Publication number: 20240035590Abstract: In a segmented ball valve for low noise and anti-cavitation applications, a replaceable cartridge is fixed inside and retained by stem and end post. The segment has a machined cylindrical bore with a slide-fit noise cartridge, enabling field replaceability with minor effort & without need of welding or fasteners. The replaceable cartridge also enables use of a fully cylindrical cartridge with greater pressure reduction stages compared to welded-on noise plates on the segment. The segment has a flattened front face resulting in lower Fd enabled by dual flow path in lower openings values thereby attaining higher noise attenuation where the cartridge is not required. The curved plates of the low noise and anti-cavitation cartridge enable: expanding flow resulting in non-impinging jet streams thereby achieving higher noise attenuation in one direction; and converging flow in the opposite direction resulting in reduction of flow energy, and the potential for cavitation for liquids.Type: ApplicationFiled: July 25, 2023Publication date: February 1, 2024Inventors: Mathew Varghese, Pramod B.

Publication number: 20210275301Abstract: The present invention provides a prosthetic heart valve device with improved fit and/or apposition between the device frame and left atrial tissue and/or the device base and the annular tissue of the left atrium to improve shifting of the implanted device and/or mitigate paravalvular leakage. The improved fit and/or apposition arises in various embodiments by providing or allowing an asymmetrical frame and/or frame base and/or providing a lower lip to aid in conforming to the asymmetrical shape of the atrium and/or ensure firm positioning therein. An additional benefit of these arrangement(s) is mitigation of paravalvular leakage as a result of improved fit and seal. In certain embodiments, the asymmetry of the frame assists with delivery of the device into the atrium.Type: ApplicationFiled: February 1, 2021Publication date: September 9, 2021Inventors: Saravana B.
