Abstract
A testing apparatus is disclosed herein for testing properties of a prosthetic device. The testing apparatus may comprise a dual-drive pulsatile flow tester with the ability to determine coaptation of valve leaflets of a prosthetic device. The testing apparatus may be able to test prosthetic heart valves and reproduce physiological conditions of a prosthetic heart valve.
Claims20
A calibration device for use in a prosthetic device testing apparatus, the calibration device comprising:
- a plurality of walls spaced from each other;
- and
- at least one indicator on at least one of the plurality of walls indicating a position on the respective wall.
A method comprising:
- determining a scaling between an image distance and a real distance based on one or more images of a calibration device having a plurality of walls extending outward from each other and having a defined real distance between portions of the calibration device;
- and
- determining a property, based on the scaling, of one or more leaflets of a prosthetic valve shown in one or more images.
