Patent ID: 7695451

Claim:
An apparatus, comprising: an elongate body proximal portion having a proximal end and a distal end and including a wall, defining an inner surface, an outer surface and a central lumen that extends from the proximal end to the distal end, and a steering wire lumen offset from the central lumen, located within the wall between the inner surface and the outer surface, extending from the proximal end to the distal end of the elongate body proximal portion and defining a circular cross-section; an elongate body distal portion having a proximal end secured to the distal end of the elongate body proximal portion and including a wall, defining an inner surface, an outer surface and a central lumen extending from the proximal end of the elongate body proximal portion to a distal end aperture, and a steering wire lumen offset from the central lumen, located within the wall between the inner surface and the outer surface, extending from the proximal end to the distal end of the elongate body distal portion and defining a non-circular cross-section; and a steering wire having a proximal portion defining a circular cross-section and a distal portion defining a non-circular cross-section, the distal portion of the steering wire being operably connected to the distal portion of the elongate body at a location offset from the central lumen.
