- the elongate body 130 includes a proximal portion (not shown), a distal portion 134, and an internal passageway 136 (see FIG. 3) extending from the proximal portion to the distal portion 134.
- the internal passageway 136 can be coupled to a source of suction or vacuum power (not shown).
- the elongate body 130 also includes an opening 146 defined on the distal portion 134 and an end cap 152 disposed on a distal end of the elongate body 130.
- the opening 146 on the elongate body 130 includes a cutting member 138 disposed around at least a portion of a perimeter of the opening 146.
- the cutting member 138 can be, for example, a sharp edge formed along a portion of the perimeter of the opening 146.
- the elongate body 130 can be movably disposed within the lumen 126 of the cannula 120.
- a seal or grommet 144 disposed on an outer surface of the elongate body 130 provides a sealing fit between the elongate body 130 and the cannula 120, while at the same time permitting the elongate body 130 to move within the lumen 126 of the cannula 120.
- the opening 146 can be at least partially aligned with one of the at least one windows 148.
- the cannula 120 can be inserted into an intervertebral disc such that the distal portion 124 is positioned within an interior of the disc.
- the elongate body 130 can be moved to a position within the cannula 120 such that the opening 146 at least partially aligns with a selected window 148.
- the suction power can suction tissue from within the interior of the disc at least partially through the window 148, and at least partially through the opening 146.
- the elongate body 130 can be moved within the lumen 126, for example, by either rotating the elongate body 130 about its longitudinal axis or pulling the elongate body 130 in the direction of its proximal end and/or its distal end such that opening 146 and window 148 move relative to each other from being at least partially aligned to being misaligned.
- the cutting member 138 on the opening 146 can sever the tissue that is at least partially positioned within the opening 146 from the remaining tissue within the disc. Once the tissue is severed, the suction force can pull the tissue through the internal passageway 136.
- the cutting member 138 can also be used to tear, loosen or disrupt tissue within the intervertebral disc by moving the elongate body 130 relative to the cannula 120. Because the opening 146 can be positioned such that the opening 146 is at least partially aligned with a selected one of the windows 148, tissue can be removed from various directions within the intervertebral disc without having to reposition the cannula 130. In other words, by aligning opening 146 with a given window 148 from the various windows 148 disposed about the circumference of the medical device 110, tissue can be removed from an area adjacent to a particular portion of the medical device 110 circumference.
