| Research Abstract |
We developed an artificial papillary muscle by using covalent-type Ni-Ti anisotropic shape memory fibres. We could achieve the development of a tissue-rubber hybrid left ventricular model including native heart valves. Subsequently we could investigate optimised mechanical interactions between mitral valve leaflets and the left ventricle with the artificial papillary muscle reducing mitral valve regurgitation.
