ABSTRACT:
A novel subcutaneous tunneling device is disclosed which is particularly directed to long-term epidural catheters for relieving intractable pain, which catheters require tunneling from the paravertebral incision where the catheter is introduced into the epidural space to a lateral location where administration of a narcotic is more conveniently handled. The tunneling device consists essentially of a hollow shaft having a solid removable cutting tip on one end thereof. Following removal of the solid cutting tip, a catheter, cannula or other tubular article may then be passed through the shaft.
