Abstract
In a fiber-optic probe for intravascular measurements, e.g. oxygen saturation measurements, the fiber-optical core has only two fibers. A single fiber core is also possible. A reinforcement fiber improves stiffness, kink resistance and overall strength of the probe. The reinforcement fiber is arranged essentially parallel to the core fibers. The reinforcement fiber may also be wound around the core in a helical manner thus improving the mechanical properties to an even higher degree. The outside of the sheath is coated with an antithrombogenic coating for reducing the danger of clots forming at the surface. The reinforcement fiber may be made of carbon, metal, ceramics or aramide.
