Abstract
A method and apparatus are disclosed for a system that maps the proximal and distal ablation subzones and their respective margins using the tools that are used to access the ablation target wherein the tools have markings to indicate which probe and balloon kyphoplasty (BKP) system or vertebroplasty (VP) system to use. Examples of access tools comprise introducers, stylets, and bone drills. In some embodiments of the system, the probe has a marking indicating which BKP or VP system to use.
Claims20
A method for performing ablation comprising:
- providing a system that comprises
- a cannula having a proximal end and a distal end;
- a stylet maneuverable within the cannula and having a proximal end and a distal end, wherein the distal end protrude beyond the distal end of the cannula;
- at least one ablation probe;
- and
- a drill having a proximal portion with one or more markings and a distal portion which extends beyond the distal end of the cannula;
- using the at least one ablation probe to form the ablation zone substantially between the proximal and distal subzones.
A method for performing ablation and delivering cement comprising:
- providing a system that comprises
- a cannula having a proximal and distal end,
- a stylet maneuverable within the cannula and having a proximal and distal end, wherein the distal end protrudes beyond the distal end of the cannula,
- at least one ablation probe,
- a drill having a proximal portion with a marking and a distal portion which extends beyond the distal end of the cannula,
- an inflatable bone tamp, and
- cement;
- using the at least one ablation probe to form an ablation zone having a volume and having proximal and distal subzones, wherein a portion of the proximal subzone is adjacent to the distal end of the stylet;
- manipulating the drill such that the distal portion of the drill is adjacent to the distal subzone;
- and
- delivering a volume of cement less than the volume of the ablation zone into a cement injection zone, a portion of which at least partially overlaps the ablation zone.
A method for performing ablation and delivering cement comprising:
- providing a kit comprising the following components:
- at least one cannula having a proximal and distal portion;
- at least one stylet maneuverable within the at least one cannula and having a proximal and distal portion, wherein the distal portion protrudes beyond the distal portion of the at least one cannula;
- at least one ablation probe having a proximal portion and a distal portion;
- at least one drill having a proximal portion and a distal portion which extends beyond the distal portion of the at least one cannula;
- at least one inflatable bone tamp;
- and
- cement;
- and wherein each component has a marking of a certain identity on its proximal portion and the marking of each component has the same identity;
- using the at least one ablation probe to form an ablation zone having proximal and distal subzones, wherein a portion of the proximal subzone is adjacent to the distal end of the at least one stylet;
- manipulating the at least one drill such that the distal portion of the at least one drill is adjacent to the distal subzone.
