Claim 12:
13. A method for creating a space in a body structure and injecting a filler material into the space, the method comprising:
inserting a distal end portion of a needle-mounted balloon system into the body structure, wherein the needle-mounted balloon system comprises;
a cannula comprising:
a handle;
a cannula hub coupled within a housing of the handle;
a cannula tube portion extending distally from the cannula hub, the cannula tube portion defining a lumen therethrough; and
an expandable member coupled to the cannula tube portion, the expandable member being reconfigurable between a diametrically contracted configuration and a diametrically expanded configuration; and

a stylet that is engageable with the cannula, the stylet comprising:
a stylet hub detachably coupled to the handle; and
a stylet needle extending distally from the stylet hub, wherein the stylet needle is slideably disposable within the lumen of the cannula tube portion, wherein, when the stylet is fully engaged with the cannula, a sharp distal tip portion of the stylet needle extends distally beyond the cannula tube portion, and wherein the expandable member is expandable when the stylet is engaged with the cannula;

reconfiguring the expandable member from the diametrically contracted configuration to the diametrically expanded configuration while the expandable member is in the body structure;
reconfiguring the expandable member from the diametrically expanded configuration to the diametrically contracted configuration such that an open space remains in the body structure; and
injecting the filler material into the open space.
