Left ventricular conduits and methods for delivery

A method of delivering a conduit into a heart wall between a heart chamber and an adjacent blood vessel, comprising:

• inserting a hollow needle through an anterior wall and a posterior wall of the blood vessel through the heart wall and into the heart chamber;
• inserting a guidewire through the hollow needle into the heart chamber;
• removing the hollow needle;
• inserting a dilator over the guidewire into the heart wall;
• removing the guidewire;
• and
• placing a conduit over the dilator into the heart wall,
• wherein placing the conduit includes screwing the conduit into the heart wall.

A method of providing direct blood flow between a heart chamber and a coronary vessel, the method comprising:

• placing a guide device through an anterior wall and a posterior wall of the coronary vessel and through a heart wall between the heart chamber and the coronary vessel;
• forming a passageway in the heart wall at a location defined by the guide device;
• placing a conduit within the passageway;
• and
• delivering via the guide device a first mechanism for forming the passageway and a second mechanism for placing the conduit within the passageway.

A method for inserting a conduit into a heart wall between a heart chamber and the coronary artery, comprising:

• screwing a stylet having a threaded tip and a nonthreaded body portion into the heart wall;
• screwing an outer sleeve having a threaded exterior over the nonthreaded body portion of the stylet;
• removing the stylet;
• and
• inserting the conduit into the heart wall through the outer sleeve.

A method for advancing a device into the heart wall of a patient through a coronary artery, comprising:

• screwing a threaded device into the coronary artery to open the artery;
• pulling back on the artery;
• and
• screwing the threaded device into the heart wall.

A method of delivering a conduit into a heart wall between a heart chamber and an adjacent blood vessel, comprising:

• inserting a hollow needle into the heart wall through the blood vessel into the heart chamber;
• inserting a guidewire through the hollow needle into the heart chamber;
• removing the hollow needle;
• inserting a dilator over the guidewire into the heart wall;
• removing the guidewire;
• and
• screwing a threaded conduit over the dilator into the heart wall.

A method of providing direct blood flow between a heart chamber and a coronary vessel, the method comprising:

• placing a guide device through an anterior wall and a posterior wall of the coronary vessel and through a heart wall between the heart chamber and the coronary vessel;
• forming a passageway in the heart wall at a location defined by the guide device by inserting a dilator over the guide device at the location;
• and
• placing a conduit within the passageway,
• wherein the conduit is positioned over the dilator for placement within the passageway.

A method of providing direct blood flow between a heart chamber and a coronary vessel, the method comprising:

• placing a guide device through an anterior wall and a posterior wall of the coronary vessel and through a heart wall between the heart chamber and the coronary vessel;
• forming a passageway in the heart wall at a location defined by the guide device;
• and
• placing a conduit within the passageway by screwing the conduit into the heart wall.

A method of providing direct blood flow between a heart chamber and a coronary vessel, the method comprising:

• positioning a guide device external to the coronary vessel and moving a distal tip of the guide device toward an external surface of an anterior wall of the coronary vessel;
• placing the guide device through at least one wall of the coronary vessel and through a heart wall between the heart chamber and the coronary vessel;
• forming a passageway in the heart wall at a location defined by the guide device by inserting a dilator over the guide device at the location;
• and
• placing a conduit within the passageway,
• wherein the conduit is positioned over the dilator for placement within the passageway.
