SYSTEM AND METHOD FOR DENERVATION
First Claim
1. A method for manufacturing a shaping structure having a generally helical profile and configured to support electrodes for delivering electric energy into a cylindrical lumen of a patient, the method comprising:
- providing a mandrel with a circular cylindrical shape and having a proximal end and a distal end, a curved surface between the proximal end and the distal end, and an elongate axis;
forming a first hole in the mandrel along the elongate axis, such that opposing ends of a bore of the first hole emerge at the proximal end and at the distal end;
forming a second hole in the mandrel to extend from the curved surface to connect with the first hole, the second hole lying in a first radial plane of the mandrel;
forming a third hole in the mandrel to extend from the curved surface to connect with the first hole, the third hole lying in a second radial plane of the mandrel;
wrapping a metal wire around the mandrel in an area of the mandrel between the second hole and the third hole;
inserting opposing ends of the metal wire into the second and the third hole respectively, and threading the opposing ends of the metal wire until they emerge from the opposing ends of the bore of the first hole;
heating the mandrel and the wire.

16. A shaping structure having a generally helical profile and configured to support electrodes for delivering electric energy into a cylindrical lumen of a patient, the shaping structure comprising:
a wire formed of metal, and having a geometric shape described according to a three dimensional orthogonal coordinate system having an x-axis, a y-axis, and a z-axis, the wire being formed to include; a first element extending along the x-axis such that y=0, z=0 at all points on the first element; a second element extending along the x-axis such that y=0, z=0 at all points on the second element; and a third element, positioned between and operably connected with the first element and the second element, wherein the third element follows a spiral path with an axial length, a pitch, p, and a helical radius, r, about the x axis such that for any point on the third element, y=r*cos t, z=r*sin t, x=p*(t/2π
), where t is a parameter having a dimension in radians;wherein the third element is connected to the first element by a first connector that is straight and extends between a proximal end of the first element and a distal end of the third element, wherein the first connector forms an angle of between 70 degrees and 90 degrees with the x-axis. - View Dependent Claims (17, 18, 19, 20, 21, 22)
