ABSTRACT:
A spiral catheter apparatus and method of use for access to, and laser or other treatment within, cavities and organs in the human body, the apparatus having a spiral member with a selected curvilinear shape, but flexible enough to assume a temporarily elongated shape such that the spiral member can be extended through the vasculature in the temporarily elongated shape and will assume the selected curvilinear shape when extended into a body cavity or organ, the spiral member formed of a superelastic or other material, the selected curvilinear shape serving to securely position the spiral member adjacent a selected surface within the body cavity or organ for laser or other treatment with a laser delivery device or other functional device on a selected surface, the apparatus further having a main catheter shaft with at least two hollow lumens extending therethrough, the first lumen for slidably guiding the main catheter shaft over the spiral member into a first position adjacent the selected surface, and the second lumen having a guide hole adjacent the distal end of the main catheter shaft for advancing a laser delivery device or other functional device through the guide hole for laser or other treatment on the selected surface within the body cavity or organ.
