept outside the sterile field during the imaging procedure.
    • 这里描述的是成像导管系统。 在示例性实施例中,导管包括具有远端和近端的手柄组件,连接到手柄组件的远端的导管鞘,以及连接到手柄组件的近端的细长柔性管。 该导管还包括可滑动地容纳在导管鞘内的成像芯,手柄组件和细长管。 成像芯还包括从成像芯延伸并穿过手柄组件中的细长狭槽的滑动构件,例如旋钮,允许医师通过滑动滑动构件而手动地将成像芯拉回并推进成像芯, 向前。 优选地,细长管足够长,使得耦合到导管的近端的马达驱动器在成像过程期间保持在无菌区域的外部。
