    • The penetration depth of an intraluminal device, such as a transesophageal probe or a vascular catheter, is monitored by totalizing incremental advancement and withdrawal of the device over time. For a first embodiment, the devices are provided with axially spaced-apart markings along at least a portion of their lengths. The penetration depth of such intraluminal devices into a body lumen is monitored by detecting passage of the markings past a fixed location relative to the body lumen. Usually, the markings will be optically detected in a manner which permits forward and retrograde motion to be distinguished. Thus, the net totalization of the markers will correspond to the actual penetration distance in real time. In an alternate embodiment, the incremental advancement and withdrawal may be followed by use of a contact roller. In either case, the distance can be displayed by itself or in combination with a real time image, with the distance and image optionally being recorded.
    • 管腔内装置如经食管探针或血管导管的穿透深度通过随着时间的推移逐渐增加和撤回装置来监测。 对于第一实施例,装置沿其长度的至少一部分设置有轴向间隔开的标记。 通过检测通过相对于体腔的固定位置的标记的通过来监测这种管腔内装置进入体腔的穿透深度。 通常,将以能够区分向前和逆行运动的方式光学检测标记。 因此,标记的净积分将对应于实时的实际穿透距离。 在替代实施例中,可以使用接触辊来进行增量提前和退出。 在任一种情况下,距离可以自身显示或与实时图像组合显示,距离和图像可选地被记录。
