Abstract
Medical catheters with splined internal walls are disclosed as having sufficient rigidity to transmit torque from the proximal end to the distal end even over the long distances required for angioplast procedures. The splined geometry obviates the need for mesh layers characteristic of prior art guiding or diagnostic catheters and thus are significantly narrower and less costly to produce.
