Fiber optics is successfully used in various areas of medicine, including urology, general surgery, ophthalmology,cardiology, endoscopy, dentistry and medical sensing [1 – 4]. One highly useful characteristic of optical fibers is their ability to enter the tiny passageways and hard-to-reach areas of the human body. Hence most medical applications require optical fibers to be relatively small and flexible so as to negotiate the complex curved anatomy of central spaces of vessels in-vivo: such as arteries, veins, gastrointestinal tracts, bronchi, and urinary tracts.|Fiber optics is successfully used in various areas of medicine, including urology, general surgery, ophthalmology,cardiology, endoscopy, dentistry and medical sensing [1 – 4].
