简要总结
The ChordArt System is a novel catheter based technology for mitral chordal replacement that enables controlled implantation of artificial mitral chords to treat mitral regurgitation with a minimally invasive approach. The implant is designed to allow transfemoral antegrade implantation.
详细描述
ChordArt utilizes a minimally invasive catheter based approach by which multiple artificial chordae are precisely positioned into the papillary muscle and then secured to the pathological leaflet.
