ABSTRACT:
A fiber optic cable assembly in one embodiment includes an optical fiber, a jacket member axially surrounding the fiber, a connector for coupling the fiber to a source of laser radiation, a strain relief boot attached to the connector and axially surrounding a substantial length of the jacket and the optical fiber, and a support element axially surrounding the proximal end of the optical fiber and separating the jacket and connector from the fiber. In a second embodiment, the cable has first and second jacket portions and a third jacket portion rotatably coupled therebetween. The third jacket portion includes three tubular passages, two of which are arranged in axial alignment with the optical fiber and a third passage angularly connected to the first two and rotatable in an arc about the fiber axis. The third passage is operatively coupled to a fluid port which may be disposed at various arcuate positions about the fiber axis for fluid flow into the third passage. In a third embodiment, a laser delivery system includes an elongate fiber, a jacket member surrounding the fiber, and a plastic housing with a metal stem integrally molded therein. A central bore extends through the housing and into the metal stem to form a continuous bore into which the fiber is received.
