Abstract
Methods and apparatus for treating bones, including, in one or more embodiments, methods and apparatus for treatment of vertebral fractures that include a containment assembly for cement containment and/or a balloon assembly for maintaining vertebral height. A containment assembly comprising a containment jacket adapted to be deployed inside bone; and a dividing wall that separates the interior of the containment jacket into a proximal region and a distal region, the dividing wall having an opening for providing access to the distal region from the proximal region.
Claims20
A method for treating bone, comprising:
- creating a cavity in the bone;
- placing a containment jacket into the cavity, the containment jacket coupled to an annular member;
- introducing filler material into the containment jacket;
- inserting a cutting device into the annular member, the cutting device including a cutting edge and a pusher rod;
- and
- moving the pusher rod distally into the cutting device to increase a diameter of the cutting edge from a first relaxed diameter to a second expanded diameter such that the cutting edge engages an inner surface of the annular member, thereby detaching the containment jacket from the annular member.
A method for treating bone, comprising:
- creating a cavity in the bone;
- placing a containment jacket into the cavity, the containment jacket coupled to an annular member;
- introducing filler material into the containment jacket;
- inserting a cutting device into the annular member, the cutting device including a cutting edge extending around a face of the cutting device, the face being separated into two halves by a gap;
- and
- inserting a pusher rod distally into the cutting device to increase a diameter of the cutting edge from a first relaxed diameter to a second expanded diameter such that the pusher rod pushes apart the face at the gap, thereby pushing apart the two halves of the cutting edge to engage an inner surface of the annular member, and detaching the containment jacket from the annular member.
A method for treating bone, comprising:
- creating a cavity in the bone;
- placing a containment jacket into the cavity, the containment jacket coupled to an annular member;
- inflating the containment jacket;
- inserting a cutting device into the annular member, the cutting device including a cutting edge extending around a face of the cutting device, the face being separated into two halves by a gap;
- and
- inserting a pusher rod distally into the cutting device to increase a distance between the two halves such that the pusher rod pushes apart the face at the gap, thereby pushing apart the two halves of the cutting edge to engage an inner surface of the annular member, and detaching the containment jacket from the annular member.
