Apparatus and methods of tissue removal within a spine
First Claim
1. An apparatus, comprising:
- a cannula configured to provide percutaneous access to a nucleus of an intervertebral disc, the cannula defining a lumen and an opening in communication with the lumen of the cannula; and
an elongate body defining an internal passageway and an opening at a distal portion of the elongate body in communication with the internal passageway, the elongate body configured to be movably disposed within the lumen of the cannula, the elongate body having a cutting portion disposed on an edge of the opening, the internal passageway of the elongate body being configured to be coupled to a suction source, the elongate body configured to draw a portion of tissue from within the nucleus of the intervertebral disc into the opening of the elongate body when the suction source is activated, the cutting portion configured to sever the portion of tissue from the remaining tissue when the elongate body is moved relative to the cannula.

Abstract
In one embodiment, an apparatus includes a cannula configured to provide percutaneous access to a nucleus of an intervertebral disc, and an elongate body configured to be movably disposed within a lumen of the cannula. The cannula also defines an opening. The elongate body defines an internal passageway and an opening at a distal portion of the elongate body. The internal passageway of the elongate body can be coupled to a suction source. The elongate body has a cutting portion disposed on an edge of the opening of the elongate body and the elongate body is configured to draw a portion of tissue from within the nucleus of the intervertebral disc into the opening of the elongate body when the suction source is activated. The cutting portion is configured to sever the portion of tissue from the remaining tissue when the elongate body is moved relative to the cannula.
