Recently, sichuan university, national biomedical materials engineering technology research center director professor Wang Yunbing team, Shanghai shape memory alloy material co., LTD., and the Chinese academy of medical sciences professor fuwai hospital Pan Xiangbin team cooperation, for nine years of research and development of the whole degradation closure system getting listed on the state drug administration approved formally,It marks China’s breakthrough in the field of fully degradable plugging device into the world’s leading ranks.China is one of the countries with high incidence of congenital heart disease. Interventional occlusion is one of the common methods for the treatment of congenital heart disease.With a thoracotomy, doctors perform a surgical correction or patch it with a patch.However, implanted occlusions are usually made of metal material, and there is a risk of complications such as heart block due to wear and compression between the growth of the autologous tissue and the fixation of the metal material.The development of absorbable sealing device is the key to solve the above problems.The fully degradable sealing device system realizes the leap of sealing device from metal material to degradable material. This fully degradable heart sealing device made of medical polymer material can be gradually degraded after completing the repair function of heart defect, and can be safely absorbed by human tissues.The degradation cycle of the product is designed according to the human tissue repair cycle, and the dynamic mechanical support performance of the sealing device is well matched with the tissue repair.While ensuring the success of sealing congenital heart defect, it can be completely degradation after one year, without foreign body residue, and the heart defect part can be completely repaired by autologous tissue, avoiding the long-term complications that may be brought by permanent retention of traditional metal sealing device after implantation, so that patients with congenital heart disease can grow up healthy.Declaration: The copyright of this article belongs to the original author, if there is a source error or infringement of your legitimate rights and interests, you can contact us through the mailbox, we will promptly deal with.Email address:
