Claim:
1. A method of restoring bone, comprising: identifying a cavity within an interior of a vertebra bone; inserting a first resorbable balloon through an access passageway to the interior of the vertebra bone and into the cavity; inserting a second resorbable balloon through the access passageway to the interior of the vertebra bone and into the cavity such that the second resorbable balloon is nested within the first resorbable balloon, wherein the inserting of the second resorbable balloon occurs after the inserting of the first resorbable balloon; injecting a therapeutic agent into at least one of the first and second resorbable balloons; wherein the first and second resorbable balloons remain in the cavity for an amount of time until the first and second resorbable balloons degrade, thereby allowing the therapeutic agent to be delivered into contact with an interior surface of the cavity.
