Publication number: 20240122704Abstract: Disclosed is a recoverable and self-expanding short-frame valve suitable for aortic valve regurgitation, including a tubular frame and valve leaflets. The tubular frame can contract to a delivery configuration or expand to a use configuration in a radial direction; the tubular frame includes a first portion and a second portion integrally formed and coaxially arranged; a waist portion is formed at the junction of the first portion and the second portion when the tubular frame is in the use configuration; and the second portion is divergently arranged in a direction away from the waist portion. According to the present disclosure, the complete recovery of the valve can be realized without affecting the later coronary intervention.Type: ApplicationFiled: September 21, 2023Publication date: April 18, 2024Inventors: Yang Chen, Yongjian Wu, Qingrong Liu, Jie Zhao, Hongliang Zhang

Publication number: 20240077632Abstract: The present disclosure belongs to the field of geological exploration, and particularly relates to a seismic acquisition system based on a frequency domain expansion MEMS sensor, aiming at solving the problem that vibration frequencies exceed the frequency range of the MEMS sensor due to strong vibrations and cross coupling of multi-frequency signals usually occurring in well logging while drilling. When the MEMS sensor suffers strong vibrations or the MEMS sensor that can be selected cannot ensure that the frequency requirement of a measurement signal is stably met, the frequency domain expander of the present disclosure expands the frequency domain of a detection signal, so that the MEMS sensor can measure strong vibrations and out-of-band frequencies to a certain extent, the application range of the seismic acquisition system is extended, and the anti-mutation capability of the seismic acquisition system is improved.Type: ApplicationFiled: November 23, 2022Publication date: March 7, 2024Applicant: Institute of Geology and Geophysics, Chinese Academy of SciencesInventors: Jing LIU, Zongwei LI, Yongjian ZHOU, Kedu HAN, Changchun YANG
