Abstract
An electrode assembly for use in interventricular cardiac mapping includes one or more elongated splines each of which carries a plurality of spaced apart electrodes thereon. The body of each spline is formed of a plurality of alternating electrically conductive layers and the electrically non-conductive layers. A separate electrically conductive pathway is provided to connect each of the electrodes to a different one of the conductive layers. Each of the layers is electrically connected to an electrical signal processing device so that signals provided by each of the electrodes can be processed.

An apparatus for performing an endocardial procedure, comprising:
- a flexible catheter having a proximal end and a distal end;
- and
- a mapping assembly, the mapping assembly including a plurality of flexible electrode supports, each electrode support having a proximal end and a distal end, wherein the electrode supports are connected at their proximal ends to the catheter and at their distal ends to each other,
- wherein one of the electrode supports is pre-formed to collapse in response to an external force and to assume a single, prescribed final configuration upon the removal of the external force, the pre-formed electrode support having a generally rectangular cross-section and substantially flat surface having a plurality of substantially flat electrodes disposed thereon.
