Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 106 words
A method of ablating tissue, comprising the steps of: providing an ablating device and a cover, the ablating device having a bottom surface, the cover being spaced apart from the bottom surface to define a fluid cavity, the fluid cavity containing a flowable material; positioning the cover against a tissue surface; moving the cover away from the bottom surface so that the bottom surface is exposed and positioned adjacent the tissue surface, the flowable material conforming to the shape of the tissue surface and being positioned between the bottom surface of the ablating device and the tissue surface; and ablating the tissue after the moving step.
Claim 2
Independent Claim 106 words
A method of ablating tissue, comprising the steps of: providing an ablating device and a cover, the ablating device having a bottom surface, the cover being spaced apart from the bottom surface to define a fluid cavity, the fluid cavity containing a flowable material; positioning the cover against a tissue surface; moving the cover away from the bottom surface so that the bottom surface is exposed and positioned adjacent the tissue surface, the flowable material conforming to the shape of the tissue surface and being positioned between the bottom surface of the ablating device and the tissue surface; and ablating the tissue after the moving step.
Claim 3
Dependent Claim 21 words
The method of claim 1 , wherein: the positioning step is carried out with the tissue surface being an epicardial surface.
Claim 4
Dependent Claim 26 words
The method of claim 1 , wherein: the moving step is carried out by moving the cover while substantially maintaining the position of the ablating device.
Claim 5
Dependent Claim 20 words
The method of claim 1 , wherein: the providing step is carried out with the cover having a removable tip.
Claim 6
Dependent Claim 27 words
The method of claim 1 , wherein: the providing step is carried out with the flowable material having a boiling temperature of at least 120 degrees C.
Claim 7
Dependent Claim 27 words
The method of claim 1 , wherein: the providing step is carried out with the flowable material being selected from the group consisting of PEG and glycerine.
Claim 8
Dependent Claim 23 words
The method of claim 1 , wherein: the providing step is carried out with the ablating device having a plurality of ablating elements.
Claim 9
Dependent Claim 23 words
The method of claim 1 , wherein: the providing and moving steps are carried out with the ablating device forming a closed loop.
Claim 10
Dependent Claim 42 words
The method of claim 8 , wherein: the providing and moving steps are carried out with the ablating device forming a closed loop around the pulmonary veins; and the ablating step is carried out to form an ablation around the pulmonary veins.
