Vertebroplasty leak prevention sleeve and method

摘要

A sleeve for use in inhibiting leakage of bone cement during a vertebroplasty procedure. The sleeve includes a hollow main body portion and a plunger-like shield disposed at the distal end of the main body portion. The main body portion is sized to be fitted over the cannula of a conventional vertebroplasty assembly through which the cement is injected, and the shield is sized to cover the injection hole in the vertebra, thereby inhibiting leakage of injected cement back through the injection hole.
