Accessing, implant anchoring, and visualization during coronary artery bypass graft

A method for performing cardiac artery bypass grafting, the method comprising:

• navigating a catheter to a ventricle of a patient;
• puncturing through a ventricular wall into a targeted vessel with a blockage;
• and
• implanting a shunt between the ventricle and the targeted vessel such that the shunt is downstream of the blockage and the shunt enables passage of blood from the ventricle to the targeted vessel.

A method for performing cardiac artery bypass grafting, the method comprising:

• navigating a catheter to a first coronary artery of a patient;
• puncturing through the first coronary artery of the patient;
• navigating the catheter to a second coronary artery of the patient, the second coronary artery including a blockage;
• and
• implanting a shunt from the first coronary artery of the patient to the second coronary artery of the patient, the shunt being anchored to the second coronary artery of the patient downstream of the blockage.

A method for performing cardiac artery bypass grafting, the method comprising:

• navigating a catheter within a targeted vessel of a patient, the targeted vessel including a blockage, the catheter navigated to a position upstream of the blockage;
• puncturing through the targeted vessel with the catheter;
• navigating the catheter outside the targeted vessel to a point downstream of the blockage;
• and
• re-entering the targeted vessel with the catheter downstream of the blockage.

A method for performing cardiac artery bypass grafting, the method comprising:

• navigating a catheter to a targeted vessel of a patient, the targeted vessel including a blockage, the catheter navigated to a position downstream of the blockage;
• anchoring an implant to the targeted vessel, the implant including anchors at a distal end of the implant configured to secure to the targeted vessel;
• and
• creating a passageway from the implant to the targeted vessel to enable blood flow in the targeted vessel downstream of the blockage.

A method for performing cardiac artery bypass grafting, the method comprising:

• navigating a catheter to a targeted vessel of a patient, the targeted vessel including a blockage, the catheter navigated to a position downstream of the blockage;
• anchoring a supply line that is partially embedded in a cardiac wall and partially embedded in the targeted vessel, the supply line having a diameter greater than a diameter of the targeted vessel;
• and
• seeding angiogenesis due at least in part to the anchored supply line to provide blood flow in the targeted vessel downstream of the blockage.
