ABSTRACT:
The present invention is directed to a novel laser catheter assembly including a unitary connector for coupling a laser beam in proper alignment with an optical fiber. An optical fiber assembly comprising an optical fiber interposed within a catheter tube is permanently mounted to the connector which is of one-piece molded construction. A presently preferred embodiment of the connector has an axial bore at the proximal end thereof of substantially the same diameter as the optical fiber, and a second bore larger than the diameter of the fiber, the second bore being in communication with a source of coolant. In a preferred embodiment the connector is further provided with a cavity in the area about the proximal tip of the optical fiber so as to minimize fouling of the fiber tip in the event of misalignment of the laser beam.
