Problems solved by technology

These anatomies make it difficult to treat or diagnose conditions within the epidural area, as they tend to collapse around any instrument or device inserted therein
This reduces visualization in the epidural space and may produce inadvertent damage to the nerve root during device insertion
Additionally, insertion of a viewing device can result in obstructed or reduced viewing capabilities
Thus, many anatomical components within the epidural space limit the insertion, movement, and visualization capabilities of any access, visualization, diagnostic, or therapeutic device inserted into the epidural space

Embodiment Construction

[0022] In order to reduce damage to the spinal structure while maintaining bone strength, minimally invasive spinal surgery has been used to avoid removing the native bone and / or cutting the surrounding native tissue. The existing minimally invasive spinal approach surgery is performed using fluorescence guidance and endoscopic observation. Although existing spinal endoscopy systems provide the ability to observe the treatment area directly when approaching the spine or other areas of the body, these systems are often accompanied by the risk of iatrogenic damage to nerves and vessels Or the difficulty of locating the target part. Similar risks and difficulties are also associated with many other minimally invasive and restricted access procedures, including but not limited to, for example, placement of the subclavian internal jugular vein catheter, kidney biopsy, liver biopsy, puncture, thoracentesis The surgery is close to the femoral artery.

[0023] The root of these risks m...

Abstract

Systems and methods for accessing the spine include tissue penetrating members with direct visualization capability that may be used to form an access pathway to a targeted treatment site. The direct visualization capability, which may be provided by fiberoptic illumination and imaging components, may be used for making the tissue visible as the access pathway is formed by the tissue penetrating member. The tissue penetrating members include catheters and cannulas with sharpened tips with integrated fiberoptic components and / or channels in which a fiberscope or miniscope may be inserted. Apertures and / or transparent materials are provided to permit imaging of tissue about the distal end of the tissue penetrating member.

Description

[0001] Cross references to related applications [0002] This application claims the priority of U.S. Provisional Application No. 61 / 084,202 filed on July 28, 2008 in accordance with 35 U.S.C. §119(e), the disclosure of which is hereby incorporated by reference in its entirety. Background technique [0003] Damaged intervertebral discs are usually treated with bed rest, physical therapy, repair behavior, and pain medication for long-term treatment. There are also a variety of treatments that try to repair damaged discs and avoid surgical removal of the damaged discs. For example, intervertebral disc decompression is a surgical method used to remove or shrink the nucleus pulposus, thereby reducing and reducing the pressure on the annulus and nerves. Less invasive surgical methods such as minimally invasive lumbar discectomy and automatic percutaneous lumbar discectomy remove the nucleus pulposus of the vertebral disc by aspiration through a needle inserted laterally into the disc a...
