Catheter with transverse branches

Apparatus, comprising:

• a flexible insertion tube, having a distal segment that is configured to be inserted into a body organ;
• a plurality of elastic branches connected to the distal segment of the insertion tube at different, respective locations and extending transversely away from the insertion tube at the respective locations;
• one or more respective electrodes disposed on each of the elastic branches;
• and
• conductors traversing the elastic branches so as to couple the electrodes to the insertion tube;
• wherein for a cross-sectional circle of the flexible insertion tube only one of the elastic branches is connected to the circle;
• and
• wherein the elastic branches are orthogonal to the distal segment.
