Device and method for regulating blood flow
First Claim
1. A system for regulating a blood flow rate or blood pressure to achieve balanced flow rates or blood pressures between a first blood vessel or heart chamber and a second blood vessel or heart chamber, wherein the first blood vessel or heart chamber and the second blood vessel and heart chamber are on opposite sides of the circulatory system, and wherein the first blood pressure or heart chamber is regulated by the system only by a regulator applied to the second blood vessel or heart chamber, the system comprising:
- i) a monitor monitoring parameters indicative of a difference between the flow rate or blood pressure of the first blood vessel or heart chamber and the flow rate or blood pressure of the second blood vessel or heart chamber;
ii) the regulator regulating the blood flow rate or blood pressure in at least a portion of the second blood vessel or heart chamber; and
iii) a controller configured to;
receive a signal from the monitor;
determine from the signal a difference between the flow rate or blood pressure of the first blood vessel or heart chamber and the flow rate or blood pressure of the second blood vessel or heart chamber;
determine from the difference between the flow rate or blood pressure of the first blood vessel or heart chamber and the flow rate or blood pressure of the second blood vessel or heart chamber a second blood flow rate or blood pressure in the second blood vessel or heart chamber that generates a second blood flow rate or blood pressure in the first blood vessel or heart chamber to yield the balanced flow rate or blood pressure between the first blood vessel or heart chamber and the second blood vessel or heart chamber; and
signal the regulator to generate the second determined blood flow rate or blood pressure in the at least portion of the lumen of the second blood vessel or heart chamber.

Abstract
A system and method for regulating blood flow rate or blood pressure in a second blood vessel or heart chamber to achieve a balanced flow rate or blood pressure between the second blood vessel or heart chamber and a first blood vessel or heart chamber, wherein the first and the second blood vessels and heart chambers are on opposite sides of the circulatory system. The system comprises a monitor that monitors parameters indicative of a difference between the flow rates or blood pressures of the first and the second blood vessels or heart chambers. A regulator regulates the blood flow rate or blood pressure in at least a portion of the second blood vessel or heart chamber. A controller is configured to receive a signal from the monitor and to determine a difference between the flow rate or blood pressure of the first blood vessel or heart chamber and the flow rate or blood pressure of the second blood vessel or heart chamber. The controller determines a second blood flow rate or blood pressure in the second blood vessel or heart chamber that generates the balanced flow rate or blood pressure between the first and the second blood vessels or heart chambers. The controller then signals the regulator to generate the second determined blood flow rate or blood pressure in the at least portion of the lumen of the second blood vessel or heart chamber.

9. A method for regulating a blood flow rate or blood pressure to achieve balanced flow rates or blood pressures between a first blood vessel or heart chamber and a second blood vessel or heart chamber, wherein the first blood vessel or heart chamber and the second blood vessel and heart chamber are on opposite sides of the circulatory system, and wherein the first blood pressure or heart chamber is regulated by the system only by a regulator applied to the second blood vessel or heart chamber, the method comprising:
-
i) monitoring parameters indicative of a difference between the flow rate or blood pressure of the first blood vessel or heart chamber and the flow rates or blood pressure of the second blood vessel or heart chamber; ii) determining a difference between the flow rate or blood pressure of the first blood vessel or heart chamber and the flow rate or blood pressure of the second blood vessel or heart chamber from the signal; iii) determining from the difference between the flow rate or blood pressure of the first blood vessel or heart chamber and the flow rate or blood pressure of the second blood vessel or heart chamber a second blood flow rate or blood pressure in the second blood vessel or heart chamber that generates a second blood flow rate or blood pressure in the first blood vessel or heart chamber to yield the balanced flow rate or blood pressure between the first blood vessel or heart chamber and the second blood vessel or heart chamber; and iv) generating the second determined blood flow rate or blood pressure in the at least portion of the lumen of the second blood vessel or heart chamber. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. Apparatus for regulating a blood flow rate or blood pressure to achieve balanced flow rates or blood pressures between a first blood vessel or heart chamber and a second blood vessel or heart chamber, the first blood vessel or heart chamber and the second blood vessel and heart chamber on opposite sides of the circulatory system, comprising:
-
a processor capable of; i) monitoring parameters indicative of a difference between the flow rate or blood pressure of the first blood vessel or heart chamber and the flow rates or blood pressure of the second blood vessel or heart chamber; ii) determining a difference between the flow rate or blood pressure of the first blood vessel or heart chamber and the flow rate or blood pressure of the second blood vessel or heart chamber from the signal; iii) determining from the difference between the flow rate or blood pressure of the first blood vessel or heart chamber and the flow rate or blood pressure of the second blood vessel or heart chamber a second blood flow rate or blood pressure in the second blood vessel or heart chamber that generates a second blood flow rate or blood pressure in the first blood vessel or heart chamber to yield the balanced flow rate or blood pressure between the first blood vessel or heart chamber and the second blood vessel or heart chamber; and iv) generating the second determined blood flow rate or blood pressure in the at least portion of the lumen of the second blood vessel or heart chamber below a naturally occurring blood flow rate or blood pressure; a regulator effecting control of flow rate or blood pressure at the second blood vessel or heart chamber, the method. - View Dependent Claims (18)
