意大利索林集團Sorin Group 
一家意大利致力于醫療技術領域的跨國公司，它最近宣布將推出一種在其種類中堪稱革命性的人工心臟瓣膜。一種能不打開胸部或停止心臟而被植入患者的產品。所以簡而言之，或許不必實施外科縫合術。這是一種生物學支持結構的瓣膜，由于它利用了其它的醫療技術大約有十年，其基本概念已經得到完善并經過試驗。很長的孵化期使之能科學地展示其可靠性，現在對之已經不再有疑義了。

Sorin Group is a global company and a leader in the treatment of cardiovascular diseases. The Company develops, manufactures and markets medical technologies for cardiac surgery and for the treatment of cardiac rhythm disorders.
