General description

This sizer is designed to simulate the insertion of heart valve prosthetics into 3d printed patient phantoms. It is loosely based on the size specifications of a Sapien XT valve (adjustable diameter ranging across 20 - 29 mm, with adjustments to 23, 26 and 29 mm; fixed height of 16 mm). The basic design of the sizer includes a central stud and an expandable cylindrical simulated valve. Rotation of the central stud clockwise and counter-clockwise causes the simulated valve to expand and contract respectively, thus simulating multiple diameters in succession.

Hardware

Additional hardware parts need to be pruchased for the complete assembly:

The central stud x1 (https://www.mcmaster.com/#94455a344/=19b9ya1)
The left-turning end nut x1 (https://www.mcmaster.com/#99891a120/=19bau20)
The right-turning end nut x1 (https://www.mcmaster.com/#95462a031/=19baumu)
Aluminum flashing 0.0078 inch thickness or similar

The stl file is scaled up to 2x. This facilitates usage and ensures its rigidity. The patient phantoms should also be printed at 2x. No further finishing required.
