Abstract
A direct vision cryosurgical and methods of use are described herein where the device may generally comprise an elongated rigid structure with a distal end, a proximal end, and a central lumen. The distal end may comprise a non-coring optically transparent needle tip with at least one lateral fenestration in communication with the central lumen. The distal end may also house at least one imaging device configured for distal imaging. A proximal end of the device may comprise a handle with a means for connecting the imaging device(s) to an imaging display(s), and a means for accessing bodily tissue in the vicinity of the distal end with a cryo-ablation probe through the central lumen and the lateral fenestration(s) for diagnostic or therapeutic purposes.
