Abstract:
1. A catheter system for operating on tissue at a surgical site in a patient, the catheter system comprising: an elongated shaft defining an axis, the shaft having a proximal end, a distal end, and an outer surface, the outer surface defining a circumference, and including at least one slot-like, non-circumferential cavity extending through at least a portion of the outer surface substantially perpendicular to the axis, the at least one cavity being configured to define a bending movement of the distal end relative to the proximal end; and a catheter tip attached to the distal end of the shaft, the catheter tip comprising a curved body having at least one cutting edge, and at least one non-cutting area recessed from the at least one cutting edge; wherein the bending movement of the distal end relative to the proximal end defined by the at least one cavity is adapted to facilitate deflection and steering of the shaft through the patient to the surgical site.
