  • Adjustable artificial chordae tendineae fixing assembly and an implanting method thereof
    Patent number: 11331188
    Abstract: An adjustable artificial chordae tendineae fixing assembly includes an occlusion device and an adjusting rod which are both a hollow structure allowing the artificial chordae tendineae to pass through. The occlusion device is configured to be clamped on the interventricular septum. The occlusion device is provided with a switch adjusting device which controls the artificial chordae tendineae to move and to be fixed. The adjusting rod is connected to the occlusion device, and is capable of repeatedly adjusting the switch adjusting device on the occlusion device. The artificial chordae tendineae fixing assembly can fix the artificial chordae tendineae on the interventricular septum, and can also overcome the problem of unsuitable length of the artificial chordae tendineae in most of patients after the procedure due to cardiac changes. The artificial chordae tendineae is retained at the skin puncture point for a short time.
