A method for forming an embolism within a blood vessel is disclosed. The method includes including: implanting an oxidized cellulose embolization solution into a lumen of a blood vessel to form an embolism within the lumen. The oxidized cellulose is present in an amount from about 10% by weight to 20% by weight of the oxidized cellulose embolization solution. The method also includes adjusting recanalization time of the embolism, which may be adjusted by tailoring a degradation rate of the oxidized cellulose.
