STEERABLE CURVABLE VERTEBROPLASTY DRILL
First Claim
1. A steerable vertebroplasty drill, comprising:
- an elongate, tubular body, having a proximal end, a distal end, and a central lumen extending therethrough;
a deflectable zone on the distal end of the tubular body, deflectable through an angular range;
a handle on the proximal end of the tubular body; and
a deflection control on the handle;
a drill control on the handle;
a drive shaft within the elongate tubular body having a proximal end and a distal end;
a drive bushing configured to rotate the drive shaft upon rotation of the drive bushing;
a boring element on the distal end of the device for creating a cavity within bone,wherein the boring element is operably connected to the distal end of the drive shaft,wherein the drive shaft is configured to move axially within the tubular body with respect to the drive bushing when the deflectable zone deflects through an angular range.

Abstract
Disclosed herein is a steerable, curvable drill that can be used for various applications including vertebroplasty. The drill can include an elongate, tubular body, having a proximal end, a distal end, and a central lumen extending therethrough; a deflectable zone on the distal end of the tubular body, deflectable through an angular range; a handle on the proximal end of the tubular body; and a deflection control on the handle; a drill control on the handle; a drive shaft within the elongate tubular body having a proximal end and a distal end; and a boring element on the distal end of the device for creating a cavity within bone. The boring element can be operably connected to the distal end of the drive shaft, The drive shaft can be configured to move axially within the tubular body when the deflectable zone deflects through an angular range. Systems and methods involving the drill are also disclosed.

9. A method of treating a bone, comprising:
-
creating a pedicular access channel in a pedicle to access the interior of a vertebral body; inserting an introducer cannula into the pedicle; inserting a steerable drill through the introducer cannula into the interior of a vertebral body; drilling through cancellous bone in the interior of a vertebral body to create or enlarge a cavity within the interior of the vertebral body; inserting a steerable injection needle through the introducer cannula into the interior of the vertebral body, the steerable injection needle having a proximal end and a distal end, the distal end having a first configuration substantially coaxial with a long axis of the proximal end; rotating a control to deflect the distal end of the steerable injection needle to a second configuration that is not substantially coaxial with the long axis of the proximal end; and flowing bone cement through the steerable injection needle into the interior of the vertebral body.

10. A kit for performing vertebroplasty, comprising:
-
a steerable injection needle with a proximal portion, elongate shaft, and a distal portion, the distal portion movable from a first substantially straight configuration to a second configuration not substantially coaxial with the proximal portion; a cement dispensing pump comprising a first cartridge housing configured to house a cartridge containing two separate bone cement components; and a mixing nozzle for mixing the first bone cement component and second bone cement component material into a bone cement composite; and a steerable bone drill for creating or enlarging a cavity within the interior of the vertebral body.
