Claim Text:
1. A hand-held illuminated suction device comprising: a suction tube having a proximal portion and a distal portion; an optical waveguide having a proximal region and a distal region, wherein light is transmitted from the proximal region toward the distal region thereof by total internal reflection; a first handle coupled to the proximal portion of the suction tube and also coupled to the proximal region of the optical waveguide, wherein the first handle is disposed around the proximal region of the optical waveguide; and at least one total internal reflection (TIR) preserving feature coupled to the optical waveguide, wherein the at least one TIR preserving feature is configured to promote total internal reflection of the light passing through the optical waveguide.
