New progress of nickel titanium tube

Nickel titanium tubes have recently made headlines for several major advances.

In February 2024, the research and development and industrialization project of high-precision implantable nickel-titanium tube for medical use was signed in Zhangpu, Kunshan. The project, a collaboration between Kangtai Medical Technology (Suzhou) Co., Ltd. and Southeast University, aims to address the substitution challenges of medical nickel-titanium alloy tubes in China. The project, with an investment of 100 million yuan, is expected to be put into production in April 2024, with a cumulative output value of more than 500 million yuan within five years, and plans to be listed. The project will not only contribute to the development of Zhangpu's biopharmaceutical industry, but also attract more related enterprises and strengthen the local industrial cluster.

In the field of neuroscience, nickel-titanium based devices also show promise. For example, Stentrode, derived from a dilatant Nitinol stent, has achieved intravascular electrocorticogram (ECoG) recording and stimulation in the superior sagittal sinus of sheep and has advanced to clinical trials for motor neuroprosthetics in severely paralyzed human patients.

Another area of focus is the use of nickel titanium tubes in medical devices, such as birth control implants. In 2016, the U.S. Food and Drug Administration (FDA) stepped up its warning against Essure after thousands of women complained of chronic pain, bleeding and other health problems associated with nickel-titanium implants. Although the FDA did not remove the device from the market, it asked the manufacturer, Bayer, to conduct a study to further assess its risks.

MIT researchers have developed a new drug delivery system that uses thin, flexible wires made from Nitinol to treat tuberculosis. The wire, which is loaded with antibiotics and inserted into a patient's stomach through a nasogastric tube, slowly releases the drug over a month, reducing the burden of daily medication. This innovation can improve treatment adherence and has the potential to reduce healthcare costs, especially for patients in areas with limited medical facilities.

In terms of production and quality management, companies have emphasized that nickel-titanium tubes must go through strict inspection procedures before entering the market.

In addition, the application of laser cutting technology in the processing of Nitinol stent has greatly reduced costs, making life-saving medical equipment cheaper and more accessible.

In conclusion, the latest news on nickel titanium tubes highlights their importance in various fields, from biomedical applications to drug delivery systems, as well as the ongoing efforts to improve their performance, quality and accessibility.
