Paper Abstract

We sought to compare the properties of cylindrical and ball tip fibers (in conjunction with a holmium:YAG laser) by examining both their beam characteristics and the characteristics of the channels formed when the fibers passed through myocardial tissue. We found that the cylindrical fiber tip was able to produce a wider, more uniform channel with less surrounding thermal damage than the ball tip fiber. We attribute these findings to the shorter focal length, smaller beam spot size, and greater beam divergence produced by the ball tip fiber.
