Abstract
The present invention pertains to a flexible organic polymeric optical fiber core having an adherent flexible organic polymer cladding on the outer surface. More particularly, the invention relates to an organic polymeric optical fiber having a polyureasiloxane copolymer, polyurethane-siloxane copolymer, or polyurethaneurea-siloxane copolymer cladding for in vivo use in the tissue of a living mammal, preferably a human being. In addition to compatibility in live tissue and body fluids, the fiber must be capable of repeatedly being deformed in a small bend radius without losing the ability to transmit light. The clad optical fibers useful to measure levels of components (e.g. pH, oxygen, carbon dioxide) in living, moving tissue, such as the heart or lungs.
