Abstract
Abstract A method for performing a procedure at the fossa ovalis in the septal wall of the heart includes the steps of providing a sheath having a body wherein the body has a lumen extending therethrough and an open end at the distal end of the body. The body also has at least one electrode and a position sensor at the distal end of the body. The position sensor generates signals indicative of the location of the distal end of the body. The sheath is navigated to the septal wall using the position sensor and the fossa ovalis in the septal wall is identified using the at least one electrode of the sheath.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
143 words
A method for performing a procedure at a fossa ovalis in a septal wall of a heart, the method comprising the steps of: providing a sheath comprising a body, the body having a lumen extending therethrough and an open end at a distal end of the body, the body also having at least one electrode and a position sensor at the distal end of the body, the position sensor generating signals indicative of a location of the distal end of the body; navigating the sheath to the septal wall using the position sensor; reconstructing an electroanatomical map using the at least one electrode and the position sensor of the sheath; identifying the fossa ovalis in the septal wall using the at least one electrode and the position sensor of the sheath; and displaying the fossa ovalis as a tagged point on the map.
Claim 2
Independent Claim
143 words
A method for performing a procedure at a fossa ovalis in a septal wall of a heart, the method comprising the steps of: providing a sheath comprising a body, the body having a lumen extending therethrough and an open end at a distal end of the body, the body also having at least one electrode and a position sensor at the distal end of the body, the position sensor generating signals indicative of a location of the distal end of the body; navigating the sheath to the septal wall using the position sensor; reconstructing an electroanatomical map using the at least one electrode and the position sensor of the sheath; identifying the fossa ovalis in the septal wall using the at least one electrode and the position sensor of the sheath; and displaying the fossa ovalis as a tagged point on the map.
Claim 3
Dependent Claim
24 words
The method according to claim 1 , further comprising identifying the fossa ovalis based on injury patterns detected using the at least one electrode.
Claim 4
Dependent Claim
43 words
The method according to claim 2 , further comprising identifying the fossa ovalis by determing an injury pattern for an area on the septal wall that exhibits less of an injury pattern than injury patterns exhibited by other areas on the septal wall.
Claim 5
Dependent Claim
15 words
The method according to claim 3 , further comprising detecting injury patterns using injury curves.
Claim 6
Dependent Claim
15 words
The method according to claim 4 , further comprising detecting injury patterns with an electrocardiogram.
Claim 7
Dependent Claim
19 words
The method according to claim 5 , further comprising displaying the injury patterns in the form of PQRST waves.
Claim 8
Dependent Claim
28 words
The method according to claim 2 , further comprising identifying the fossa ovalis by finding an area on the septal wall that does not exhibit an injury pattern.
Claim 9
Dependent Claim
21 words
The method according to claim 1 , further comprising determining the location coordinates of the tagged point using the position sensor.
Claim 10
Dependent Claim
24 words
The method according to claim 8 , further comprising determining the location coordinates of the tagged point by identifying position coordinates of the point.
Claim 11
Dependent Claim
16 words
The method according to claim 9 , further comprising identifying orientation coordinates for the tagged point.
Claim 12
Dependent Claim
20 words
The method according to claim 1 , further comprising tagging the point at the fossa ovalis with a physical tag.
Claim 13
Dependent Claim
20 words
The method according to claim 11 , further comprising tagging the point at the fossa ovalis using an active tag.
Claim 14
Dependent Claim
20 words
The method according to claim 11 , further comprising tagging the point at the fossa ovalis using a passive tag.
Claim 15
Dependent Claim
13 words
The method according to claim 1 , further comprising perforating the fossa ovalis.
Claim 16
Dependent Claim
28 words
The method according to claim 14 , further comprising perforating the fossa ovalis by extending a penetrating device through the lumen and the distal end of the sheath.
Claim 17
Dependent Claim
16 words
The method according to claim 15 , further comprising withdrawing the penetrating device from the sheath.
Claim 18
Dependent Claim
28 words
The method according to claim 16 , further comprising extending a secondary device through the sheath and the fossa ovalis and into the left atrium of the heart.
Claim 19
Dependent Claim
21 words
The method according to claim 17 , further comprising performing a diagnostic procedure in the left atrium with the secondary device.
Claim 20
Dependent Claim
21 words
The method according to claim 17 , further comprising performing a therapeutic procedure in the left atrium with the secondary device.
