Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
102 words
A light array assembly for use in a patient treatment system for altering cells including treating the cells with a photoactivatable agent and irradiating said cells and said agent whereby said agent is caused to be activated and to affect said cells, said agent and said cells during irradiation being contained in an irradiation chamber, comprising a top printed circuit board and a bottom printed circuit board having mounted therebetween and connected thereto a plurality of radiation sources for providing photoactivating illumination, each of said printed circuit boards having a plurality of contacts adapted to receive power for energizing said radiation sources.
Claim 2
Dependent Claim
102 words
A light array assembly for use in a patient treatment system for altering cells including treating the cells with a photoactivatable agent and irradiating said cells and said agent whereby said agent is caused to be activated and to affect said cells, said agent and said cells during irradiation being contained in an irradiation chamber, comprising a top printed circuit board and a bottom printed circuit board having mounted therebetween and connected thereto a plurality of radiation sources for providing photoactivating illumination, each of said printed circuit boards having a plurality of contacts adapted to receive power for energizing said radiation sources.
Claim 3
Dependent Claim
48 words
The assembly as described in claim 1 wherein said circuit boards further comprise plated circuitry, said irradiation sources are of tubular design, each end thereof containing at least one contact pin for receiving power, and wherein said plated circuitry connects said pins to said means for receiving power.
Claim 4
Dependent Claim
18 words
The array of claim 2 wherein said circuit boards further comprise track means for receiving said irradiation chamber.
Claim 5
Dependent Claim
20 words
The array of claim 3 wherein said array further comprises integrated circuit means for providing information characteristic for said array.
Claim 6
Dependent Claim
60 words
The array as described in claim 4 wherein said plurality of irradiation sources are arranged to have a planar space therebetween for receiving said irradiation chamber and wherein said track means passes between said plurality of irradiation sources, and wherein said circuit board means further comprises orientation means for preventing incorrect mounting of said array in said patient treatment system.
Claim 7
Dependent Claim
12 words
The array of claim 2 wherein said irradiation sources provide ultraviolet radiation.
