Abstract:
1. A surgery light transmitting apparatus comprising: an optic fiber having a length between opposite proximal and distal end surfaces, the optic fiber length having a proximal portion adjacent the optic fiber proximal end surface that has a first cross-sectional area, the optic fiber length having an intermediate portion adjacent the proximal portion that has a second cross-sectional area that is smaller than the first cross-sectional area, the optic fiber length having a distal portion adjacent the optic fiber distal end surface that has a third cross-sectional area that is smaller than the second cross-sectional area, where the intermediate portion of the optic fiber length extends along a majority of the optic fiber length between the proximal and distal end surfaces; and, the first-cross-sectional area being constant along the proximal portion of the optic fiber length, the second cross-sectional area being constant along the intermediate portion of the optic fiber length, and the third cross-sectional area being constant along the distal portion of the optic fiber length.
