Devices for cardiac valve repair

摘要

The utility model discloses a device for replacing chordae tendineae, comprising a flexible patch and a proximal anchor-shaped object of a lobule connector, wherein the flexible patch is fixed on the partial upper surface of a flail lobule through the lobule connector comprising an extensible element pair mutually connected via a central connecting rod. The device further comprises a distal anchor-shaped object extended to and fixed on an end-joining point in a heart; and a flexible Tethered cord connected to the proximal and distal anchor-shaped objects and tensioned between the proximal and distal anchor-shaped objects. The procedures described herein can be performed with interventional tools, guides and supporting catheters and other equipment introduced to the heart chambers from the patient's arterial or venous vasculature remote from the heart. The interventional tools and other equipment may be introduced percutaneously or may be introduced via a surgical cut down, and then advanced from the remote access site through the vasculature until they reach the heart.
