METHOD OF CARDIAC SURGERY, AND DEFIBRILLATION ELECTRODE, DEFIBRILLATOR, AND ENDOSCOPE APPARATUS FOR THE SAME
First Claim
1. A method of cardiac surgery, comprising:
- using a device which comprises a treatment unit to be inserted into a thoracic cavity for performing treatment of a heart;
inserting a distal end of this device between the heart and a pericardium;
thereafter piercing through the pericardium with the distal end of said device; and
performing treatment of the heart from the outside of the pericardium by using the treatment unit.

Abstract
To provide a method of cardiac surgery which is capable of facilitating the manipulation of devices in a thoracic cavity so as to thereby simplify the surgery, as well as alleviating physical burdens on a patient, and a defibrillation electrode, a defibrillator, and an endoscope apparatus for the same. There is provided a method of cardiac surgery, comprising: using a device which comprises a treatment unit to be inserted into a thoracic cavity for performing treatment of a heart; inserting a distal end of this device between the heart and a pericardium; thereafter piercing through the pericardium with the distal end of the device; and performing treatment of the heart from the outside of the pericardium by using the treatment unit.

8. A method of cardiac surgery, comprising:
- inserting a lead wire of a defibrillator between a pericardium and a heart;
thereafter piercing through said pericardium with the distal end of the lead wire; and
placing an electrode provided on the distal end of said lead, outside the pericardium.
- inserting a lead wire of a defibrillator between a pericardium and a heart;

9. A method of cardiac surgery, comprising:
- inserting a device for bypassing a coronary artery with use of an internal thoracic artery as a graft, between a heart and a pericardium;
thereafter piercing through said pericardium with the distal end of the device to thereby introduce the device to said internal thoracic artery;
separating said internal thoracic artery; and
connecting the ends of said internal thoracic artery to the coronary artery.
- inserting a device for bypassing a coronary artery with use of an internal thoracic artery as a graft, between a heart and a pericardium;
-
10. A defibrillation electrode, comprising:
-
an electrode portion to be placed along a surface of a pericardium; a lead wire which is connected to the electrode portion for piercing through the pericardium; and a stopper which is provided on the lead wire to be placed in a vicinity of the pierced part of the pericardium in a state where said electrode portion is placed on the surface of the pericardium, and then projected radially outward from the lead wire to limit a longitudinal movement of the lead wire. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19)
