PROBLEM TO BE SOLVED: To provide a penetrating member with direct visualization.SOLUTION: An embodiment for accessing the spine includes 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 to visualize the tissue as the access pathway is formed by the tissue penetrating members. 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. |
