Expandable intervertebral tool system and method
First Claim
1. An intervertebral tissue removal system comprising:
- at least one abrading member for abrading tissue in an area to be cleared;
at least one expandable member including a housing and at least one node, the node operable to be expanded from a first condition to a second condition, wherein a first end portion of the at least one abrading member is fixed to the housing and the volume defined by the at least one expandable member in the second condition is greater than the volume defined by the at least one expandable member in the first condition, the at least one expandable member operably connected to a second portion of the at least one abrading member that is not fixed to the housing such that as the at least one node expands from the first condition to the second condition, the at least one abrading member is pivoted by the at least one node from a first position to a second position;
an expansion media for insertion within the at least one expandable member; and
an expansion media conduit connected to the at least one expandable member for delivering the expansion media to the at least one expandable member to expand the at least one expandable member from the first condition to the second condition.

Abstract
The invention includes a system and method for loosening of tissue. In one embodiment, an intervertebral tissue removal system includes at least one abrading member for abrading tissue in an area to be cleared and at least one expandable member operable to be expanded from a first condition to a second condition, wherein the volume defined by the at least one expandable member in the second condition is greater than the volume defined by the at least one expandable member in the first condition, the at least one expandable member operably connected to the at least one abrading member such that as the at least one expandable member expands from the first condition to the second condition, the at least one abrading member is moved from a first position to a second position. The system includes an expansion media for insertion within the at least one expandable member and an expansion media conduit for delivering the expansion media to the at least one expandable member to expand the at least one expandable member from the first condition to the second condition.

25. An intervertebral tissue removal system comprising:
-
at least one abrading member for abrading tissue in an area to be cleared; at least one deformable member configured to be reversibly deformed from a first shape to a second shape, the at least one deformable member operably connected to the at least one abrading member such that as the at least one deformable member deforms from the first shape to the second shape, the at least one abrading member is moved from a first position to a second position; a non-liquid segmented expansion media configured to be inserted within the at least one deformable member and configured to be removed from the at least one deformable member; and an expansion media conduit connected to the at least one deformable member for delivering the expansion media to the at least one deformable member to deform the at least one deformable member from the first shape to the second shape. - View Dependent Claims (26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37)

38. A method of loosening intervertebral tissue comprising:
-
inserting at least one abrading member for abrading tissue into an area to be cleared; expanding at least one expandable member from a first condition to a second condition, wherein the volume defined by the at least one expandable member in the second condition is greater than the volume defined by the at least one expandable member in the first condition; moving a portion of the inserted at least one abrading member that is not affixed to a housing of the at least one expandable member from a first position to a second position by the expansion of the at least one expandable member while a second portion of the at least one abrading member is fixed to a housing of the at least one expandable member; manipulating the inserted at least one abrading member to loosen tissue; and removing the loosened tissue from the area to be cleared. - View Dependent Claims (39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49)
