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 a flexible body that allows the clearing tool to deflect when entering the epidural space through a window in the vertebral bone and ligaments. The clearing tool is guided into the epidural space and to a target site by a guidewire present in the epidural space. Upon removal of the guidewire and clearing tool, the medical lead is inserted through the window and cleared epidural space until reaching the target site. The clearing tool may include a distal tip with a shape and size that aids in the clearing of the epidural space. The distal tip may be integral to the clearing tool or may be removable so as to allow for different sizes of the distal tip to be installed as needed.

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 multiple links that allow the creation of a deflection angle. A wire passes through the links and once the links are positioned with the desired deflection angle, tension is placed on the wire to lock the links into the current position. The clearing tool is inserted through a window into the epidural space, and once the tension is applied to the wire, the clearing tool becomes rigid to allow advancement of the clearing tool within the epidural space. The clearing tool is then removed from the epidural space, and the medical lead is inserted through the window and cleared epidural space until reaching the target site.

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.
