Claims Analysis
Total Claims: 25
Claim 1
Independent Claim
135 words
A procedure for the diagnosis or treatment of atrial flutter or atrial fibrillation in the right atrium of the heart comprising (a) introducing into a specific location in the right atrium a guiding introducer with a predetermined shape containing a lumen running lengthwise therethrough, a proximal and a distal end, (b) introducing into the lumen of the guiding introducer an ablating or mapping catheter containing a proximal and distal end, wherein said catheter has one or more electrodes located at or near the distal end of the catheter, (c) guiding the catheter to a selected location within the right atrium by use of the guiding introducer, and (d) mapping or ablating a selected location or track within the right atrium by use of the electrodes of the catheter to treat atrial flutter or atrial fibrillation.
Claim 2
Dependent Claim
135 words
A procedure for the diagnosis or treatment of atrial flutter or atrial fibrillation in the right atrium of the heart comprising (a) introducing into a specific location in the right atrium a guiding introducer with a predetermined shape containing a lumen running lengthwise therethrough, a proximal and a distal end, (b) introducing into the lumen of the guiding introducer an ablating or mapping catheter containing a proximal and distal end, wherein said catheter has one or more electrodes located at or near the distal end of the catheter, (c) guiding the catheter to a selected location within the right atrium by use of the guiding introducer, and (d) mapping or ablating a selected location or track within the right atrium by use of the electrodes of the catheter to treat atrial flutter or atrial fibrillation.
