Publication number: 20120245413Abstract: 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 be 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.Type: ApplicationFiled: March 26, 2012Publication date: September 27, 2012Applicant: Invuity, Inc.Inventors: Alex Vayser, Kenneth Trauner, Jon Gasson, Tom Grey

Publication number: 20120136216Abstract: An illuminator film system may include one or more pre-cut sections of optical film applied to a waveguide to allow light to exit the waveguide through the film in a predetermined manner. The one or more pre-cut sections may be removed and reapplied during a procedure to redirect the light. A laminated illuminator film may be provided that uses a laminated optical film structure to direct light from a fiber optic input. Such a laminated illuminator film may be very low profile, low cost and easy to apply to a retractor for providing illumination during a surgical procedure.Type: ApplicationFiled: February 3, 2012Publication date: May 31, 2012Applicant: Invuity, Inc.Inventors: Alex Vayser, Kenneth B.

Publication number: 20120116170Abstract: A soft tissue retractor includes a retractor body and a proximal projection extends generally perpendicular to the proximal end of the retractor body. An illumination waveguide engages a slot in the retractor blade to provide illumination to a surgical site while maintaining total internal reflection in the waveguide. An illumination input is formed into the proximal end of the illumination waveguide for conducting light from a source to the illumination waveguide. The proximal projection is configured for application of counter traction without the need for squeezing the retractor body. The proximal projection may be weighted to balance the soft tissue retractor as well as enabling the retractor to provide counter traction by itself. The configuration of the proximal projection further enables self-retraction by including a flat foot to prevent rolling and sliding of the retractor when it is providing self-retraction.Type: ApplicationFiled: October 5, 2011Publication date: May 10, 2012Applicant: Invuity, Inc.Inventors: Alex Vayser, Edward A. Covey, James K. Bredenkamp, Leland A. Stock

Publication number: 20120083663Abstract: An air gap retractor illumination system includes any suitable retractor with a channel in the blade to accommodate an air gap illuminator. The illuminator is preferably made from a suitable light conducting plastic material. The illuminator has active portions in which light passes and inactive or dead zones in which light does not pass. 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.Type: ApplicationFiled: November 18, 2011Publication date: April 5, 2012Applicant: Invuity, Inc.Inventors: Thomas L.

Patent number: 8088066Abstract: 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.Type: GrantFiled: October 24, 2007Date of Patent: January 3, 2012Assignee: Invuity, Inc.Inventors: Thomas L.
