Abstract
Methods of creating a curvilinear cavity within a vertebral body or other bony structure and devices that may be used to perform the steps to create the curvilinear cavity. In one embodiment, a method of forming a curvilinear void in bony structure may include the steps of accessing a bony structure with a cannula, inserting a distal end of a drill device through the cannula and into the bony structure, manipulating the distal end of the drill device to create a curvilinear void in the bony structure, enlarging the void by expansion of a balloon element mounted to the drill device, and deflating the balloon element and removing the drill device from the cannula.
Claims20
An apparatus for forming a curvilinear void in bony structure, comprising:
- a curvilinear drilling device, comprising a handle and a flexible drill shaft assembly extending from a distal end of the handle, wherein the flexible drill shaft assembly includes a cutting tip located at a distal end of the flexible drill shaft assembly, a flexible rotatable drive shaft coupled to the tip, and a flexible, moveable and non-rotatable housing, wherein the distal end of the flexible drill shaft assembly includes a plurality of slots configured to allow the distal end to bend;
- and
- a multi-lumen balloon assembly having a hollow shaft and an expandable balloon element mounted on a distal portion of the hollow shaft,
- wherein the curvilinear drilling device is configured to be slidably inserted through the hollow shaft of the multi-lumen balloon assembly, and
- wherein the curvilinear drilling device and the multi-lumen balloon assembly are configured to be positioned within a vertebral body.
An apparatus for forming a curvilinear void in bony structure, comprising:
- a handle assembly;
- a curvilinear drilling device, wherein the drilling device comprises a feedscrew assembly including a feedscrew having a threaded mating with the handle assembly configured to provide rotational and axial driving motion and a key component configured to movably couple the drilling device to the handle assembly to ensure a desired circumferential orientation between the drilling device and the handle assembly, wherein a distal end of the drilling device includes a plurality of slots configured to allow the distal end to bend;
- and
- a multi-lumen balloon assembly having a hollow shaft and an expandable balloon element mounted on a distal portion of the hollow shaft,
- wherein the curvilinear drilling device is configured to be slidably inserted through the hollow shaft of the multi-lumen balloon assembly,
- wherein the drilling device further comprises a flexible drill shaft assembly extending from a distal end of the handle, wherein the flexible drill shaft assembly includes a cutting tip located at a distal end of the flexible drill shaft assembly, a flexible rotatable drive shaft coupled to the tip, and a flexible, moveable and non-rotatable housing, and
- wherein the curvilinear drilling device and the multi-lumen balloon assembly are configured to be positioned within a vertebral body.
