This unremarkable piece of “wire” is a heart stent. Known for its flexibility and small size, it has saved many patients with coronary heart disease. Heart stents used to be expensive medical supplies, creating a heavy financial burden for patients. Fortunately, with the development of ultrafast laser processing technology, heart stents are now much more affordable.The advantages of ultrafast laser cutting in micro- and nano-level processing of modern medical materials are becoming more apparent. The high precision temp control of TEYU S&A ultrafast laser chiller is also crucial in laser processing, which concerns whether ultrafast laser can emit light stably in picoseconds and femtoseconds. Ultrafast laser will keep breaking even more processing problems of micro and nano materials. So it will be widely used in the future medical device industry.
