Patent ID: 8685005

Claim:
A catheter assembly for performing light therapy on a subject, the assembly comprising: a control system adapted to be operated by a user; a catheter body extending from the control system, the catheter body dimensioned for placement within the subject; and a distal tip at an end of the catheter body, the distal tip including a transparent substrate having a plurality of locking features, wherein the transparent substrate is a substantially flat strip, wherein the entire flat strip comprises a transparent material, an array of spaced apart light sources for emitting light mounted on the flat strip and controlled by the control system, and a flexible outer member encapsulating both the substrate and the light sources, wherein portions of the flexible outer member pass through the locking features to lock the flexible outer member to the substrate, wherein the substantially flat strip carries a conductive connector adapted to provide power to the array of light sources and transmits most of the light emitted from the array of light sources towards the substrate such that a sufficient amount of light is transmitted through the substrate and the outer member to activate a therapeutically effective amount of treatment agent in the subject.
