High polymer gel and vascular lesion embolizing material comprising the same |
摘要 |
The improved vascular lesion embolizing material comprises a high-polymer gel capable of absorbing water in an amount of 10 ml/g and more. The high-polymer gel is preferably such as is produced by first permitting a solution containing a water-soluble high polymer to be precipitated in a solution containing polyvalent cation, said high polymer having a plurality of monovalent anionic functional groups, and then immersing the resulting precipitate in a salt solution. The material will swell upon contact with blood and is capable of embolizing a focal lesion in a blood vessel without causing any adverse effects on the living body. The swell time can be shortened if the embolizing material is made of a high-polymer gel that has been treated with a salt solution after precipitation.
