Embolic Microspheres bụ obere hydrogel hydrogel a na-apịachi apịachi nwere ọdịdị nkịtị, elu dị larịị, na nha nhazi, nke a na-emepụta site na mgbanwe kemịkalụ na ihe polyvinyl alcohol (PVA). Embolic Microspheres nwere macromer sitere na polyvinyl alcohol (PVA), ha bụ hydrophilic, a naghị anabata ya, ha dịkwa n'ọtụtụ nha. Ngwọta nchekwa bụ 0.9% sodium chloride solution. Mmiri dị na obere polymers nke a na-eme ka ọ dị ọcha bụ 91% ~ 94%. Microspheres nwere ike ịnagide mkpakọ nke 30%.
