Abstract
A dual lumen guidewire support catheter for accurately crossing a chronic total occlusion in a vessel is disclosed. The dual lumen guidewire support catheter includes a first lumen portion and a second lumen portion sharing a common side and a common distal end. The first lumen portion can be a rapid exchange or over-the-wire portion, while the second lumen portion is an over the wire portion. One or both of the portions can include a discontinuity to enable removal of a guidewire following placement through or at an occlusion or lesion.
