Summit owns natural tissue treatment techniques with worldwide patent protection. It has a contingent of first-class scientific experts, as well as experienced management and sales teams. Using advanced techniques, Summit is engaged in the development of surgical implants that will fill the gaps in the related categories. Summit has successfully researched and developed a biological dural graft, NormalGen, which has been on the market since SFDA approval on June 30, 2006. By using techniques such as the patented epoxy cross-linking fixation of animal tissue, our independently developed antigen reduction technique, protein modification enhancing mechanical properties, surface activation of enrichment growth factors, and surface modification of coupled anti coagulation, we developed a large number of natural biomaterials with animal tissue as the raw material. In cooperation with medical experts, we conducted a series of research experiments in organ reconstruction. At present, the products being researched and developed are: a biological surgical patch, artificial biological vascular grafts , a biological esophagus (carrier for reconstruction of the esophagus in situ), biological ligaments, biological nerve guides, biological adhesion preventing membrane, biological bone graft and cartilage, biological ureter and urethra, etc.
