Abstract

An intra-cardiac mapping system is based on locating the ports through which blood flows in or out the heart chambers. For many procedures, such as ablation to cure atrial fibrillation, locating the pulmonary veins and the mitral valve accurately allows to perform a Maze procedure. The location of the ports and valves is based on using the convective cooling effect of the blood flow. The mapping can be performed by a catheter-deployed expandable net or a scanning catheter. The same net or catheter can also perform the ablation procedure.

First claim

What is claimed is:

1. A treatment system, comprising:
a structure;
a plurality of elements carried by the structure, the structure and the plurality of elements sized to be receivable in an intra-cardiac cavity of a heart, the intra-cardiac cavity formed at least in part by a tissue wall having an interior surface, the interior surface interrupted by one or more ports in fluid communication with the intra-cardiac cavity, each of the plurality of elements including at least one…
