Abstract: 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.

Abstract: A drug-delivery device includes a body configured for attachment to a handle of an ablation device, a shaft portion defining a passageway therein, and a delivery lumen to provide for drug delivery to tissue. The body includes a proximal portion, a distal portion, and a contoured portion disposed therebetween. The contoured portion is configured for engagement with a contoured portion of the handle of the ablation device. The shaft portion includes a proximal end and a distal end. The proximal end of the shaft engages with an opening defined in the distal end of the body. The passageway of the shaft portion is configured to receive the delivery lumen slideably moveably therein. The delivery lumen includes a proximal portion and a distal portion. The drug-delivery device also includes a knob member coupled to the proximal portion of the delivery lumen.
