Publication number: 20210307860Abstract: A conductor-less, shape-able, surgical lighting system and methods for use in surgical applications in which a medical clinician, once having established a surgical site, can shape the lighting system to selectively illuminate desired volumes of the surgical site. The system includes preselected lengths of an elongate light emitting member formed of a transparent elastomer matrix material having a glass transition temperature of lower than or substantially equal to room temperature to render the elongate light emitting member bendable and shape-able. Embedded in the transparent elastomer matrix material are particles of a transparent material having a refractive index different from a refractive index of the matrix material dispersed in the elastomer matrix material so that light coupled into the elongate light emitting member is scattered and refracted out of the elongate light emitting member along its length. One end of the elongate light emitting member is coupled with a light source.Type: ApplicationFiled: June 16, 2021Publication date: October 7, 2021Applicant: SYNAPTIVE MEDICAL INC.Inventors: Siu Wai Jacky Mak, Michael Frank Gunter Wood
