Abstract
Abstract A method of flowing blood from a heart chamber to a coronary vessel includes providing a conduit with a first end and second end, providing the conduit within a heart wall such that the first end of the conduit is open towards the heart chamber and the second end is open towards the blood vessel, and during diastole, restricting a flow of blood from the coronary vessel to the heart chamber via the natural valve.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
82 words
A method of flowing blood from a heart chamber to a coronary vessel, the method comprising: providing a conduit with a first end and a second end; providing a natural valve; placing the conduit within a heart wall such that the first end of the conduit is open towards the heart chamber and the second end is open towards the blood vessel; and during diastole, restricting a flow of blood from the coronary vessel to the heart chamber via the natural valve.
Claim 2
Independent Claim
82 words
A method of flowing blood from a heart chamber to a coronary vessel, the method comprising: providing a conduit with a first end and a second end; providing a natural valve; placing the conduit within a heart wall such that the first end of the conduit is open towards the heart chamber and the second end is open towards the blood vessel; and during diastole, restricting a flow of blood from the coronary vessel to the heart chamber via the natural valve.
Claim 3
Dependent Claim
