Publication number: 20240122484Abstract: Exemplified methods and systems facilitate presentation of data derived from measurements of the heart in a non-invasive procedure (e.g., via phase space tomography analysis). In particular, the exemplified methods and systems facilitate presentation of such measurements in a graphical user interface, or “GUI” (e.g., associated with a healthcare provider web portal to be used by physicians, researchers, or patients, and etc.) and/or in a report for diagnosis of heart pathologies and disease. The presentation facilitates a unified and intuitive visualization that includes three-dimensional visualizations and two-dimensional visualizations that are concurrently presented within a single interactive interface and/or report.Type: ApplicationFiled: October 23, 2023Publication date: April 18, 2024Inventors: Ian Shadforth, Meng Lei, Timothy Burton, Don Crawford, Sunny Gupta, Paul Douglas Souza, Cody James Wackerman, Andrew Hugh Dubberly

Patent number: 11395618Abstract: The present disclosure facilitates capture of biosignal such as biopotential signals in microvolts, or sub-microvolts, resolutions that are at, or significantly below, the noise-floor of conventional electrocardiographic and biosignal acquisition instruments. In some embodiments, the exemplified system disclosed herein facilitates the acquisition and recording of wide-band phase gradient signals (e.g., wide-band cardiac phase gradient signals, wide-band cerebral phase gradient signals) that are simultaneously sampled, in some embodiments, having a temporal skew less than about 1 ?s, and in other embodiments, having a temporal skew not more than about 10 femtoseconds. Notably, the exemplified system minimizes non-linear distortions (e.g., those that can be introduced via certain filters) in the acquired wide-band phase gradient signal so as to not affect the information therein.Type: GrantFiled: January 27, 2020Date of Patent: July 26, 2022Assignee: Analytics For Life Inc.Inventors: Sunny Gupta, Don Crawford, Timothy William Fawcett Burton, Shyamlal Ramchandani, Kristine Canavan

Patent number: 11369384Abstract: Methods, devices and systems are described for treating venous insufficiency in which the vein is compressed at least partially along a treatment zone. A system can be provided including an injection device, such as a glue gun, that is operably connected to a delivery catheter that can be advanced across a treatment zone in the vein. The delivery catheter can be used to deliver one, two, or more boluses of media (e.g., cyanoacrylate) to occlude the vein along different spaced-apart sections of the treatment zone. External compression can also be applied to the vein by a compression element, such as a hand or multifunctional ultrasound transducer, to occlude portions of the vein along the treatment zone prior to or during the introduction of the boluses of media.Type: GrantFiled: May 27, 2020Date of Patent: June 28, 2022Assignee: COVIDIEN LPInventors: Rodney D. Raabe, Jack Chu, Don Crawford, Jan R. Lau, Zhenyu Zuo
