Apparatus For Testing Prosthetic Heart Valve Hinge Mechanism

US Patent:
55310940, Jul 2, 1996
Filed:
Nov 14, 1994
Appl. No.:
8/339476
Inventors:
Robert B. More - Austin TX
Peter Strzepa - Austin TX
Michael J. Mewhort - Pflugerville TX
Thomas S. Reventas - Austin TX
Assignee:
Carbomedics, Inc. - Austin TX
International Classification:
G01M 1900
US Classification:
73 4R
Abstract:
An apparatus for proof testing mechanical heart valve prostheses. The apparatus also provides an in vitro test environment simulating in vivo loads, providing a function test. If the heart valve passes the pivot proof test, a function test is performed. The apparatus first directs a pressurized back flow against the tested valve, closing the valve and applying pressure against the leaflet occluders well beyond the maximum functional in vivo load. The heart valve is positioned so that the leaflets assume their "worst-case" position, that is, the heart valve is oriented so that all the necessary play or gap between the leaflet pivots and pivot recesses is subsumed at one location, thus representing the most severe condition that might be experienced with a heart valve in use. The heart valve is loaded by back pressure applied through a working fluid. Pressure transponders detect the pressure on each side of the heart valve, to determine if a valid test has been performed.
