Abstract

A flexible tip (10) for a medical catheter suit-able for the transmission of light and dimensionned to pass through extremely small tubular members is described. The flexible tip, preferably made of optically transparent silicone elastomer (13), is af-fixed to the terminal end of a conventional optical fiber. In a preferred embodiment, the flexible tip comprises a central silicone core (11) surrounded by a cladding (12) having an index of refraction less than that of the core (11), permitting internal reflection. The flexible tip is provided with an outer jacket (13) which serves two purposes: (1) it pro-vides structural integrity for the tip; and (2) it re-inforces the union between the flexible tip and the optical fiber to which it is abutted. The tip (10) en-ables the delivery of a comparable amount of light as a large glass fiber of equal core diameter but pos-sesses much greater flexibility. The tip (10) has the flexibility to be able to enter tortuous tubular mem-bers while retaining the light transmitting capabili-ties of relatively inflexible glass optical waveguides of the same diameter.
