Delivery of apparatus and methods for vertebrostenting

摘要

The present invention generally is directed toward a spinal fixation system whereby a coupling element allows the physician to selectively lock or unlock either the connection between the coupling element and a fastener, such as to allow for repositioning of the coupling element, or the connection between the coupling element and an elongate rod. The locking or unlocking of these connections may be made independently and as desired by the physician.

主权项

1. A surgical method comprising:
creating a pathway to a vertebral body; forming a curved pathway in the vertebral body using a curved drill; enlarging the curved pathway to form an enlarged cavity in the vertebral body using a reamer; inserting a stent via a stent delivery system into the enlarged cavity, wherein the stent delivery system comprises a sheath extended over the stent, wherein the stent comprises a co-braided structure that is self-expandable and collapsible within the sheath; and removing the sheath from the stent to deploy and expand the stent, wherein the stent expands on its own within the vertebral body without the use of a filler material, and simultaneously moving forward the stent to compensate for any foreshortening of the stent during removal of the sheath.
