Since 1992, the Garson Medical Stent Research Institute has been exploring and developing esophageal, tracheal, biliary and prostatic Ni-Ti alloy medical stents, being a pioneer in China to apply to clinic. The stents patents come to uncovered, covered and anti-reflux (Patent No. ZL 95 240960. 7, ZL 97 2 35638. X). Evaluated by notable experts, the stent were granted to be the international level properties as the Health Daily reported on January 1, 1997. Meanwhile the esophageal stent, biliary stent, tracheal stent and prostatic stent have been respectively obtained registration certificate from National Committee for Medical Control. At the beginning of new millennium, the Garson Stents were authorized ISO9001 Quality System and Certificate of Assessment-EC, and won good reputation from the market covering Europe, South America, Middle East, etc.
The Garson Stent adopt the alloy material which was refined by 6 processes and the quality reaches the U. S. A memory alloy standard. The macromolecule biomembrane adopts the man-made vascular material, which feature corrosin resistance, alkali resistance, pepsin hydrolysis resistance, excellent biological compatibility, anti-bending, tender sastentation, etc.
