Abstract

There is provided an applicator cartridge for delivery of a photoactivatable composition to a treatment site, having an applicator head and a reservoir adapted to receive the composition, which may be used with a photodynamic therapy device comprising an illuminating member. Methods of using the applicator cartridge and the device are also provided.

First claim

The invention claimed is:

1. A phototherapy device comprising:
an illuminating member comprising an illuminating element and a power source electrically connected thereto; and
a light permeable cartridge comprising an applicator head having a planar surface at a distal end, an absorbent pad placed onto the planar surface of the applicator head, and a reservoir adapted to receive therein a composition, wherein the applicator head comprises one or more pores for passing the composition from the reservoir through the applicator head onto a treatment site, wherein the light permeable cartridge allows passage of actinic light from the illuminating element to the treatment site, wherein the cartridge is detachably connected to the illuminating member, and wherein when the cartridge is connected to the illuminating member, the reservoir is positioned between the applicator head and the illuminating member.

2. The device of claim 1 , wherein the device is a hand-held device.

3. The device of claim 1 , wherein the cartridge comprises a mounting member for mounting the cartridge on the illuminating member.

4. The device of claim 3 , wherein the mounting member is threaded.

5. The device of claim 3 , wherein the mounting member includes a clip.

6. The device of claim 1 , wherein the applicator head comprises a plurality of fingers extending from the distal end of the applicator head.

7. The device of claim 1 , wherein the cartridge comprises a removable cover member adapted to cover the applicator head.

8. The device of claim 7 , wherein the removable cover member is coated with a composition.

9. The device of claim 8 , wherein the composition coating the removable cover member comprises a photoactivator and/or an oxidant.

10. The device of claim 7 , wherein the removable cover member is impermeable to light.

11. The device of claim 1 , wherein the cartridge is made from a flexible material.

12. The device of claim 1 , wherein the cartridge is made from an inert material.

13. The device of claim 1 , wherein the distance between the illuminating element and the applicator head is 0-10 cm.

14. The device of claim 1 , wherein the illuminating member further comprises a waveguide, the waveguide being connected to the illuminating element.

15. The device of claim 14 , wherein the waveguide comprises at least one optical fiber.

16. The device of claim 14 , wherein the waveguide comprises at least one light pipe.

17. The device of claim 1 , wherein the illuminating element is a light emitting diode (LED).

18. The device of claim 17 , wherein the LED is configured to emit an actinic visible light.

19. The device of claim 1 , wherein the illuminating element is configured to emit an actinic continuous light.

20. The device of claim 1 , wherein the illuminating element is configured to emit an actinic pulsed light.

21. The device of claim 1 , wherein the device can be hand mounted or finger mounted.

22. The device of claim 1 , wherein the reservoir and/or the cartridge is removable.

23. The device of claim 1 , further comprising one or more actuator buttons for controlling the illuminating element and/or for pushing a composition in the reservoir through the one or more pores.

24. The device of claim 1 , wherein the cartridge is configured to push through a composition in the reservoir through the pores of the applicator head when a pressure is applied to the cartridge.

25. The device of claim 1 , further comprising a composition in the reservoir, said composition comprising a photoactivator and/or an oxidant.

26. The device of claim 1 , wherein the composition comprises a xanthene or xanthene derivative.
