Abstract
Illuminated surgical retractors include at least one retractor blade and a light delivery system. In some embodiments of the invention, the light delivery system includes a light emitter in the form of an elongated light emitting blade portion extending along the length of the retractor blade. The light emitter may be coupled to a light source integral with the retractor for illuminating all or a portion of the length of the light emitter or retractor blade. In other embodiments of the invention, the light delivery system may include an array of lights which may be attached directly to the retractor blade or to a support in the shape of an elongated blade that extends along the length of the retractor blade for illuminating all or a portion of the length of the retractor blade.
