Abstract
An apparatus for cutting a wall of a vessel, such as scoring or slicing a lesion associated therewith. A catheter (10) includes a shaft (12) having a distal portion supporting a housing (20) including a first lateral passage (20a). A cutter (22) is adapted for moving from a retracted position within the housing (20) to a deployed position for at least partially projecting from the passage (20a). A expandable actuator (24) within the housing (20), such as an inflatable balloon (26), actuates the cutter (22) to move from the retracted position fully within the housing (20) to the deployed position at least partially projecting from the housing (20). More than one cutter (22′) may be provided, which cutters (22′) may be simultaneously actuated by the same actuator (26′).
