1. A system for augmenting a vertebral body, the system comprising:
an access cannula comprising a cannula handle;
a steerable assembly comprising a steering instrument;
a deformable conduit assembly comprising a hub defining an opening, and a deformable conduit within which the steering instrument is removably disposed, wherein the deformable conduit and the steering instrument are configured to be directed through the access cannula, and wherein the deformable conduit is configured to be curved by the steering instrument; and
an expandable member assembly comprising a catheter tube configured to be slidably positioned through the opening of the hub and the cannula handle of the access cannula, and an expandable structure configured to be directed within or through the deformable conduit,
wherein the deformable conduit is configured to be moved proximally relative to the hub and the expandable member assembly to expose the expandable structure.
