Abstract
Discectomy or disc preparation system that includes a guide member that is changeable from a deployment configuration for insertion into an intervertebral disc space to a deployed configuration upon being deployed into the intervertebral disc. The system also includes at least one tissue manipulator, such as cutting, scraping and extraction elements, that can be moved or tracked longitudinally along the guide member into and through the intervertebral disc space.
Claims20
An intervertebral disc preparation system for preparing an intervertebral disc space for implantation of a prosthetic device, comprising:
- a guide member having a proximal end portion and a distal end portion, the distal end portion of the guide member changeable from a deployment configuration for insertion into the intervertebral disc space to a deployed configuration within the intervertebral disc space;
- at least one elongated member having a distal end portion and an outer surface, the elongated member adapted to be moveable longitudinally along the guide member;
- and
- at least one tissue manipulator for manipulating tissue within the intervertebral disc space, the tissue manipulator located at the distal end portion of the elongated member and having at least one tissue manipulation surface that is spaced in a radial direction from the outer surface of the elongated member.
A system for the removal of tissue from an intervertebral disc space, comprising:
- a guide member having a proximal end portion and a distal end portion, the distal end portion of the guide member changeable from a generally linear deployment configuration for insertion into the intervertebral disc space to a pre-defined less linear deployed configuration within the intervertebral disc space;
- at least one tissue disruptor for disrupting tissue within or adjacent to the intervertebral disc space, the tissue disruptor insertable into the intervertebral disc space and longitudinally moveable along the guide member;
- and
- at least one tissue extractor for capturing and removing disrupted tissue from the intervertebral disc space, the tissue extractor insertable into the intervertebral disc space and longitudinally moveable along the distal end portion of the guide member.
A method of disrupting and removing tissue from an intervertebral disc space, comprising:
- guiding a tissue disruptor into an intervertebral disc space along a pre-defined path;
- disrupting tissue within or adjacent to the intervertebral disc space with the tissue disruptor;
- removing the tissue disruptor from the intervertebral disc space;
- guiding a tissue extractor into the intervertebral disc along the pre-defined path;
- and
- removing tissue from the intervertebral disc space with the tissue extractor.
