Abstract
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.
Claims18
A testing system comprising:
- a body including;
- a main channel having a circuitous flow pattern for a fluid, defining a first flow path;
- a chamber connected to the main channel;
- a sub-channel that branches off the main channel, wherein a first end of the sub-channel is connected to the main channel and a second end of the sub-channel is fluidly connected to an upper side of the chamber, defining a second flow path;
- a user-actuatable gate disposed in either the main channel or the sub-channel to control an amount of fluid flow in the first flow path and in the second flow path;
- a piston mounted within the chamber, the piston having a reciprocating movement and including an opening at a bottom end of the piston;
- and
- at least one detachable holding mechanism to hold at least one prosthetic valve, the at least one detachable holding mechanism being positioned within the main channel at either side of the chamber, or within the opening in the piston.
A system for testing prosthetic heart valves, the system comprising:
- a housing;
- a main channel disposed within the housing having a circuitous flow pattern for a fluid, defining a first flow path;
- a chamber connected to the main channel;
- a sub-channel that branches off the main channel, wherein a first end of the sub-channel is connected to the main channel and a second end of the sub-channel is fluidly connected to an upper side of the chamber, defining a second flow path;
- a piston mounted within the chamber, the piston having a reciprocating movement;
- and
- at least one detachable holding mechanism to hold at least one prosthetic heart valve, the at least one detachable holding mechanism being positioned such that the prosthetic heart valve can be positioned within the main channel at either side of the chamber, or at a through-hole in the piston.
