Patent number: 9005115Abstract: An illumination system includes 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 be 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: August 7, 2008Date of Patent: April 14, 2015Assignee: Invuity, Inc.Inventor: Alex Vayser

Publication number: 20150057504Abstract: A surgical clip for illuminating tissue in a surgical field has first and second elongate arms and a connector joining the arms together. The arms are biased to expand laterally outward into an expanded configuration in which the arms engage the tissue in the surgical field with enough force to seat the clip without retracting the tissue. A waveguide illuminator is coupled to the first arm, and has a light input portion, a light output portion, and a light conducting portion extending between the light input portion and the light output portion. Light passes through the waveguide illuminator by total internal reflection, and the waveguide illuminator directs light to the tissue. Methods of using the illuminated clip are also disclosed.Type: ApplicationFiled: October 30, 2014Publication date: February 26, 2015Applicant: Invuity, Inc.Inventors: Alex Vayser, Anant Hegde, Douglas Rimer

Patent number: 8920316Abstract: 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.Type: GrantFiled: August 31, 2011Date of Patent: December 30, 2014Assignee: Invuity, Inc.Inventors: Thomas L.

Patent number: 8876709Abstract: A surgical retractor for illuminating a surgical field includes an ergonomic handle, a retractor blade coupled with the handle, a quick release mechanism, and an illuminator blade. The retractor blade is adapted to engage and retract tissue, and the quick release mechanism is adapted to couple the handle with the retractor blade. The illuminator blade acts as a waveguide to transmit light by total internal reflection. Light is extracted from the illuminator to illuminate the surgical field. The retractor blade is releasable from the handle without requiring uncoupling of the illuminator blade from the handle and also without requiring optical uncoupling of the illuminator blade from a light source. The retractor may also be adapted to evacuate smoke from the surgical field.Type: GrantFiled: September 21, 2012Date of Patent: November 4, 2014Assignee: Invuity, Inc.Inventors: Alex Vayser, Douglas Rimer, Stephen DeSantis
