1. A structure for deployment within an interior body cavity, comprising:

  • a distal hub having an axis, a proximal base, spline elements extending between the hub and the base in a circumferentially spaced relationship about the hub axis defining angular intervals between adjacent spline elements, the spline elements adapted to contact tissue within the interior body cavity, and two of the angular intervals being different by at least 20°

    to create a radially asymmetric geometry about the hub axis, wherein the distal hub has a side wall located about the axis, the hub including slots circumferentially spaced about the axis defining angular intervals between adjacent slots, the saline elements received in and retained by the slots.
