Photo-activatable formulation applicator
An applicator device includes a formulation assembly with a dispenser portion and one or more formulation reservoirs, the formulation assembly being operable to dispense a formulation from the one or more formulation reservoirs onto one or more regions of a biological surface. The applicator device also includes a photo-dose assembly operably coupled to the formulation assembly, the photo-dose assembly having at least one illuminator oriented to focus electromagnetic energy onto one or more focal regions of a biological surface.
1. An applicator device, comprising:
a formulation assembly including a dispenser portion and one more formulation reservoirs, wherein the one or more formulation reservoirs include a formulation, and the formulation assembly is operable to dispense the formulation from the one or more formulation reservoirs onto one or more regions of a biological surface; and
a photo-dose assembly operably coupled to the formulation assembly, the photo-dose assembly including at least one illuminator oriented to focus electromagnetic energy onto the one or more regions of the biological surface;
a light ring disposed proximate the dispenser portion and positioned so that the dispenser portion is concentric with the light ring; and
at least one waveguide structure optically coupled to the light ring and configured to transmit the focused electromagnetic energy from the at least one illuminator to the light ring, and wherein the light ring is configured to emit the focused electromagnetic energy out of the applicator device.
2. The applicator device of claim 1 , wherein the one or more formulation reservoirs include at least one replaceable formulation cartridge.
3. The applicator device of claim 2 , wherein the formulation cartridge is removably couplable to the applicator device by releasable coupling means.
