  • Publication number: 20250057646
    Abstract: A hybrid heart valve prosthesis that can be quickly and easily implanted during a surgical procedure is provided. The hybrid heart valve includes a substantially non-expandable, non-compressible prosthetic valve member having a peripheral sealing ring and an expandable stent frame projecting from an inflow end, thereby enabling attachment to the annulus without sutures. The stent frame may be plastically-expandable and may have a thin fabric layer covering its entirety as well as secondary sealing structures around its periphery to prevent paravalvular leaking. Other sealing solutions include interactive steps at the time of valve implant to establish seals around the stent and especially between the stent and the sealing ring of the valve member.

  • Patent number: 7706744
    Abstract: A modular wireless repeater typically deployed with a roof-mounted tower-signal antenna and a base unit with a base unit antenna located within the building, to which the tower-signal antenna and the base unit are connected by the user or a satellite TV installer using a 75? coaxial cable. The system allows a customer to purchase a unit for all wireless service providers in a given frequency band, such as Cellular, PCS, GSM900, or DCS, etc., and then add on modules for additional types of service that the customer may desire in the future. The system also detects and prevents low-level oscillations. The wireless repeater also performs intelligent power control allowing it to function properly with near and far base unit antennas as well as near and far mobile stations.
