| abstract |
A fiber optic unit to ablate tissue with light is described. The unit may include a bundle of optical fibers having a bundle proximal end adaptable to a light source, and a hardened bundle distal end though which the light exits to reach the tissue. The unit may also include hard materials, such as metal or glass, formed around the distal ends of each of the optical fibers. The hard coatings may be fused or swaged to bond the distal ends of the optical fibers together. |
