Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
134 words
An artificial heart valve composed of materials which are inert to the human body and which is capable of creating an electrical inductance which comprises: a. a valve housing having an annular base with a coil of wire encapsulated in a suitable plastic disposed around the perimeter of the annular base, said base having an opening therein, b. a pair of electrical leads emanating from said coil for attachment to an electrical circuit, c. a valve element having a magnet disposed therein, said element having a north pole and a south pole, said valve element adapted for movement within the valve housing whereby on the movement of said element from a distant position to a proximal position, the element closes off the opening in said annular base, thereby causing a current to be induced.
Claim 2
Dependent Claim
134 words
An artificial heart valve composed of materials which are inert to the human body and which is capable of creating an electrical inductance which comprises: a. a valve housing having an annular base with a coil of wire encapsulated in a suitable plastic disposed around the perimeter of the annular base, said base having an opening therein, b. a pair of electrical leads emanating from said coil for attachment to an electrical circuit, c. a valve element having a magnet disposed therein, said element having a north pole and a south pole, said valve element adapted for movement within the valve housing whereby on the movement of said element from a distant position to a proximal position, the element closes off the opening in said annular base, thereby causing a current to be induced.
Claim 3
Dependent Claim
14 words
The artificial heart valve of claim 1 wherein the valve element is bell shaped.
Claim 4
Dependent Claim
13 words

Claim 6
Dependent Claim
66 words
A pacemaker rechargeable battery charging system comprising in combination: a. a heart valve comprising an occluder element which contains a magnet and is capable of providing an inducted AC current, b. a diode rectifier electrically connected to said valve, c. a battery charger electrically connected to said diode rectifier and, d. a rechargeable battery adapted for use in a pacemaker, electrically connected to said battery charger.
Claim 7
Dependent Claim
66 words
A pacemaker rechargeable battery charging system comprising in combination: a. a heart valve comprising an occluder element which contains a magnet and is capable of providing an inducted AC current, b. a diode rectifier electrically connected to said valve, c. a battery charger electrically connected to said diode rectifier and, d. a rechargeable battery adapted for use in a pacemaker, electrically connected to said battery charger.
Claim 8
Dependent Claim
18 words
The pacemaker battery recharging system of claim 5 further including a current limiting means interposed in system's circuitry.
Claim 9
Dependent Claim
76 words
The pacemaker battery recharging system of claim 5 wherein the artificial heart valve capable of providing an induced current includes a valve housing having an annular base around which is disposed an encapsulated wire coil from which emanates a pair of leads and a central opening and a valve element having a magnet therein, said element adapted cooperate with said valve element whereby on closing of the opening in said valve housing a current is induced.
