A valve cusp sizer comprising:
- an outer peripheral surface having an arcuate shape and configured to be brought into contact with a living body;
- a plurality of portions to be supported comprising a first portion to be supported and a second portion to be supported, each of the first portion to be supported and the second portion to be supported protruding from an inner peripheral surface of the valve cusp sizer, and the first portion to be supported being disposed at a first end in a circumferential direction of the valve cusp sizer and the second portion to be supported being disposed at a second end in the circumferential direction of the valve cusp sizer;
- and
- each of the plurality of portions to be supported comprising a hole configured to receive a support rod, wherein
- each of the first portion to be supported and the second portion to be supported are positioned at a same distance from a center of the arcuate shape in a left-right direction.

A valve cusp sizer comprising:
- an outer peripheral surface having an arcuate shape and configured to be brought into contact with a living body;
- a first portion to be supported protruding orthogonally from an inner peripheral surface of the valve cusp sizer at a left-side end in a circumferential direction of the valve cusp sizer;
- a second portion to be supported protruding orthogonally from the inner peripheral surface of the valve cusp sizer at a right-side end in a circumferential direction of the valve cusp sizer,
- wherein each of the first portion to be supported and the second portion to be supported comprise a hole configured to receive a support rod, and
- wherein each of the first portion to be supported and the second portion to be supported are positioned at a same distance from a center of the arcuate shape in a left-right direction.

A plurality of valve cusp sizer, each valve cusp sizer of the plurality of valve cusp sizer comprising:
- an outer peripheral surface having an arcuate shape and configured to be brought into contact with a living body;
- a first portion to be supported protruding orthogonally from an inner peripheral surface of the valve cusp sizer at a left-side end in a circumferential direction of the valve cusp sizer;
- a second portion to be supported protruding orthogonally from the inner peripheral surface of the valve cusp sizer at a right-side end in a circumferential direction of the valve cusp sizer;
- a convex portion protruding in the circumferential direction from a first end face of the valve cusp sizer;
- and
- a concave portion extending in the circumferential direction into a second end face of the valve cusp sizer,
- wherein each of the first portion to be supported and the second portion to be supported comprise a hole configured to receive a support rod, and
- wherein the convex portion is configured to be connected to the convex portion of other of the plurality of valve cusp sizers.
