  • Device and method for real-time lesion estimation during ablation
    Patent number: 9730750
    Abstract: Disclosed herein are ablation systems and methods for providing feedback on lesion formation in real-time. The methods and systems assess absorptivity of tissue based on a degree of electric coupling or contact between an ablation electrode and the tissue. The absorptivity can then be used, along with other information, including, power levels and activation times, to provide real-time feedback on the lesions being created. Feedback may be provided, for example, in the form of estimated lesion volumes and other lesion characteristics. The methods and systems can provide estimated treatment times to achieve a desired lesion characteristic for a given degree of contact, as well as depth of a lesion being created. The degree of contact may be measured using different techniques, including the phase angle techniques and a coupling index.

  • Method and Device for Protecting Video Digital Copyrights
    Publication number: 20170127151
    Abstract: Embodiments of the present disclosure disclose an electronic device, method, system, and computer-readable medium for protecting video digital copyrights, comprising: acquiring a user identity requesting to play a video and a video play identity, using the user identity as a two-dimensional code to generate a parameter; generating a two-dimensional code, which is decoded to obtain the user identity; and overlapping the two-dimensional code on a designated video frame that plays the video play identity. In particular, the two-dimensional code is generated through the user identity, and the two-dimensional code is overlapped on the video frame. When the video is bootlegged, a bootlegged frame will contain the two-dimensional code; therefore, the user identity is obtained from the two-dimensional code conveniently, thus ascertaining a bootlegging source.

  • Irrigated ablation catheter system with pulsatile flow to prevent thrombus
    Patent number: 9622814
    Abstract: The invention relates to an ablation catheter which controls the temperature and reduces the coagulation of biological fluids on an electrode of a catheter, prevents the impedance rise of tissue in contact with the electrode, and maximizes the potential energy transfer to the tissue, thereby allowing an increase in the lesion size produced by the ablation. The electrode includes passages positioned to allow saline flow out of an inner cavity of the electrode. This fluid flow is pulsatile to increase turbulence, reducing areas of stagnant flow, and produces a desired cooling effect.
