Patent number: 11553852Abstract: A medical system for minimally-invasive measurement of blood flow in an artery (AT). An interventional device (IVD) with an optical fiber (FB) comprising a plurality of temperature-sensitive optical sensor segments, e.g. Fiber Bragg Gratings, spatially distributed along its longitudinal extension is configured for insertion into an artery (AT). A temperature changer (TC) is arranged in the WD to introduce a local change in temperature (?T) of a bolus of blood in the artery, to allow thermal tracking over time with the optical fiber (FB). A measurement unit (MU) with a laser light source (LS) delivers light to the optical fiber (FB) and receives light reflected from the optical fiber (FB) and generates a corresponding time varying output signal. A first algorithm (A1) translates this time varying output signal into a set of temperatures corresponding to temperatures at respective positions along the optical fiber (FB).Type: GrantFiled: May 29, 2012Date of Patent: January 17, 2023Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Gert Wim 'T Hooft, Adrien Emmanuel Desjardins, Maya Ella Barley, Raymond Chan

Patent number: 10105057Abstract: The present invention relates to an apparatus 100 and, a method and a computer program for determining a parameter indicative of a tissue type of an associated tissue 116. In particular, the invention relates to an apparatus 100 comprising a spectrometer 102, which spectrometer comprises a light source 104 and a detector 106, 108 arranged to measure an optical spectrum.
