Abstract
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 Analysis
Total Claims: 26
Claim 1
Independent Claim
149 words
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.
Claim 2
Independent Claim
149 words
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.

Claim 4
Dependent Claim
36 words
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.
Claim 5

Claim 6
Dependent Claim
20 words
The method of claim 1, further comprising the step of removing a portion of a pericardium associated with the heart.
Claim 7
Dependent Claim
20 words
The method of claim 3, further comprising the step of determining if a blood clot is present at the passage.
Claim 8
Dependent Claim
19 words
The method of claim 4, further comprising the step of determining if a clot is present at the passage.
Claim 9
Independent Claim
165 words
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.
Claim 10
Independent Claim
165 words
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.
