1. A medical device comprising:
a hand piece;
an introducer extending from the hand piece;
a beam fiber; and
a beam disperser located at a distal end of the beam fiber, through which beam energy is dispersed, wherein the beam disperser has a polygonal shape and comprises a surface arranged around a longitudinal axis of the beam fiber and angled relative to the longitudinal axis, wherein the surface comprises a plurality of substantially planar faces arranged around the longitudinal axis of the beam fiber, and wherein the beam energy is dispersed from each of the planar faces at an angle relative to the longitudinal axis that is between 15 and 75 degrees;
wherein the beam fiber is at least partially located inside the introducer; and
wherein the beam fiber is movable relative to the introducer between a retracted position, wherein the beam disperser is disposed inside of the introducer and an extended position, wherein the beam disperser is disposed external to the introducer.
