1. An annulus plane catheter, comprising:
a multilumen catheter having a proximal end and a distal end, said multi-lumen catheter having radiopaque markers and curvatures and sized to enclose at least two shaped wire lumens, said multilumen catheter having two distal wire ports proximate said distal end;
first and second shaped wire lumens disposed in said multilumen catheter, each of said shaped wired lumens having a proximal end with a shaped wire insertion port and an open distal end at one of said distal wire ports;
a pigtail catheter connected to said distal end of said multilumen catheter;
two radiopaque shaped wires, one each slidingly disposed in one of said shaped wire lumens, each of said shaped wires having a proximal end and a distal end and sized to fit into a range of annulus diameters and/or depths; and
a catheter delivery handle including a housing defining a substantially hollow interior space and having a proximal end and a distal end, said distal end capturing and enclosing said multilumen catheter, and first and second longitudinal slots disposed in said housing;
first and second thumb/finger-actuated sliders operatively coupled to respective first and second shaped wires and slidingly disposed in a respective one of said first and second longitudinal slots to enable extension and retraction of said shaped wires through said lumens;
wherein said longitudinal slots in said handle have a width sufficient to enable side-to-side motion of said sliders, thereby enabling a torque to be imparted to and translated down said first and second shaped wires to said distal end of said first and second shaped wires, such that said distal end of each of said shaped wires may be individually controlled and rotated to address differing annulus diameters.
