摘要：
In one embodiment, an apparatus includes an elongate body having a collapsed configuration and an expanded configuration. The elongate body has a cutting portion at a distal portion of the elongate body, and the cutting portion defines an opening in the elongate body. The distal portion of the elongate body is configured to be inserted into a nucleus of an intervertebral disc when the elongate body is in the collapsed configuration. The cutting portion of the elongate body is configured to disrupt at least a portion of tissue within the nucleus of the intervertebral disc when the elongate body is in the expanded configuration. The elongate body is configured to capture the portion of tissue within the opening of the elongate body when the elongate body is moved from the expanded configuration to the collapsed configuration while disposed within the nucleus of the intervertebral disc.
