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
25 words
The method of claim 1 , wherein providing the natural valve includes providing a section of blood vessel containing at least one naturally occurring valve.
Claim 4
Dependent Claim
16 words
The method of claim 2 , wherein the section of blood vessel is a human vein.
Claim 5
Dependent Claim
15 words
The method of claim 2 , wherein the section of blood vessel is an autograft.
Claim 6
Dependent Claim
15 words
The method of claim 2 , wherein the section of blood vessel is an allograft.
Claim 7
Dependent Claim
15 words

Claim 11
Dependent Claim
93 words
A bypass system for implantation in a body of a patient, the system comprising: a tube having a first end and a second end and being configured to be implanted in a heart wall such that the first end is open towards a heart chamber and the second end is open towards a coronary vessel, the tube being further configured to permit blood to flow therethrough from the heart chamber to the coronary vessel; and a natural valve configured to restrict blood flow from the coronary vessel to the heart chamber during diastole.
Claim 12
Dependent Claim
93 words
A bypass system for implantation in a body of a patient, the system comprising: a tube having a first end and a second end and being configured to be implanted in a heart wall such that the first end is open towards a heart chamber and the second end is open towards a coronary vessel, the tube being further configured to permit blood to flow therethrough from the heart chamber to the coronary vessel; and a natural valve configured to restrict blood flow from the coronary vessel to the heart chamber during diastole.
