Abstract
Official abstract text for this publication.
A catheter comprising an elongated catheter body, and an electrode assembly distal of the catheter body, the assembly comprising a plurality of spines, wherein each spine has a distal end that is connected to the distal end of at least one other spine, wherein each spine has an electrode-carrying portion, the electrode-carrying portions of all spines of the assembly being in a single common plane, and wherein all spines of the assembly have a uniform exposed total length.
First claim
Opening claim text (preview).
What is claimed is: 1. A catheter comprising: an elongated catheter body; and an electrode assembly distal of the catheter body, the assembly comprising a plurality of spines, wherein the plurality of spines includes at least three spines, wherein each spine has a distal end that is connected to the distal end of at least one other spine, wherein each spine has an electrode-carrying portion, the electrode-carrying portions of all spines of the assembly being in a single common plane, wherein all spines of the assembly have a uniform exposed total length, wherein the electrode-carrying portions are linear, and wherein the electrode-carrying portions are parallel with a longitudinal axis of the catheter. 2. The catheter of claim 1 , wherein the electrode-carrying portions are parallel with each other. 3. The catheter of claim 1 , wherein the assembly has longitudinal symmetry. 4. The catheter of claim 1 , wherein each spine has a mirror counterpart spine. 5. The catheter of claim 1 , wherein each spine has a nonconductive covering. 6. The catheter of claim 1 , wherein each spine has at least one ring electrode. 7. The catheter of claim 1 , wherein each spine has at least one irrigated ring electrode. 8. The catheter of claim 1 , wherein the plurality of spines includes less than eight spines. 9. The catheter of claim 1 , wherein the plurality of spines includes less than six spines. 10. A catheter comprising: an elongated catheter body; and an electrode assembly distal of the catheter body, the assembly comprising a plurality of spines, wherein the plurality of spines includes at least three spines, wherein each spine has a distal end that is connected to the distal end of at least one other spine, wherein each spine has an electrode-carrying portion, the electrode-carrying portions of all spines of the assembly being in a single common plane, wherein all spines of the assembly have a uniform exposed total length, and wherein each spine has at least a divergent proximal portion. 11. The catheter of claim 10 , wherein at least one spine has a convergent proximal portion that is distal of the divergent proximal portion. 12. A catheter comprising: an elongated catheter body; and an electrode assembly distal of the catheter body, the assembly comprising a plurality of spines, wherein the plurality of spines includes at least three spines, wherein each spine has a distal end that is connected to the distal end of at least one other spine, wherein each spine has an electrode-carrying portion, the electrode-carrying portions of all spines of the assembly being in a single common plane, wherein all spines of the assembly have a uniform exposed total length, and wherein each spine has at least a convergent distal portion. 13. The catheter of claim 12 , wherein at least one spine has a divergent distal portion that is proximal of the convergent distal portion.
