Abstract
A method of epidural surgery is provided that improves visibility in the epidural space of a patient for more effectively conducting therapeutic surgery therein. The method includes the steps of distending a portion of the epidural space of a patient by filling the portion of the epidural space with a fluid supplied from a catheter and positioning a portion of an optical scope in the distended portion of the epidural space by inserting the optical scope through the same catheter that supplies the distending fluid to thereby provide a visual image of the epidural space.
Claims
That which is claimed is:
1. A method of epidural surgery comprising the steps of:
distending a portion of the epidural space of a patient by providing the portion of the epidural space with a fluid supplied from a catheter positioned in the epidural space to thereby improve visual imaging of the epidural space.
2. A method of epidural surgery according to claim 1, further comprising the step of performing a therapeutic treatment on a problem area within the distended portion of the epidural space.
Description
FIELD OF THE INVENTION
This invention relates to surgical methods, and more particularly to methods of epidural surgery in and around the epidural space.
BACKGROUND OF THE INVENTION
Back pain, and particularly lower back pain, is a major expense to society and is one of the most common disabling problems of those of working age. Injuries to the back vary from herniated disks of the spine to muscle strains and nerve damage. In the back or posterior end of the human body, the epidural space is potential space located in and extending the length of the spine. The epidural space is defined along one edge or side by the dura mater which surrounds the spinal cord. The epidural space is further defined along a second edge or side by the periosteum of the bony vertebrae or by the ligamentum-flavum at the vertebr |
