Definitions

• the cannula 22a, 22b preferably is made of a surgical grade of stainless steel, but may be made of known equivalent material(s) that are both biocompatible and substantially non-compliant at the expected operating pressures.
• the cannulas 22a, 22b each define a proximal region 40a, 40b, a distal end 42a, 42b, and a lumen 44a, 44b (referenced generally), respectively, to allow various equipment such as the cavity-forming device 20a, 20b, a delivery tube 14, one or more stylets (not shown here, but discussed and illustrated with reference to embodiments of FIGS. 4A-4H below), and/or other elements, to pass therethrough.
• body 60a, 60b is slidably inserted within the corresponding cannula 22a, 22b, with the respective working end 62a, 62b being distally advanced
• a delivery cannula may include a closed distal end terminus and a side-facing opening near the terminus, where the opening is oriented along an outside surface of the curved portion of the delivery cannula near its closed distal end terminus. It may also include proximal-end indicia that show the direction of distal cannula curvature.
• the curvature of the delivery cannula may be configured to correspond to the preset curve of a separate stylet 470, or the stylet 470 may - instead of being constructed as a solid-cross-section stylet - be constructed as a/the precurved delivery cannula as described above.
• the curable material delivery structure labeled with reference number 414 may instead be embodied as a delivery cannula/stylet (such as, for example, an AVAflex® needle/ cannula/ stylet of the type described above).
