Abstract
A device and method for treating a patient with total or near total occlusion is provided. The device can be positioned in a blood vessel at a treatment site. An occlusion at the treatment site is enlarged by a catheter. The catheter can be advanced over a guidewire into the occlusion. One or more of [a] compression or torsion applied to the guidewire or [b] compression or torsion applied to the catheter body expands or creates a path through the occlusion. The expansions or creation of the access path can be by cutting or abrading the occlusion or by a shoe-horn effect.
