Patent number: 12036012Abstract: A sensor is provided for measuring a flow of a fluid in a physiological environment, such as within a vessel of a human or animal subject. The sensor comprises an interrogation light guide extending from a proximal end to a distal end of the sensor. The interrogation light guide is configured to transmit interrogation light to, and receive reflected interrogation light from, the distal end of the sensor. The sensor further comprises an excitation light guide configured to transmit excitation light to the distal end of the sensor. The excitation light is provided for heating the fluid (directly or indirectly). The sensor further comprises a sensing element located at the distal end of the sensor.

Publication number: 20210251605Abstract: An ultrasound probe comprises an optical light guide comprising a multi-mode optical waveguide for transmitting excitation light and a single-mode optical waveguide for transmitting interrogation light. The probe further comprises an ultrasound transmitter located at a distal end of the probe, the ultrasound transmitter comprising an optically absorbing material for absorbing the excitation light from the multi-mode optical waveguide to generate an ultrasound beam via the photoacoustic effect. The probe further comprises an ultrasound receiver including an optical cavity external to the single-mode optical waveguide. The interrogation light from the single-mode optical waveguide is provided to the ultrasound receiver. The optical cavity has a reflectivity that is modulated by impinging ultrasound waves. The interrogation light is reflected from the optical cavity to a proximal end of the single-mode optical waveguide where it can be received for generating a signal.Type: ApplicationFiled: June 14, 2019Publication date: August 19, 2021Applicant: UCL BUSINESS LTDInventors: Adrien DESJARDINS, Richard COLCHESTER, Malcolm FINLAY, Charles Alexander MOSSE, Sacha NOIMARK, Ioannis PAPAKONSTANTINOU

Patent number: 11039750Abstract: Needle interventions are widely used in the field of oncology for taking biopsies of tissue in order to inspect whether tissue is cancerous or not. To make these interventions more reliable feedback of what kind of tissue is in front of the needle is required. A way to achieve this is by making use of optical spectroscopy. This requires integration of fibers into the needle. These fibers are used to deliver light to illuminate the tissue in front of the needle and to collect back the reflected light from the tissue. The present invention proposes to integrate the fiber distal ends in the slanted bevel of the needle in such a way that at least one source-detector fiber pair has a distance that is larger than the outer diameter of the needle.Type: GrantFiled: September 12, 2016Date of Patent: June 22, 2021Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Bernardus Hendrikus Wilhelmus Hendriks, Augustinus Laurentius Braun, Rik Harbers, Marjolein Van Der Voort, Adrien Desjardins, Rami Nachabe

Patent number: 8812080Abstract: Needles are widely used in interventional radiology. Each medical application requires a specific needle type. The same holds for the photonic needles which analysis depends on the type of application the clinician aims for. Therefore, it is relevant to have the X-ray machine recognize the type of needle that is being used and to load the required software for the tissue analysis. It is therefore proposed to have a data link established between the imaging modality used for the acquisition of the patient anatomy (X-ray, CT, MR or US) and the system that processes optical data from the needle, so that the information from this imaging modality can be used to guide the processing. In a preferred embodiment the selection is made by reading out the code present in the disposable needle when it is connected to the console.Type: GrantFiled: June 7, 2010Date of Patent: August 19, 2014Assignee: Koninklijke Philips N.V.Inventors: Rami Nachabe, Bernardus Hendrikus Wilhelmus Hendriks, Augustinus Laurentius Braun, Marjolein Van Der Voort, Adrien Desjardins, Drazenko Babic, Nenad Mihajlovic
