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 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.
