Abstract

A method for operating on a heart is described. The method is directed to closing the passage between an atrium and its associated atrial appendage or completely removing the appendage. The method is structured to permit manipulation of the appendage without severing the sternum or ribs of the patient being operated upon. Rather, openings are made between the ribs to provide access to the heart for observation with a thoroscope and manipulation with appropriate surgical instruments.

Claims

1. A method for manipulating tissue of the heart, where the heart is located within a chest cavity defined by a sternum and an associated set of ribs and the heart includes an atrium and atrial appendage having a fluid passage therebetween, the method comprising the steps of:

a) inserting an observation device into the chest cavity to permit observation of heart tissue from the exterior of the chest cavity, where the device is inserted at a first position between two ribs;

b) inserting a manipulation device into the chest cavity to permit operation on heart tissue from the exterior of the chest cavity, where the device is inserted at a second position between two ribs;

c) positioning the manipulation device substantially proximate a selected tissue area of the heart and operating on the selected tissue; and

d) maintaining the sternum and ribs intact during the execution of steps a-c.

2. The method of claim 1, where the selected tissue is the atrial appendage, and the method further comprise the step of removing the appendage from the heart.

3. The method of claim 1, where the selected tissue is an atrial appendage, and the method further comprise the steps of sewing the appendage at the passage with its associated atrium to prevent blood flow therebetween.

4. The method of claim 1, where the selected tissue is an atrial appendage, and the method further comprises the step of stapling the appendage at the passage to prevent blood flow therebetween.

5. The method of claim 1, further comprising the step of removing a portion of a pericardium associated with the heart.

6. The method of claim 3, further comprising the step of determining if a blood clot is present at the passage.

7. The method of claim 4, further comprising the step of determining if a clot is present at the passage.

8. A method for eliminating a passage for blood flow located between the left atrium of a heart and the left atrial appendage, where the heart is located within a chest cavity defined by a sternum and an associated set of ribs, the method comprising the steps of:

a) inserting an observation device into the chest cavity to permit observation of heart tissue from the exterior of the chest cavity, where the device is inserted at a first position between two ribs;

b) inserting a manipulation device into the chest cavity to permit manipulation of heart tissue from the exterior of the chest cavity, where the device is inserted at a second position between two rib;

c) positioning the manipulation device substantially proximate the passage for blood flow located between the left atrium and the left atrial appendage;

d) manipulating the atrial appendage such that the passage for blood flow is closed; and

e) maintaining the sternum and ribs intact during the execution of steps a-d.

9. The method of claim 8, further comprising the step of removing the atrial appendage.

10. The method of claim 9, further comprising the step of inserting a device for directing laser energy into the chest cavity where the atrial appendage is removed.

11. The method of claim 8, where the step of manipulating the atrial appendage includes sewing shut the passage for blood flow.

12. The method of claim 8, where the step of manipulating the atrial appendage includes the step of stapling shut the passage for blood flow.

13. The method of claim 8, further comprising the step of removing a portion of a pericardium associated with the heart.

14. The method of claim 11, further comprising the step positioning a probe to determine if a clot is present at the location of blood flow.

15. The method of claim 12, further comprising the step positioning a probe to determine if a clot is present at the location of blood flow.

16. A method for eliminating a passage for blood flow located between the left atrium of a heart and the left atrial appendage, where the heart is located within a chest cavity of a patient, where the cavity is defined by a sternum and an associated set of ribs, the method comprising the steps of:

a) applying a general anesthetic to the patient;

b) collapsing the left lung of the patient;

c) making a first opening into the chest cavity at a first location between two ribs;

d) extending a thoroscope into the first opening and orienting the thoroscope in a position to observe the left atrial appendage and surrounding heart tissue;

e) making a second opening into the chest cavity at a second location between two ribs;

f) inserting a manipulation device into the second opening to permit manipulation of heart tissue from the exterior of the chest cavity;

g) positioning the manipulation device substantially proximate the passage for blood flow located between the left atrium and the left atrial appendage;

h) manipulating the atrial appendage such that the passage for blood flow is closed; and

i) maintaining the sternum and ribs intact during the execution of steps a-h.

17. The method of claim 16, where the step of manipulating the atrial appendage includes removing the appendage.

18. The method of claim 17, further comprising the step of inserting a device for directing laser energy into the chest cavity to bleeding.

19. The method of claim 16, where the step of manipulating the atrial appendage includes sewing shut the passage for blood flow.

20. The method of claim 16, where the step of manipulating the atrial appendage includes stapling shut the passage for blood flow.

21. The method of claim 16, further comprising the step of removing a portion of a pericardium associated with the heart.

22. The method of claim 19, further comprising the step positioning a probe to determine if a clot is present at the location of blood flow.

23. The method of claim 20, further comprising the step positioning a problem to determine if a clot is present at the location of blood flow.
