Aspects of the invention include minimally invasive internal target tissue
site imaging devices. Devices according to embodiments of the invention
include an elongate member dimensioned to access an internal target
tissue location, e.g., an intervertebral disc, and having a proximal end
and a distal end; a white light source at the distal end; a
near-infra-red light source the distal end; and an imaging sensor at the
distal end. Also provided are methods of using the systems in imaging
applications, as well as kits for performing the methods.
