Claim:
1. An apparatus for penetrating a vessel occlusion, comprising: a catheter comprising an attachment lumen extending in a non-parallel direction relative to a longitudinal axis of the catheter and configured to permit slidable insertion therethrough of a guidewire, said catheter further comprising a catheter cap located at a distal end of said catheter, said attachment lumen contained within said catheter cap, wherein said attachment lumen comprises a flexible tube attached at a distal end to a distal tip of said catheter cap and attached at a proximal end to said catheter, wherein movement of said guide wire relative to the attachment lumen generates friction forces between the attachment lumen and said guide wire to reversibly couple said guide wire to said catheter, said coupling being acceleration force-specific.
