Systems for augmenting of a vertebral body by providing for relative movement of a deformable conduit

A system for augmenting a vertebral body, the system comprising:

• an access cannula;
• a steerable assembly comprising a steering instrument;
• a deformable conduit assembly comprising one or more arms, and a deformable conduit coupled to the one or more arms and within which the steering instrument is removably disposed, 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 access cannula, and an expandable structure configured to be directed within or through the deformable conduit,
• wherein the deformable conduit assembly further comprises a hub defining one or more guiding slots though which the one or more arms are slidably positioned to facilitate exposing of the expandable structure.

A system for augmenting a vertebral body, the system comprising:

• an access cannula defining a lumen;
• a steerable assembly comprising a steering instrument;
• a deformable conduit assembly comprising:
• a deformable conduit within which the steering instrument is removably disposed, wherein the deformable conduit is configured to be curved by the steering instrument;
• a hub defining an opening configured to be coaxially arranged with the lumen of the access cannula in a fixed axial relationship;
• and
• an axial controller coupled to a proximal end of the deformable conduit,
• wherein the axial controller is configured to receive an input from a user to move the deformable conduit relative to the hub and the access cannula.
