Latest Patents

Matsuyuki Doi holds a patent for an evanescent catheter system. This system features a tip portion of an optical fiber that can securely measure fluorescence intensity or fluorescence spectrum of substances around the catheter tip. It effectively overcomes the challenges posed by the optical absorption of hemoglobin in erythrocytes in blood. The design allows for the calculation of the existing amount of a fluorescence-emitting substance in the evanescent light generating part. The catheter's tip has a core that is exposed by removing a protecting layer and cladding from its upper semicircular part. When excitation light is incident, evanescent light is generated, and a fluorescent substance emits fluorescence. An interference filter ensures that only the fluorescence reaches the photodiode, enabling accurate measurement of the fluorescent substance.
