23. A method for removing an occlusion from a tubular structure, where the tubular structure comprises a proximal end, a distal end, and intermediate segment and a central lumen within the intermediate segment, and where the occlusion is within the central lumen, the method comprising:
-
a) providing means for removing an occlusion from within the central lumen of a tubular structure, where the means for removing an occlusion comprises a proximal end and a distal end, and comprises an occlusion removing structure having a low profile configuration and having a high profile configuration;
b) inserting the distal end of the means for removing an occlusion into the proximal end of the tubular structure in the low profile configuration;
c) advancing the means for removing an occlusion through the central lumen of the tubular structure until the distal end of the means for removing an occlusion is at least partly distal to the occluding material;
d) converting the occlusion removing structure into the high profile configuration; and
e) withdrawing the means for removing an occlusion from the tubular structure while the occlusion removing structure is in the high profile configuration, thereby removing some or all of the occluding material from the tubular structure. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31)
