Patent ID: 7993343

Claim:
An extractable device, comprising: a flexible container having a proximal injection port configured to receive a solidifiable medicinal filling, and a previously created releasably closable distal opening configured to selectively allow delivery of the filling into a vertebral body outside of the container; and at least one releasable thread configured to releasably close the distal opening to contain the filling within the container prior to solidification, and configured to allow the distal opening to reopen without permanently severing the flexible container to enable the delivery of the filling into the vertebral body outside of the container after at least partial solidification; the flexible container having a first configuration, a second configuration and a third configuration, when the flexible container is in the second configuration, the flexible container is substantially tubular, when the flexible container is in the third configuration, the distal opening of the flexible container is open and the flexible container is disposed at least partially within the vertebral body, the proximal injection port having a substantially constant size when the flexible container is in the first configuration, the second configuration, and the third configuration.
