ABSTRACT:
A catheter and catheter device for accessing a target site along a tortuous, small-vessel pathway. The catheter includes a flexible distal segment which is composed of a flexible outer tube and a low-friction surface structure embedded in the polymer tube and forming hard, disjoint surface regions. The surface structure allows the catheter to be advanced over sharp bends and small-diameter loops in a guide wire, in advancing the catheter along a small-vessel pathway.
