Abstract
Abstract A transmyocardial implant includes a hollow conduit inserted through a heart wall. The conduit defines a blood flow path between a heart chamber opening and a vessel opening. The heart chamber opening of the conduit is placed in communication with a chamber of the heart. A coronary vessel on an exterior of the heart wall is severed into a proximal portion and a distal portion. The distal portion of the vessel is placed into the vessel opening of the conduit. An alternative embodiment places the vessel flush with the vessel opening of the conduit.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
148 words
A method for performing a coronary bypass procedure at a coronary vessel disposed lying at an exterior of a heart wall, the method comprising: inserting a hollow conduit through the heart wall where the conduit has an interior wall defining a blood flow path between a heart chamber opening and a vessel opening, said inserting including placing the heart chamber opening of the conduit in communication with a chamber of the heart; severing the vessel into a proximal portion and a distal portion and dissecting free a length of the distal portion sufficient to insert the dissected length into the conduit; inserting the dissected length of the distal portion of the vessel into the vessel opening of the conduit with an exterior of the dissected length opposing the interior wall of the conduit; and securing the dissected length of the distal portion of the vessel to the conduit.
Claim 2
Independent Claim
148 words
A method for performing a coronary bypass procedure at a coronary vessel disposed lying at an exterior of a heart wall, the method comprising: inserting a hollow conduit through the heart wall where the conduit has an interior wall defining a blood flow path between a heart chamber opening and a vessel opening, said inserting including placing the heart chamber opening of the conduit in communication with a chamber of the heart; severing the vessel into a proximal portion and a distal portion and dissecting free a length of the distal portion sufficient to insert the dissected length into the conduit; inserting the dissected length of the distal portion of the vessel into the vessel opening of the conduit with an exterior of the dissected length opposing the interior wall of the conduit; and securing the dissected length of the distal portion of the vessel to the conduit.
Claim 3
Dependent Claim
35 words
A method according to claim 1 wherein the vessel is a coronary artery and the heart chamber is a left ventricle, said method further comprising severing the artery distal to an obstruction in the artery.
Claim 4
Dependent Claim
32 words
A method according to claim 1 wherein the dissected length of the distal portion of the coronary vessel is inserted into a full length of the conduit to the heart chamber opening.
Claim 5
Dependent Claim
31 words
A method according to claim 3 wherein the dissected length of the distal portion of the coronary vessel is wrapped around an exterior of the conduit at the heart chamber opening.
Claim 6
Dependent Claim
36 words
A method according to claim 1 wherein the dissected length of the distal portion of the coronary vessel is inserted into the conduit at the vessel opening and secured to the conduit adjacent the vessel opening.
Claim 7
Independent Claim
141 words
A method for performing a coronary bypass procedure at a coronary vessel disposed lying at an exterior of a heart wall, the method comprising: inserting a hollow conduit through the heart wall where the conduit has an interior surface defining a blood flow path between a heart chamber opening and a vessel opening, said inserting including placing the heart chamber opening of the conduit in communication with a chamber of the heart; severing the vessel into a proximal portion and a distal portion; attaching the distal portion of the vessel to the conduit at the vessel opening of the conduit with an interior surface of the distal portion of the vessel substantially flush and continuous with the interior surface of the conduit to define a substantially continuous, uniform diameter transition between said blood flow path and a lumen of said vessel.
Claim 8
Independent Claim
141 words
A method for performing a coronary bypass procedure at a coronary vessel disposed lying at an exterior of a heart wall, the method comprising: inserting a hollow conduit through the heart wall where the conduit has an interior surface defining a blood flow path between a heart chamber opening and a vessel opening, said inserting including placing the heart chamber opening of the conduit in communication with a chamber of the heart; severing the vessel into a proximal portion and a distal portion; attaching the distal portion of the vessel to the conduit at the vessel opening of the conduit with an interior surface of the distal portion of the vessel substantially flush and continuous with the interior surface of the conduit to define a substantially continuous, uniform diameter transition between said blood flow path and a lumen of said vessel.
