Patent number: 8708896Abstract: 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.Type: GrantFiled: February 1, 2011Date of Patent: April 29, 2014Assignee: Invuity, Inc.Inventors: Alex Vayser, Kenneth B. Trauner, Jonathan G. Gasson, Thomas L. Grey

Patent number: 8688401Abstract: In certain embodiments, determining an endoilluminator output includes calculating an illuminator contribution of an endoilluminator system and a fiber contribution of one or more optical fibers of the endoilluminator system. The endoilluminator output is determined from the illuminator contribution and the fiber contribution. The illuminator contribution may be established using calibrated or empirically determined factors, such as an illuminator leg efficiency, an attenuator factor, an initial lamp performance, and/or a lamp performance degradation factor of the lamp. The fiber contribution may be established using calibrated or empirically determined factors, such as a fiber coupling factor and/or fiber transmission ratio of the optical fibers.Type: GrantFiled: December 22, 2011Date of Patent: April 1, 2014Assignee: Alcon Research, Ltd.Inventors: Michael J.
