Maipu Regenerative Medical Technology has designed the world’s first 3D Printed dura mater products to be utilized in brain surgeries.
The human brain is protected by a thin layer of tissue called the Dura mater, which is divided into two layers – superficial and meningeal layer. During a brain surgery, these layers are cut open to access the brain. After the completion of a surgery, the protective membranes must be replaced and this process is called a Suture and Onlay procedure.
The 3D printed dura mater products allow surgeons to implement a new method to recover the part of the brain that has undergone a surgical procedure. Once these products are applied, it becomes absorbed by the body over time.
Inventor of the 3d printed dura mater products Yuan Yuyu, who has continued to build 3D printed bio products since 2009 explained “To put it simply, ReDura provides the structure in which cells and tissues can grow. After a period of approximately two months, the meningeal tissue has grown and the ReDura begins to slowly dissolve into two toxin-free components: water and carbon dioxide. After the tissue is fully dissolved and absorbed, there is no foreign material left in place but instead it has been replaced by naturally regenerated dura tissue.”
Yuyu implemented bioprinting technologies instead of the traditional 3d printing technology to use printable water based gel which stimulates collagen structures in the human body.
Yuyu’s products have already been used by hospitals and organizations globally. Xu Tao, Chief Technology Officer and Professor at Tsinghua University explained, “In March of 2011, the product received CE certification in the European Union. Since then, it has been exported to dozens of counties in Europe and to the United States and is being used in hospitals such as the world-renowned Cambridge University. To date, it has been used in over 10,000 patients without a single report of adverse reactions.”
