1. A conforming cardiac mapping electrode set assembly, comprising:
- a pliable electrically insulative mounting cup having electrodes mounted therein, said electrodes being exposed on an electrically insulative administration surface of the pliable mounting cup for conforming contact with cardiac tissue, said pliable mounting cup having a shape that is variable between a concave orientation of the administration surface and a convex orientation of the administration surface;
a trunk portion generally centrally disposed with respect to said pliable mounting cup, said trunk portion having a cable depending therefrom;
an insulated wire connected to each said electrode, each said insulated wire passing through said generally centrally disposed trunk portion and through said cable, said insulated wires being insulated from each other; and
said electrodes of said pliable mounting cup being controllably movable with said pliable electrically insulative mounting cup to provide an array of electrodes on the electrically insulative administration surface that is conformable to a convex surface of the cardiac tissue and that is also conformable to a concave surface of the cardiac tissue.

Abstract
A set of electrodes are provided, preferably in a symmetrical array, which electrodes are mounted within a pliable mounting cup that is capable of conforming to the shape and size of various surfaces of body organs, such as the heart. The pliable cup is capable of both epicardial and endocardial types of mapping procedures, each electrode being connected to a thin insulated wire that joins similar wires in a generally centrally located trunk portion of the cup, and a cable containing the thus bundled wires depends from the trunk portion for connection to a suitable data display and/or recording system.
