Fiber and a device incorporating the fiber therein for use in treating tissue volumes

Image Number 4 for United States Patent #6113589.

A device for use in laser induced interstitial thermotherapy (LITT) is provided which includes a fiber for coupling to a laser energy source and an emitting element having a proximal end coupled to the fiber and a distal end for positioning adjacent to the surface receiving LITT, the emitting element radially emitting light whose intensity is controllable along its longitudinal length. In a preferred embodiment, the surface of the emitting element is roughened to achieve a power scattering function.
