Abstract: An epidural space is cleared of fat and scar tissue in preparation for implantation of a medical lead by utilizing a clearing tool. The clearing tool has an outer body and an inner body present within a lumen of the outer body. The outer body may be malleable and have a pre-set deflection or may be flexible and achieve deflection when being inserted into the epidural space. Once in the epidural space, the inner body is extended distally from the lumen of the outer body such that a distal tip on the inner body extends further into the epidural space to provide clearing to the target site without requiring further ingress of the outer body. The inner body is retracted and the clearing tool is removed. The medical lead is then inserted through the window and cleared epidural space until reaching the target site.

Abstract translation: 通过利用清除工具，可以将硬膜外腔清除脂肪和瘢痕组织，以准备植入医用铅。 清除工具具有外体和存在于外体的内腔内的内体。 外体可以是可延展的并且具有预设的偏转或者可以是柔性的，并且当插入硬膜外腔时实现偏转。 一旦在硬膜外腔中，内体从外体的内腔向远端延伸，使得内体上的远侧末端进一步延伸进入硬膜外腔，以便在不需要进一步进入外体的情况下向目标部位提供清除。 内体缩回，并清除清理工具。 然后将医疗用铅插入窗户并清除硬膜外腔，直到达到目标部位。
