Light delivery systems and related methods of use
The present disclosure provides for light delivery assemblies and, more particularly to light delivery assemblies/systems that provide light to and/or illuminate/treat predetermined locations (e.g., surgical sites), and related methods of use. An exemplary light delivery assembly (e.g., a surgical site light) includes a shell/housing (e.g., a plastic shell/housing) with a cross-sectional shape similar to an inward-facing asymmetrical C. The shell/housing is shaped to be placed proximal to a site (e.g., surgical site) and emit light onto the site from a plurality of directions while inhibiting the light from radiating away from the outside of the shell/housing. Exemplary light delivery assemblies of the present disclosure can be utilized for a variety of different applications/treatments/uses (e.g., surgical applications, disinfection/sterilization especially UV in the UVC wavelength range, other UV treatment, infrared heating and treatment, therapy, IR light delivery, use of all/other wavelengths of light, etc.).
1. A light delivery assembly comprising:
a shell having an asymmetrical C-shaped cross-sectional profile, the shell having an upper portion and a lower portion with the upper portion extending over the lower portion and extending further inwards than the lower portion to define the asymmetrical C-shaped cross-sectional profile of the shell, the C-shaped cross-sectional profile being asymmetrical about a plane including the boundary between the upper and lower portions;
a light source to deliver light into the shell;
wherein the shell is configured to at least partially surround a pre-determined location and diffuse the light inwards and downwards, via the asymmetrical C-shaped shell, toward the pre-determined location.
2.

4. The assembly of claim 1 , wherein the light source includes one or more light emitting diodes.
5. The assembly of claim 1 , wherein the light source includes an external light source having one or more light emitting diodes, the external light source mounted with respect to the shell via one or more cables or fibers.
6. The assembly of claim 1 , wherein the shell includes a connection feature to connect to the light source; and
wherein one or more light emitting diodes are mounted with respect to the connection feature, the one or more light emitting diodes of the connection feature configured to deliver light into the shell and to the pre-determined location.
7. The assembly of claim 1 , wherein the shell includes an inner surface; and
wherein one or more light emitting diodes are mounted with respect to the inner surface, the one or more light emitting diodes of the inner surface configured to deliver light into the shell and to the pre-determined location.
8. The assembly of claim 1 , wherein the shell defines an opening and includes a cover member configured and dimensioned to releasably mount with respect to the upper portion of the shell to cover the opening.
9. The assembly of claim 8 , wherein the cover member is configured and dimensioned to: (i) prevent light or radiation to escape from the upper portion of the shell, and (ii) direct light towards the pre-determined location.
10. The assembly of claim 8 , wherein one or more light emitting diodes are mounted with respect to a lower surface of the cover member, the one or more light emitting diodes configured to deliver light into the shell or to the pre-determined location.
11. The assembly of claim 8 , wherein one or more reflectors are mounted with respect to a lower surface of the cover member, the one or more reflectors configured to direct light toward the pre-determined location.
12. The assembly of claim 8 , wherein one or more optic fibers are mounted with respect to the cover member, each optic fiber in communication with an optical sensor; and
wherein the optical sensor is configured to detect areas of the pre-determined location that have been treated with dye material so that a specific frequency, intensity or duration of light can be delivered to areas treated with dye material via the one or more optic fibers.
13. The assembly of claim 12 , wherein the one or more optic fibers each include flat end portions that are mounted with respect to a lower surface of the cover member.
14. The assembly of claim 1 , wherein the wherein one or more optic fibers are mounted with respect to the shell, each optic fiber in communication with an optical sensor; and
wherein the optical sensor is configured to detect areas of the pre-determined location that have been treated with dye material so that a specific frequency, intensity or duration of light can be delivered to areas treated with dye material via the one or more optic fibers.
15. The assembly of claim 1 , wherein a window member is mounted with respect to the upper and lower portions of the shell, the window member configured to provide a bather between the shell and the pre-determined location while permitting light from the shell to pass through the window member and to the pre-determined location.
16. The assembly of claim 15 , wherein the window member is configured and dimensioned to: (i) diffuse the light from the shell to improve the quality of the light delivered to the pre-determined location, and (ii) enclose at least a portion of the shell to prevent contamination of the shell.
17. The assembly of claim 1 , wherein the shell includes a first shell member and a second shell member, the first and second shell members configured to mount with respect to one another to define the shell; and
wherein the first and second shell members are adjustable and movable relative to one another so that a user can change the size of the shell.
18. The assembly of claim 1 , wherein the shell is configured and dimensioned to be positioned in-line with a breathing/ventilator circuit so that as gases pass through the center of the shell, the gases are exposed to the light that is directed inwards via the shell.
19. A light delivery assembly comprising:
a shell having an asymmetrical C-shaped cross-sectional profile, the shell defining an opening and having an upper portion and a lower portion with the upper portion extending over the lower portion and extending further inwards than the lower portion to define the asymmetrical C-shaped cross-sectional profile of the shell, the C-shaped cross-sectional profile being asymmetrical about a plane including the boundary between the upper and lower portions;
a cover member configured and dimensioned to releasably mount with respect to the upper portion of the shell to cover the opening;
a light source to deliver light into the shell;
wherein the shell is configured to at least partially surround a pre-determined location and diffuse the light inwards and downwards, via the asymmetrical C-shaped shell, toward the pre-determined location;
wherein the cover member is configured and dimensioned to: (i) prevent light or radiation to escape from the upper portion of the shell, and (ii) direct light towards the pre-determined location;
