    摘要： The invention includes a system and method for the loosening of tissue. In one embodiment, a device for use in an intervertebral tissue removal procedure includes a cannula having a first end portion for insertion into tissue, a feed passage within the cannula, a return passage within the cannula, and a loosening member movable within the feed passage and the return passage and at least partially deployable away from the first end portion of the cannula.

    摘要： 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.

    摘要： Disclosed herein are devices and methods for removing tissue. In one aspect, a device for removing tissue includes a hollow elongate member having an outer wall and a lumen, a selectively deployable tissue-cutting element extending from the hollow elongate member, and an actuation member extending through the lumen and coupled to the hollow elongate member at a location that is distal to the tissue-cutting element. Movement of the actuation member can cause the tissue-cutting element to move from the insertion configuration where the tissue-cutting element is not deployed to a tissue-cutting configuration where the tissue-cutting element is deployed such that it is radially extended relative to the insertion configuration.
