Problems solved by technology
These anatomical components make it difficult to treat or diagnose conditions within the epidural area as they tend to curl around any instrument or device inserted therein
This may impair visibility within the epidural space and may cause inadvertent damage to the nerve root during device insertion
In addition, insertion of a viewing device may result in blocking or diminished viewing ability
As such, many anatomical components within the epidural space can limit the insertion, movement, and visualization capabilities of any access, visualization, diagnostic, or therapeutic device inserted into the epidural space

Abstract
Balloon cannula systems may be used for accessing and visualizing the spine and related methods of treatment, including a forward-looking balloon system for creating a working space and the balloon system having atraumatic dissection capability to allow visualization in spine. The devices and methods described may be used, for example, to perform annulus repair, herniated disc excision, and denervation of neurological tissue; to dispense pharmacological agents and / or cell or tissue therapy agents; to diagnose disc degeneration and bony degeneration, spinal stenosis, and nucleus decompression, and to perform disc augmentation.

Cross References to Related Applications This application claims U.S. Provisional Application Serial No. 60 / 968,086 filed August 27, 2007 and U.S. Provisional Application Serial No. 61 / 045,919 filed April 17, 2008 under 35 U.S.C. § 119(e) Priority, all of which are hereby incorporated by reference in their entirety. Background technique Damaged discs are often treated with bed rest, physical therapy, restorative activities, and pain medication for long-term treatment. There are also a variety of treatment modalities that attempt to repair damaged discs and avoid surgical removal of damaged discs. For example, disc decompression is a surgical procedure used to remove or shrink the nucleus pulposus, thereby reducing pressure on the annulus and nerves. Less invasive surgical methods, such as minimally invasive lumbar discectomy and automated percutaneous lumbar discectomy, remove the nucleus pulposus of the disc by aspiration through a needle inserted transversely into the an...
