Abstract: The present invention provides devices and methods of manufacture related to transmitting light to a target site for diffusion Techniques are provided which allow accurate control of the illumination profile with a diffuser tip design which is easily producible, relatively inexpensive, and provides variations to obtain desired illumination profiles. This is achieved by using at least two light scattering mediums having a shape defined by an insert. The dimensions, light scattering properties, and number of such light scattering mediums may be selected individually or collectively to selectively control the illumination profile. In addition, the insert allows for other beneficial design features, such as a reduced heat retention, easily controlled and refined light scattering medium interfaces, and a smaller cross-sectional diameter than is typically achievable with other techniques.

Abstract: A laser fiber apparatus and method for preparing the apparatus is described herein. An apparatus comprising a laser fiber having a proximal end, a distal end, a core, and a cladding. A lens at the distal end of the laser fiber is proximally elongated from bulbous in shape. The core of the laser fiber transmits laser energy from a laser source coupled to the proximal end through the lens. The cladding of the laser fiber also circumferentially coats at least the proximally elongated portion of the lens, and epoxy material circumferentially coats the cladding, a portion of the lens distal the cladding, and defines an aperture at the apex of the lens.
