Abstract
A cement delivery needle for use in performing vertebroplasty is provided. In one embodiment, there is provided a cement delivery needle with a sheath and an insert. The sheath has an inlet to receive a bone cement and a tapered outlet for expressing the cement into a vertebral body. The insert is receivably removable within the sheath. The insert also has a tip that is alignable with the outlet, when the insert is inserted into the sheath, to present a continuous edge. When the edge is inserted into a resistant material, an application of force to the needle creates an opening in the material to allow the needle to pass therethrough.
