Claim Text:
1. A system for sensing monophasic action potentials from endocardial tissue of a heart, comprising: a first elongate tubular member having a lumen, a proximal end and a distal end; a basket assembly comprising: wherein the flexible electrode assembly strip comprises: wherein at least one of the two or more exposed electrodes is disposed over at least part of the outer surface of the polymeric member which is adjacent to the outer surface of the spline and the other of the two or more exposed electrodes is disposed over at least another part of the outer surface of the polymeric member which is adjacent to the inner surface of the spline; wherein the first opposed open end of the polymeric member is disposed at the distal spline portion of said at least one of the plurality of flexible splines at a position near to the distal tip and the second opposed open end of the polymeric member is secured to the proximal spline portion of said at least one of the plurality of flexible splines at a position near to the anchor; wherein medial portions of the polymeric member between said first opposed open end and said second opposed open end of the polymeric member are not secured to said medial portions of said at least one of the plurality of flexible splines; wherein the basket assembly has a radially expanded non-cylindrical shape; and wherein the splines comprise a superelastic material.
