Minimally invasive system for manipulating intervertebral disc tissue
First Claim
Patent Images
1. A method of manipulating a bodily tissue, wherein the tissue is enclosed by a definable outer layer of the same or different bodily tissue, the method comprising:
- locating an opening in the outer layer;
inserting within said opening to a point past the outer layer a distal end of a hollow cannula, said cannula having a proximal end and a distal end and having an elongated longitudinal axis, said cannula slideably housing an advancer coupled to a probe member, said probe member having a proximal end connected to the advancer and said distal end of said probe member connected to a tip, said distal end of the probe member capable of being advanced and retracted through a curved slot at the distal end of the cannula via longitudinal movement of the advancer within said cannula; and
advancing the advancer within the cannula and causing the probe member to be advanced outward from the curved passage at an angle between 30 and 150 degrees relative to the long axis of the cannula such that the probe tip travels and manipulates tissue parallel to the intersection of the tissue with the definable outer layer of tissue.

Abstract
The present invention relates generally to intervertebral disc devices and methods and instrumentation for intervertebral disc procedures. An intervertebral disc repair and diagnostic device that is minimally invasive, actively guided, and provides direct and consistent access to the inner surface of the posterior anulus, which will not unintentionally exit the posterior anulus and cause harm to the spinal cord, is provided.

9. A method of manipulating tissue within an intervertebral disc comprising:
-
inserting an insertion device into the intervertebral disc along a first axis;
deploying a probe having a probe tip laterally from the insertion device within the intervertebral disc along a second axis which is substantially transverse to the first axis; and
manipulating tissue via extending the probe tip across or through said tissue.
