1. An elongate medical device, comprising:
a deflectable shaft section comprising a shaft material;
a handle operable to induce a cross-sectional bending of the deflectable shaft section;
a first lumen within the deflectable shaft section, wherein a cross-sectional shape of the first lumen comprises a peanut shape, wherein the peanut shape is defined by two circular areas joined by a waist area;
a first lumen liner comprising a first lumen liner material that surrounds and defines the first lumen, wherein the first lumen liner comprises a first lumen liner material that is stiffer than the shaft material to provide planarity control of the deflectable shaft section during the cross-sectional bending of the deflectable shaft section;
two second lumens within the deflectable shaft section, wherein the two second lumens are disposed diametrically opposed to one another on opposite sides of the first lumen; and
an irrigation tube disposed in the first lumen.
