在医学发明和当地文化的交叉路口，儿科心脏病医生FranzFreudenthal从玻利维亚纺织技术中获得灵感，在全世界进行着一项伟大事业——修复儿童心脏。“我们这个时代最复杂的问题，”他说，“可以用简便的技术解决，只要我们敢于梦想。”他是用什么样的方法治愈那些患先天性心脏病的儿童的呢？让我们跟着他的演讲一起去看看吧~Franz一开始便语重心长地告诉我们：“The most complex problems in our time can be solved with simple techniques， if we are able to dream.”“我们这个时代最复杂的问题可以用简便的技术解决，只要我们敢于梦想。” 儿时的教育奠定了他一生的事业As a child， I discovered that creativity is the key to cross from dreams to reality.小时候，我发现创造力是实现梦想到现实的跨越的关键。 I learned this from my grandmother， Dr. Ruth Tichauer， a Jewish refugee that settled in the heart of the Andes. That is how I grew up: encouraged to see beyond any limitation. So part of my education included helping her in remote， indigenous communities. I cherish those memories， because they helped me to understand life outside the city， a life with a lot of possibilities， without barriers， as language or culture.我的祖母Ruth Tichauer博士是一位居住在安第斯山脉腹地的犹太难民，我从她那里学到了这一点。我是这样长大的：总是被鼓励着让视野超越极限。在偏远地区、当地社区给她（行医）当助手，也成了我从小接受的教育的一部分。我珍惜这些记忆，因为它们帮助我去理解城市以外的生活，一种不管是语言或文化都充满无限可能、没有阻碍的生活。 In the coming years， I became a medical student. One of every hundred children born worldwide has some kind of heart disease. There's a part of this problem I think I can solve -- the part of this problem I have spent my life working on.在接下来的日子里，我成为了一名医科学生。在这个世界上，每100个孩子就有1个孩子患有某种心脏病。我觉得我能够解决一部分这样的问题，并用我的一生去实现。 一类特定心脏病——愈合不完全If it doesn't close， the baby has a hole in the heart. It is caused by prematurity and genetic conditions. But what we know today is that a lack of oxygen is also one of the causes.如果愈合不完全，幼儿的心脏内会出现一个孔。早熟和基因问题都会造成这种孔洞，但现在我们还知道，缺氧也会造成这个状况。 As you can see in the chart， the frequency of this kind of hole dramatically increases with altitude.从图表可以看出，随着海拔的增加，心脏孔洞出现的频率呈戏剧性地增长。When you look at patients with this condition， they seem desperate to breathe. To close the hole， major surgery used to be the only solution.当你看到患者有这样的症状，他们似乎呼吸都极度困难。为了封堵这样的孔洞，开放性手术一直是唯一的方法。 灵感初现One night， my friend Malte， were camping in the Amazon region. The only thing that would not burn in the fire was a green avocado branch. Then came a moment of inspiration.So we used the branch as a mold for our first invention. The holes in children's hearts can be closed with it. A coil is a piece of wire wrapped onto itself.一天晚上，我和我朋友Malte在亚马逊地区露营，在火里唯一不会燃烧的是鳄梨的树枝。然后灵感就这样一闪而现。我们用树枝作了第一个发明的模型。孩子心脏上孔洞可以用它来“闭合”，通过一根盘管在其自身上盘绕。 With my wife and partner， Dr. Alexandra Heath， we started to see patients. After successfully treating patients with our coil， we felt really enthusiastic.在我妻子和伙伴Alexandra Heath的帮助下，我们开始治疗病人。当病人被我们的盘管成功治愈后，我们会感到非常鼓舞。 The first coil could successfully treat only half of the patients in Bolivia. The search started again. We went back to the drawing board.第一根盘管只治愈了玻利维亚一半的病人。新一轮的寻找之旅开始了，我们又回到了画板上。 灵感再现到问题的完美解决After many trials， and with the help of my grandmother's indigenous friends in the mountains， we obtained a new device. For centuries， indigenous women told stories by weaving complex patterns on looms， and an unexpected skill helped us for the new device. We take this traditional method of weaving and make a design made by a smart material that records shape.很多实验之后，我祖母在当地的朋友帮助我们获得了一种新装置。几个世纪以来，当地的妇女用纺织机纺织复杂的图案来诉说故事，所以，我们在这种意想不到的技能的帮助下，获得了新的装置：我们将具有记忆功能材料用传统织布技术加以设计。 As you can see， the device enters the body through the natural channels. Doctors have only to close the catheter through the hole. Our device expands， places itself and closes the hole. We have this beautiful delivery system that is so simple to use because it works by itself. No open surgery was necessary.如你所见，这个装置从人体自然的管道进入，医生只需用通过管道进行封堵。我们的装置扩张之后，它自己将放置在缺口上。从那以后，我们拥有了这个美妙的操作系统，它易行简单，不再需要任何开放性手术。 We are in many countries now， but we need to be everywhere. This whole thing began with one impossible idea as will continue it， really: No child is left behind.我们现在已经在很多国家，但是我们必须遍布世界各地，这一切都因这样一个简单而且会一直奋斗的想法，那就是：一个孩子都不能被落下。 （图为治愈后的幼儿） 是啊！“我们这个时代最复杂的问题可以用简便的技术解决，只要我们敢于梦想。”利用我们所学知识再加上一颗热忱的心，在某个领域奉献自己，相信世界会一天比一天更美好！文案：聂泽锋审校：彭睿陈志红排版：杨涛
