摘要： A method of repairing an inner vessel wall includes the step of inserting at least a portion of a microwave ablation device into a vessel. The microwave ablation device includes an inner conductor disposed within an outer conductor and defines a longitudinal axis. The method also includes the steps of inserting a repairing sealant into the vessel such that the repairing sealant is disposed between an inner vessel wall and the outer conductor and expanding at least a portion of the outer conductor relative to the longitudinal axis to force at least a portion of the repairing sealant into the inner vessel wall. The method also includes the step of delivering energy to at least one of the inner conductor and the outer conductor to activate the repairing sealant to repair the inner vessel wall.
