| 20090182202 | Optical Waveguide Sheath - The illumination system is a cannula comprising a transparent or semi-transparent material capable of carrying light from the proximal end of the cannula to the distal end of the cannula, thereby illuminating a surgical field. The surgical field is thus illuminated through components that do not occupy space that may otherwise by used for optics and or surgical tools. The illumination source may be optically coupled with the cannula at any appropriate location. The cannula comprises a sterilizable polymer which functions as a waveguide. A waveguide is a material medium that confines and guides light. When in use, the light source connected to the hub provides light which may be guided to the distal end of the cannula or any other suitable location. Thus, the sheath provides structure-guided illumination resulting in the illumination of the surgical site. | 07-16-2009 |

| 20090112068 | Blade Insert Illuminator - An air gap retractor illumination system includes any suitable retractor such as a McCulloch with a channel in the blade to accommodate an air gap illuminator. The illuminator is preferably made from a suitable light conducting plastic material such as acrylic or polycarbonate or silicone. The illuminator has active portions in which light passes and inactive or dead zones in which light does not pass as a result of the configuration and orientation of the input, output and surfaces of the illuminator. The illuminator is formed to have an air gap surrounding any active portion of the illuminator extending from the light input to the light output portion. The dead zones may include elements to allow the illuminator to securely engage the retractor. The light output portion of the illuminator contains from two to eight output zones, each zone having specially designed output optical structures that control and direct light to escape the illuminator to shine onto a predetermined area of interest or to form one or more predetermined shapes or footprints. | 04-30-2009 |
| 20110201889 | ILLUMINATED CANNULA - The illumination system comprises an arthroscope, endoscope or other suitable surgical tool and an attachable cannula comprising a transparent or semi-transparent material capable of carrying light from the proximal end of the cannula to the distal end of the cannula, thereby illuminating the surgical field. The surgical field is thus illuminated through components that do not occupy space that may otherwise by used for the optics of the arthroscope. The arthroscopic illumination system further comprises one or more illumination sources disposed at the proximal end of the cannula. The illumination source may be optically coupled with the cannula at the hub or other appropriate location. The cannula comprises a sterilizable polymer which functions as a waveguide. A waveguide is a material medium that confines and guides light. When in use, the light source connected to the hub provides light which may be guided to the distal end of the cannula or any other suitable location. Thus, the sheath provides structure-guided illumination resulting in the illumination of the surgical site. | 08-18-2011 |

| 20110319720 | BLADE INSERT ILLUMINATOR - A blade insert illumination system includes one or more illumination elements composed of a transparent or semitransparent polymer that is preferably biocompatible and sterilizable. The illumination elements operate as a waveguide and may incorporate optical components such as, for example, facets, lenses, gratings, prisms and or diffusers to operate as precision optics for customized delivery of the light energy. The illumination elements may be modular, allowing components to be mixed and matched for different sizes of blade retractors, or may be a single integrated unit. | 12-29-2011 |
