Development of an artificial papillary muscle recovering left ventricular functions

利用共价型镍钛各向异性形状记忆纤维研制了一种人工乳头肌。我们可以实现包括天然心脏瓣膜的组织-橡胶混合左心室模型的开发。随后，我们可以研究二尖瓣瓣叶和左心室之间的优化机械相互作用，人工乳头肌减少二尖瓣返流。

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.
