Abstract
A collapsible and expandable implant for implanting in a heart chamber on a side of a heart. The implant may include an outer section including a curved portion configured to be positioned in the heart chamber. The implant may be sized such that an ellipsoid conforming to the curved portion has a height greater than a length of the heart chamber by a percentage that is within a predetermined range of height percentage values. The implant may be sized such that the ellipsoid has a width greater than a width of the heart chamber by a percentage that is within a predetermined range of width percentage values. The length and width of the heart chamber may be defined in an image of the heart chamber.
