A testing system for testing a prosthetic valve. The system includes a housing having a main channel defines a circuitous flow path for a fluid. The solid housing also includes a chamber which in turn includes a piston having an opening at the bottom end. The piston moves in a reciprocating motion within the chamber. Further, a holding mechanism, for holding a prosthetic valve, is positioned within the main channel at either or both sides of the chamber, or within the opening in the piston. A user of the device may selectively control a flow path of the fluid between 1). having the fluid flow through the prosthetic valve installed in the piston, and 2). having no fluid passing though the piston. |
