Abstract: A system and method for treating a fluid carrying a contaminant to which a photoactive material has been bound include a treatment device that defines a flow passage with a gap. The system and method operate to establish a flow of fluid from the inlet end of the gap to the outlet end of the gap. The system and method also channel the flow of fluid in the gap in succession through one or more flow paths. The system and method establish at least two discrete sources of radiation in the flow path at spaced apart locations along the direction of fluid flow. At least one of the radiation sources comprises a photodiode. The system and method further include a control for operating each discrete source of radiation at a selected wavelength within the prescribed range to activate the photoactive material bound to the contaminant. Upon activation, the material eradicates the contaminant. The system and method provide extracorporeal treatment of fluids like blood to quickly and effectively eradicate infection agents at relatively high flow rates.

Abstract: A system (10) and method for treating a fluid carrying a contaminant to which a photoactive material has been bound include a treatment device (12) that defines a flow passage (36) with a dap (28). The system and method operate to establish a flow of fluid from the inlet (38) end of the gap (28) to the outlet end (40) of the, gap (28). The system and method also channel he flow of fluid in the gap (28) in succession through one or more paths. The system and method esta- blished at least two discrete sources of ra- diation (30), in the flow path (36) at spaced, apart locations along the direc- lion of fluid flow. At least one of the ra- diation sources (30) comprises a photodi- ode. The system and method further in- clude a control far operating each dis- crete source of radiation at a selected wavelength within the prescribed range to activate the photoactive material bound to the contaminant. Upon activa- tion, the material eradicates the contami- nant. The system and method provide ex- tracorporeal treatment of fluids like blood to quickly and effectively eradicate infection agents at relatively high flow rates.
