## Abstract

The invention is a gauge for the reconstruction of a cusp of an aortic valve, with the gauge (10) being made from a material that can be deformed in a plastic fashion using manual force.

## Claims

### Claim 1

A gauge for the reconstruction of a cusp of an aortic valve, characterized in that the gauge is made from a material that can be deformed in a plastic fashion upon manual force being applied.

### Claim 2 (depends on 1)

The gauge according to claim 1, wherein the gauge is made from a bio-compatible material.

### Claim 3 (depends on 1)

The gauge according to claim 1, wherein the gauge is made from a material that can be sterilized.

### Claim 4 (depends on 1)

The gauge according to claim 1, wherein the gauge is made from a material with bending characteristics exceeding 10 degrees.

### Claim 5 (depends on 1)

The gauge according to claim 1, wherein the gauge is made from a flexible steel, flexible aluminum, or flexible synthetic material.

### Claim 6 (depends on 1)
