Abstract

A surgical cutting instrument adapted for percutaneous insertion into a body cavity to facilitate a minimally invasive surgical procedure. The surgical cutting instrument includes a shaft having a proximal end, an open distal end, and an axial lumen therebetween. An inlet opening may be fluidly coupled to the lumen at a proximal end of the shaft, for connection to a vacuum source for creating a suction force sufficient to retain the distal end of the shaft adjacent to a surface of a body structure within the body cavity. A cutting element is disposed within the lumen of the shaft near the distal end of the shaft, and is operable to cut the body structure without removing any substantial portion of the body structure when the shaft is held adjacent to the surface of the body structure.
