Abstract:
1. A system for sensing multiple local electric voltages from endocardial surface 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: a polymeric substrate having an inner surface and an opposed outer surface; said one or more exposed electrodes disposed over at least part of the outer surface of the polymeric substrate; and one or more electrical traces disposed over at least a portion of the inner surface of the polymeric substrate or over at least a portion of the outer surface of the polymeric substrate, said one or more electrical traces being in electrical communication with said one or more exposed electrodes; 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.
