Atelocollagen coil development which was New device in the noxious and abnormal blood vessel embolectomy was planned,and for the impossible,the coil manufacture newly drafted the development of liquid vascular occlusion plug using the collagen solution at present.The atelocollagen implant,ACI of KOUKEN CO.LTD.changes over 37'C from the liquid to the elasticity gel,and it has been used as lachrymal gland closure plug and skin collapse filler practically.The delivery system which stored ACI to abnormal blood vessel was amended in the system for injecting direct ACI in the catheter diameter 5Fr.the above tip hole style.For In vitro experiment and plan correction and design,the animal experiment start by the rabbit was drastically retarded.In the future,the animal experiment will be advanced in as planned in the beginning.
