Catheter support structure

摘要

A catheter has a support segment which includes a plurality of support struts. Each of the struts has first and second ends longitudinally spaced apart along a longitudinal axis of the segment. The struts curve at least partially around the axis from the first ends to the second ends. The support struts include a first set and a second set. The struts of the first set extend around the axis in a clockwise direction. The struts of the second set extend around the axis in a counter-clockwise direction.
