The cooperation with some healthcare professional on researches aimed to jointly develop intracranial stent graft and realize the commercialization.
The cerebrovascular diseases are characterized by high treatment risk and high fatality rate. With the development of interventional therapy and surgery, it is possible to have timely and effective treatment of most cerebrovascular diseases. However, it is still difficult for a number of patients suffering cerebrovascular diseases to obtain satisfactory treatment because of the particularity of their lesions and the restrictions of therapeutic materials. In 1996, a medical expert put forward the initial concept of treating patients suffering internal carotid artery defect with stent grafts. But it was difficult to realize the concept given that the challenges arising from the narrow and tortuous cerebrovascular lumens were beyond the domestic scientific and technological capacities at that time. Though the development of this new type of cerebrovascular stent graft has its special use, its application is limited and the market is small. Few companies in the world were willing to develop such products because of the high cost of research and development, long period and delicate manufacturing process. In 2004, MicroPort® officially organized a team to cooperate with the healthcare professional to develop the Cerebrovascular Stent Graft.
