The present invention is directed to a system and method for photoeradication of microorganisms from a target. The method includes the step of obtaining test data for a plurality of experiments each of which comprises irradiating test microorganisms with a plurality of light pulses having a wavelength that ranges from 380 nm to 500 nm. The light pulses have a plurality of pulse parameters (peak irradiance, pulse duration, and off time between adjacent light pulses) and are provided at a radiant exposure that ranges from 0.5 J/cm.sup.2 to 60 J/cm.sup.2 during each of a plurality of irradiation sessions. The test data comprises a survival rate for the test microorganisms after irradiation with the light pulses. The method also includes the step of analyzing the test data to identify the pulse parameters for the light pulses and the radiant exposure for each of the irradiation sessions that result in a desired survival rate for the test microorganisms. The method further includes the step of irradiating the microorganisms of the target with light pulses having the identified pulse parameters at the identified radiant exposure for each of the irradiation sessions so as to photoeradicate all or a portion of the microorganisms.

A prosthetic liner for use with a prosthetic socket that has a thermoplastic elastomeric (TPE) layer that is in contact with the amputee's residual limb. The TPE layer is not uniform in thickness but has ridges to extend circumferentially around the TPE layer. A fabric exterior layer covers the outer surface of the TPE layer conforming to the ridges and is used as a substrate to form a mechanical bond to an elastomeric material. Impregnating the elastomeric material within the fabric exterior occurs by applying an uncured material to the fabric exterior layer and onto at least the apex surfaces located within the sealing regions thereby creating an air tight boundary layer when inserted into a socket. When a vacuum is applied the air is evacuated from the volume below the seal layer.

The device includes the use of a negative pressure bandage, a flexible light sheet, and one or more bioactive marine extracts. Light emitted from the flexible light sheet penetrates through the bandage to target damaged tissue, which accelerates the wound healing process and works synergistically with the negative pressure bandage and bioactive marine extracts such as collagen fibers, alginate, chitosan and fucoidan, or any combination thereof to accelerate healing.

ANTI-MICROBIAL IRRADIATION FOR PERCUTANEOUS OSSEOINTEGRATED PROSTHESES (POPs)

An osseointegrated fixture of a percutaneous osseointegrated prosthesis (POPs) anchors directly into a bone of a residual limb within an amputation stump. By anchoring directly into the bone, the POPs provides improved mobility, comfort, and function for an amputee, but an interface between an opening in the skin and the osseointegrated fixture, which allows the anchoring directly into the bone, is prone to infection by microbes. An anti-microbial device can be attached to and/or embedded within an extracorporeal portion of the osseointegrated fixture to irradiate at least a portion on the interface with at least one wavelength of light selected for its antimicrobial effects.
