Embodiment Construction

[0021] The medical devices described herein are configured to be deployed percutaneously in internal regions of a patient's body, such as the patient's hard tissue (eg, skeletal structure) or soft tissue, to resect, split, separate, and / or cut portions of tissue within the tissue. For example, a medical device according to an embodiment of the present invention includes a cutting portion that can resect, split, separate, and / or cut tissue within a tissue region of a patient, or a portion of tissue, such as a tumor. In some embodiments, a medical device includes a device having an outer body and an inner body, wherein the inner body is movably disposed within the outer body. The inner body and / or the outer body may be elastic. The device may also include a resilient guide member for manipulating the device within the patient's tissue.

[0022] It should also be noted that, as used in the specification and the appended claims, the singular forms "a", "an" and "the" include plur...

Abstract

The present invention discloses apparatuses and methods for debulking a tissue in a patient's body. In one variation, an apparatus includes a cannula configured to provide percutaneous access to an interior portion of a tissue. The cannula has a distal portion, a proximal portion, and a lumen defined between the distal portion and the proximal portion. A flexible member is coupled to the cannula and configured to steer the distal portion of the cannula within the tissue. An elongate body has a distal portion and is configured to be movably disposed within the lumen of the cannula. The distal portion of the elongate body defines a cutting portion configured to disrupt at least a portion of the tissue when the cutting portion is moved, for example, rotated and / or shuttled. In one variation, the disrupted portion of tissue includes a portion of a tumor.

Description

technical field [0001] This application claims priority to U.S. Patent Application Serial No. 11 / 448,975, filed June 8, 2006, entitled "Tissue Debulking Device and Method of Using the Same" rights, the disclosure is hereby incorporated by reference in its entirety. Background technique [0002] The present invention relates generally to medical devices and procedures, and more particularly to medical devices for percutaneous access to tissue and removal of portions of tissue. [0003] Known medical devices are configured to percutaneously access tissue, such as vertebrae or other areas of the spine, to perform a variety of different medical procedures. Some known medical devices are configured to remove tissue from the interior of vertebrae or intervertebral discs. Other known medical devices are configured to provide some type of cutting device to tear or cut tissue within a vertebra or intervertebral disc. [0004] There may also be various medical devices configured to...
