Publication number: 20180000424Abstract: Activity monitors and smart watches utilizing optical measurements are becoming widely popular, and users expect to get an increasingly accurate estimate of their heart rate (HR) from these devices.

Publication number: 20180000444Abstract: Apparatuses, systems, and methods for preclinical ultrasound imaging of subjects are provided. In one aspect, the apparatus can include a platform on which a subject is positionable and at least one motion stage for controlling a spatial position of at least one ultrasound transducer relative to the platform in order to acquire ultrasound image data of the subject. Methods for preclinical ultrasound raster scanning of at least one organ or tissue in a subject are also provided, where the at least one organ or tissue is a heart.Type: ApplicationFiled: January 25, 2016Publication date: January 4, 2018Inventors: Paul Alexander Dayton, Ryan Christopher Gessner, James Owen Butler, Max Stephan Harlacher, Nicholas Allan Norman

Publication number: 20180000445Abstract: Apparatuses, systems, and methods of monitoring lesion formation using one-dimensional echograms are disclosed. In certain aspects, lesion formation progress is monitored using the intensity of reflectors in successive echograms during ablation. In another aspect, lesion formation progress is monitored based upon actual or apparent movement of acoustic reflectors before and after ablation. In still another aspect, the presence or absence of resonant microbubbles known to populate forming lesions are used to provide feedback on lesion formation. A lesion analysis processor can be programmed to determine lesion formation progress using any of the foregoing approaches, either alone or in various combinations.Type: ApplicationFiled: January 4, 2016Publication date: January 4, 2018Inventors: John W. Sliwa, Zhenyi Ma

Publication number: 20180000446Abstract: A target biopsy system employing an ultrasound probe (20), a target biopsy needle (30) and a ultrasound guide controller (44). In operation, the ultrasound probe (20) projects an ultrasound plane intersecting an anatomical region (e.g. a liver). The target biopsy needle (30) include two or more ultrasound receivers (31) for sensing the ultrasound plane as the target biopsy needle (30) is inserted into the anatomical region. In response to the ultrasound receiver(s) (31) sensing the ultrasound plane, the ultrasound guide controller (44) predicts a biopsy trajectory of the target biopsy needle (30) within the anatomical region relative to the ultrasound plane. The prediction indicates the biopsy trajectory is either within the ultrasound plane (i.e., an in-plane biopsy trajectory) or outside of the ultrasound plane (i.e., an out-of-plane biopsy trajectory).Type: ApplicationFiled: December 10, 2015Publication date: January 4, 2018Inventors: HUANXIANG LU, JUNBO LI, FRANCOIS GUY GERARD MARIE VIGNON, AMEET KUMAR JAIN, YING WU

Publication number: 20180000447Abstract: An ultrasound measuring device includes: a support bearing two ultrasound probes movable relative to each other by slide link, each of the two probes being movable relative to the support by ball-joint link, wherein the probes are capable of simultaneously acquiring two ultrasound images. The device includes a first set of measuring elements to measure a relative positioning of the probes, including one travel sensor and at least two orientation sensors. The device includes a second set of measuring elements to measure a positioning of the device relative to a reference plane, including at least one orientation sensor. The device localizes at least one point of interest on each of the two ultrasound images, and processes data coming from the first and second measuring elements, delivering a relative spatial position of the points of interest located in the images.Type: ApplicationFiled: December 17, 2015Publication date: January 4, 2018Inventors: Eric Stindel, Manuel Urvoy, Guillaume Dardenne, Julien Leboucher, Shaban Almouahed

Publication number: 20180000448Abstract: An interposer with a spring on a surface of the interposer is disclosed. The spring may apply a force to a surface of a component adjacent to the interposer. The interposer may be secured to the surface by a fastener. The fastener may be offset from the center of the interposer. The fastener may be a fulcrum of a lever including the interposer and the spring. The spring may cause a portion of the interposer on the other side of the fastener from the spring to apply an increased amount of pressure to the surface to which the interposer is secured. A transesophageal exam ultrasound probe including an interposer is disclosed.Type: ApplicationFiled: December 20, 2015Publication date: January 4, 2018Inventor: DINO FRANCESCO CUSCUNA
