Abstract
A system for sensing multiple local electric voltages from endocardial surface of a heart, includes: an elongate tubular member having a lumen, a proximal end and a distal end; a plurality of flexible splines; an anchor for securably affixing the proximal portions of the splines, where the anchor is securably affixed within the lumen of the elongate tubular member at the distal end of the elongate tubular member; and a metallic tip for securably affixing the distal portions of the splines.

-31. (canceled)
A device for insertion into a body lumen, comprising:
- an electrode assembly strip comprising:
- a polymeric substrate having an upper surface and an opposed lower surface;
- one or more electrodes disposed over a portion of the upper surface of the polymeric substrate;
- and
- one or more electrical traces disposed over a portion of the lower surface of the polymeric substrate in electrical communication with the one or more electrodes by way of metal plated holes through the substrate;
- and
- a polymeric member having an outer surface and a substrate wall;
- wherein the electrode assembly strip is securably disposed at the outer surface of the polymeric member.
A device for insertion into a body lumen, comprising:
- an elongate tubular member having a lumen, a proximal end and a distal end;
- at least two flexible splines having proximal portions, distal portions and medial portions therein between;
- an anchor for guiding the proximal portions of the splines into the lumen of the elongate tubular member at the distal end of the elongate tubular member;
- a tip for receiving the distal portions of the splines;
- and
- an electrode assembly disposed over at least one of the splines.
A device for insertion into a body lumen, comprising:
- an elongate tubular member having a lumen, a proximal end and a distal end;
- at least one flexible spline having opposed spline ends and a medial portion therein between;
- an anchor for guiding proximal portions of the spline near the spline ends into the lumen of the elongate tubular member at the distal end of the elongate tubular member;
- a tip for receiving the medial portion of the spline;
- a polymeric tube disposed over a portion of the spline;
- and
- an electrode assembly disposed over a portion of the polymeric tube.
