Flow regulating device in the heart
A blood flow regulator for creating a shunt in the heart, comprising; a proximal element having a general disc-shape, defined by a braid of one or more wires extending about a central aperture of the proximal element; a distal element having a general disc-shape, defined by a braid of one or more wires extending about a central aperture of the distal element; and a third element defining a neck section intermediate the proximal and distal elements and forming a cavity having a diameter no greater than a diameter of each of the distal and proximal elements, wherein said distal element comprises at least one loop of a wire extending radially outwardly from a center of the distal element and returning towards said center of said distal element.
1. A method of shunting a heart comprising:
providing a braided flow control device having a disc-shaped proximal element, a disc-shaped distal element, a neck section therebetween and no more than one connecting element, said one connecting element disposed on said proximal element;
delivering said braided flow control device through a catheter to a rupture in a wall of a heart chamber;
urging force against said one connecting element to deploy said braided flow control device until said disc-shaped distal element and said disc-shaped proximal element are positioned on either side of said rupture in said wall of a heart chamber
allowing said braided flow control device to thereby control blood flow across said rupture of said heart.
2. A method according to claim 1 , wherein urging force against said one connecting element comprises urging force against a plurality of wires that make up said braided flow control device, said plurality of wires terminating at said connecting element.
3. A method according to claim 1 , wherein urging force against said one connecting element comprises urging force against a spherically shaped connecting element.
4. A method according to claim 1 , further comprising puncturing a hole in said wall of a heart chamber to create said rupture.
5. A method according to claim 1 , wherein said wall of a heart chamber is an atrial septum.
6. A method according to claim 1 , wherein urging force against said one connecting element comprises pushing against a cable in contact with said one connecting element.
7. A method of affecting blood flow in a heart comprising:
providing a flow control device having a proximal element, a distal element, a neck section therebetween and no more than one connecting element, said one connecting element disposed on said proximal element;
delivering said flow control device through a catheter to a rupture in a wall of a heart chamber;
urging force against said one connecting element to deploy said flow control device until said distal element and said proximal element are positioned on either side of said rupture in said wall of a heart chamber
allowing said braided flow control device to thereby control blood flow across said rupture of said heart.
8. A method according to claim 7 , wherein said distal and proximal elements are disc-shaped.
9. A method according to claim 7 , wherein said flow control device is comprised of a plurality of wires that originate and terminate at said one connecting element.
10. A method according to claim 7 , wherein urging force against said one connecting element comprises urging force against a plurality of wires that make up said flow control device, said plurality of wires originating and terminating at said connecting element.
11. A method according to claim 7 , wherein urging force against said one connecting element comprises urging force against a spherically shaped connecting element.
12. A method according to claim 7 , further comprising puncturing a hole in said wall of a heart chamber to create said rupture.
13. A method according to claim 7 , wherein said wall of a heart chamber is an atrial septum.
14. A method according to claim 7 , wherein urging force against said one connecting element comprises pushing against a cable in contact with said one connecting element.
