摘要：
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.
