Apparatuses and methods for debulking a tissue in a patient's body are disclosed herein. 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.
