Abstract
Abstract A heart valve apparatus includes a circular valve ring having a passageway therethrough and forming a valve seat around the passageway opening. A disk shaped valve element is shaped to cover the valve opening and to seat in the valve seat. The valve ring has a ring link bracket attached thereto, while the valve element has a valve element link bracket attached on one side thereof. A linkage is movably attached between the ring link bracket and the valve element link bracket to thereby allow the valve element to swing open and closed against the valve seat. The valve link has stop elements for preventing the swing of the valve link and the rotation of the valve element thereon. Two attracting permanent magnets are positioned at base of the link and valve ring to hold the valve link and valve element open until a predetermined force from pivoting valve element on the return flow, releases the link from the magnets for closing of the valve. There are two repelling opposing magnets, one in the valve element, and one in the pivotal stop on the valve link to the valve element. These magnets have like poles facing each other, and repel each other on contact to cushion the pivoting valve element on the opening, and to allow the valve element to open fully perpendicular to valve ring, and to reduce noise, and to give the valve element a nudge into return flow for closing. The forward flow is enough to keep valve element fully open against force of repelling magnets until the reverse flow starts.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
156 words
A heart valve comprising in combination: a circular valve ring having a passageway therethrough and forming a valve seat around the periphery of the passageway therethrough; a disk shaped valve element shaped to cover the passageway through the valve ring and to seat in the valve seat formed therein; a valve element link bracket fixably attached to one side of the valve element; a valve link member movably attached to said valve element link bracket; said valve link member having a magnet formed in one end portion thereof; a valve ring link bracket fixably attached to said valve ring and having said link movably attached thereto; whereby said valve element can move on said link member and said link member can move on said ring during the opening and closing of said valve element; and said circular valve ring having a valve link member attaching bracket formed thereon for movably supporting the valve link member thereto.
Claim 2
Dependent Claim
156 words
A heart valve comprising in combination: a circular valve ring having a passageway therethrough and forming a valve seat around the periphery of the passageway therethrough; a disk shaped valve element shaped to cover the passageway through the valve ring and to seat in the valve seat formed therein; a valve element link bracket fixably attached to one side of the valve element; a valve link member movably attached to said valve element link bracket; said valve link member having a magnet formed in one end portion thereof; a valve ring link bracket fixably attached to said valve ring and having said link movably attached thereto; whereby said valve element can move on said link member and said link member can move on said ring during the opening and closing of said valve element; and said circular valve ring having a valve link member attaching bracket formed thereon for movably supporting the valve link member thereto.
Claim 3
Dependent Claim
41 words
A heart valve in accordance with claim 1 in which said circular valve ring has a slope formed therein from one side of the ring to the other, thereby providing a drop-off in the velocity of the flow of fluid therethrough.
Claim 4
Dependent Claim
32 words
A heart valve in accordance with claim 1 in which said circular valve ring has an annular groove therearound and suturing material formed therein for attaching the heart valve to a patient.
Claim 5
Dependent Claim
33 words
A heart valve in accordance with claim 1 including a heart valve link shield attached to said circular valve ring adjacent connecting means connecting said valve link member to said circular valve ring.
Claim 6
Dependent Claim
56 words
A heart valve in accordance with claim 3 in which the circular valve ring has a magnet formed therein facing the magnet attached to said valve link member and having an opposite magnetic polarity forming the magnet in said valve link member, whereby said magnets can attract and hold one to the other in one position.
Claim 7
Dependent Claim
19 words
A heart valve in accordance with claim 5 in which said valve link member has a second magnet therein.
Claim 8
Dependent Claim
76 words
A heart valve in accordance with claim 6 in which said disk shaped valve element has a magnet formed therein and positioned adjacent to the second magnet formed in said valve link member when said disk shape valve element is in an open position and said magnets having facing like polarities opposite to each other for repelling said disk shape valve element to return the valve element into the return flow to partially close the valve.
Claim 9
Dependent Claim
31 words
A heart valve in accordance with claim 4 in which said valve link member has a stop surface formed thereon for stopping the rotation of said disk shaped valve element thereon.
Claim 10
Dependent Claim
35 words
A heart valve in accordance with claim 8 in which said link member has a second stop surface for stopping the rotation of said valve link member on said circular valve ring in one position.
Claim 11
Dependent Claim
168 words
A heart valve comprising in combination: a circular valve ring having a passageway therethrough and forming a valve seat around the periphery of the passageway therethrough; a disk shaped valve element shaped to cover the passageway through the valve in one position and to seat in the valve seat formed therein and to rotate from said one position to a second position; a valve element support arm fixedly attached to said circular valve ring and having said valve element rotably attached thereto for rotating thereon; and magnetic means for repelling said disk shaped valve element and moving said valve element into the return flow for closing said magnetic means including a permanent magnet mounted in said disk shape element and a second permanent magnet mounted in said disk shape valve element support arm, said magnets having the same polarity facing each other and being juxtaposed adjacent each other in one position for repelling said disk shaped valve element and moving the valve element into return flow for closing.
Claim 12
Dependent Claim
168 words
A heart valve comprising in combination: a circular valve ring having a passageway therethrough and forming a valve seat around the periphery of the passageway therethrough; a disk shaped valve element shaped to cover the passageway through the valve in one position and to seat in the valve seat formed therein and to rotate from said one position to a second position; a valve element support arm fixedly attached to said circular valve ring and having said valve element rotably attached thereto for rotating thereon; and magnetic means for repelling said disk shaped valve element and moving said valve element into the return flow for closing said magnetic means including a permanent magnet mounted in said disk shape element and a second permanent magnet mounted in said disk shape valve element support arm, said magnets having the same polarity facing each other and being juxtaposed adjacent each other in one position for repelling said disk shaped valve element and moving the valve element into return flow for closing.
