Tissue filler compositions and methods of use
The present disclosure relates to methods for stimulating collagen synthesis, cosmetic enhancement of soft tissue and/or inhibiting or treating scarring comprising administering a composition to an area to be treated within a soft tissue, wherein the composition comprises a tissue filler medium and a fluorophore; and illuminating the area with light having a wavelength which can be absorbed by the fluorophore.
1. A method for promoting wound healing, the method comprising:
administering a composition to a wound area to be treated, wherein the composition comprises a tissue filler medium and a fluorophore; and wherein the composition is non-photopolymerizable; and
illuminating the wound area to be treated with light having a wavelength which can be absorbed by the fluorophore;
wherein the method promotes wound healing in the wound area.
2. The method of claim 1 , wherein the wound area to be treated is soft tissue.
3. The method of claim 1 , wherein the administering of the composition is by injection.
4. The method of claim 1 , wherein the administering of the composition is by implantation.
5. The method of claim 1 , wherein the composition is selected in a form selected from a cohesive gel and a hydrated gel.
6. The method of claim 1 , wherein the tissue filler is a dermal filler.
7. The method of claim 1 , wherein the tissue filler medium comprises a polymer.
8. The method of claim 7 , wherein the polymer is selected from proteins, peptides, polypeptides, polylysine, collagens, pro-collagens, elastins, and laminins.
9. The method of claim 7 , wherein the polymer is selected from poly(vinyl alcohol), polyethylene glycol, polyvinlyl amine, polyallylamine, deacetylated polyacrylamide, polyacrylic acid, and polymethacrylic acid.
10. The method of claim 1 , wherein the tissue filler medium comprises cross-linked hyaluronic acid.
11. The method of claim 10 , wherein the cross-linked hyaluronic acid is in particulate form.
12. The method of claim 1 , wherein the composition further comprises light reflecting particles.
13. The method of claim 1 , wherein the composition further comprises an injectable medium supporting the particles.
14. The method of claim 13 , wherein the injectable medium comprises hyaluronic acid which is relatively less cross-linked than the hyaluronic acid in particulate form.
15. The method of claim 1 , wherein the composition is transparent or translucent.
16. The method of claim 1 , wherein the tissue filler medium retains the fluorophore within the composition during administering of the composition, and at least during a portion of the illumination.
17. The method of claim 1 , wherein the tissue filler medium is biodegradable.
18. The method of claim 1 , wherein the fluorophore can be activated by light having a wavelength in the visible range.
19. The method of claim 1 , wherein the fluorophore is not in a liposomal form in the composition.
20. The method of claim 1 , wherein the wound is an amputation, a burn, an incision, an excision, a lesion, a laceration, an abrasion, a puncture wound, a penetrating wound, a surgical wound, a contusion, a hematoma, a crushing injury, a pressure ulcer, a venous ulcer, an arterial ulcer, a diabetic ulcer, or a wound caused by periodontitis.
