Patent number: 11166782Abstract: Implantable magnetic markers (seeds) provide a higher degree of flexibility and convenience. The magnetic field that a marker provides is determined by the magnetic properties of the materials used and the dimensions of the marker—in general, a larger marker is easier to locate. Larger diameter markers may be used, but they should be much smaller than the average tumor size if they are to provide a useful degree of localization. An implantable magnetic marker is provided with two or more magnetic elements comprising permanent magnets connected by a mechanical connector to resiliently retain a first orientation when deployed and a second orientation before and/or during implantation. This allows complex magnetic configurations to be implanted, while retaining a simplified implantation method independent of the number of magnetic elements used.Type: GrantFiled: September 15, 2020Date of Patent: November 9, 2021Inventors: Bram Schermers, Adrianus Cornelis Petrus Van Leijsen, Hubert Cecile Francois Martens

Patent number: 11071460Abstract: In a photoacoustic measurement apparatus and a photoacoustic measurement system, it is possible to generate blood flow information using a photoacoustic image without requiring a separate tourniquet. A light source emits measurement light. A probe detects a photoacoustic wave generated in a subject after measurement light is emitted to the subject in each of the avascularized condition in which the subject is avascularized and the non-avascularized condition in which the subject is not avascularized. Photoacoustic image generation unit generates a photoacoustic image based on the detection signal of the photoacoustic wave. Blood flow information generation unit generates blood flow information based on the signal value of a photoacoustic image in a region of interest set in the photoacoustic image. The avascularization of the subject is performed by pressing the probe against the subject.Type: GrantFiled: June 30, 2017Date of Patent: July 27, 2021Assignee: FUJIFILM CorporationInventors: Kaku Irisawa, Dai Murakoshi, Tetsuro Ebata, Shoji Hara

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: 11020016Abstract: An image display system is provided comprised of a virtual window system that creates a visual coherency between the patient's anatomical images and the actual patient by aligning the image on the display to the patient and then presenting the image to the user in a way that feels as if the user is looking directly into the patient through the display. The image shown within the image display system is dependent upon the position of the image display apparatus and the position of the user so that the display orientation of the image may be biased slightly toward the user to improve ergonomics and usability.Type: GrantFiled: May 23, 2014Date of Patent: June 1, 2021Assignee: Auris Health, Inc.Inventors: Daniel Wallace, Gregory Stahler, Aaron Grogan
