Publication number: 20190328519Abstract: Prosthetic valves and methods of use of prosthetic valves may be provided. In one implementation, an expandable prosthetic valve may be configured for implantation within a native heart valve. The prosthetic valve may include an expandable outer frame formed at least partially of outer frame struts. The prosthetic valve may also include an inner frame with tissue anchors extending therefrom, the inner frame being formed at least partially of inner frame struts. The struts along the downstream ends of the outer and inner frames may be arranged in undulating configurations to extend between peaks and troughs. A trough of the outer frame may be configured to be situated downstream from a peak of the inner frame.Type: ApplicationFiled: July 10, 2019Publication date: October 31, 2019Applicant: CARDIOVALVE LTD.Inventors: Ilia HARITON, Boaz HARARI

Publication number: 20190328524Abstract: A heart valve prosthesis is proposed, including a housing, at least one leaflet installed within the housing, at least one sensor and/or valve performance monitoring device. The sensor and/or monitoring device is built into the housing and/or leaflet. In an embodiment, the housing and/or leaflet has an oscillating circuit including an inductor coil connected to the sensor and/or monitoring device. One such coil can be built into the housing, and another coil can be built into the leaflet. In another embodiment, one coil can be built into a first leaflet, and another coil can be built into a second leaflet, wherein the sensor and/or monitoring device determines a degree of opening/closing the leaflets by measuring inductive interconnection between the coils, and operation timing characteristics of the valve. In an embodiment, the valve may include an emission sensor disposed within the leaflet and/or housing capable of detecting the valve's open/closed positions.Type: ApplicationFiled: July 17, 2018Publication date: October 31, 2019Inventors: Alexander V. Samkov, Dmitry V. Cherkesov, Anton D. Solodukhi
