Abstract:
1. A catheter for illuminating at least a portion of a lumen of a subject, comprising: a flexible light bar including a cylindrical polymer encasement portion having a maximum cross-sectional diameter that is less than about 1.5 mm, wherein the polymer encasement portion completely encases the plurality of light emitters and the electrical connections, wherein the at least one S-shaped portion of the electrical connections provides an offset arrangement for adjacent light emitters such that the adjacent light emitters overlap when viewed along a longitudinal axis of the polymer encasement portion to reduce a diameter of the polymer encasement portion, wherein the longitudinal axis of the polymer encasement portion intersects at least a portion of each adjacent light emitter; wherein the electrical connections connect the light emitters without the use of a planar mounting strip extending along most of a length of the light bar such that only the polymer encasement portion and the electrical connections mechanically couple the plurality of light emitters together.
