Abstract
A phototherapy device which can include an optical fiber having a perfluorinated polymer outer buffer coating, and an optical element, such as a GRIN lens or a mirror, disposed at its distal end. A tubular housing encases the optical element and is thermally bonded to at least a portion of the buffer. The component elements of the device can be constructed of materials having similar thermal characteristic to inhibit the effect of heat cycling on the device. In addition, the materials of the device, and in particular the housing, can be selected to inhibit wear and scrapping of the lumen of the delivery instrument during use. A marker band can be positioned about the optical fiber to facilitate viewing of the phototherapy device in-vivo.
