An apparatus and method for removing tissue and/or other material from a patient includes a shaft and a tissue disrupting mechanism operatively coupl ed to the shaft. The shaft may be coupled to a handpiece or a robotic or rem ote-controlled system. The mechanism may comprise a rotatable or other movab le element having a distal portion with fixed or adjustable radial dimension s. The mechanism may have one or more tissue cutting, chopping, grinding, em ulsifying or disrupting features with an adjustable outer diameter for remov ing substantial tissues. The apparatus may be configured to urge or draw sub stantial material into the device upon rotation or other movement of the sha ft and/or tissue, and may optionally be coupled to sources of suction or asp iration. A radiofrequency or other energy source is optionally included for tissue ablation or other tissue remodeling effects, and/or to enhance coagul ation.
