1. A method of treating a body lumen having a natural occlusion at least partially occluding flow of body fluid from flowing proximally from said natural occlusion to locations distal to said natural occlusion, comprising:
- obstructing said lumen with a conformal artificial occlusion distal to said natural occlusion;
ablating said natural occlusion to create a plurality of emboli of said natural occlusion on a proximal side of said artificial occlusion;
removing said emboli from said lumen; and
removing said artificial occlusion.

Abstract
A method for treating a body lumen having a natural occlusion at least partially occluding a flow of body fluid in the lumen includes obstructing the lumen with an artificial occlusion distal to the natural occlusion. The natural occlusion is ablated in a process which may create a plurality of emboli of the natural occlusion on a proximal side of the artificial occlusion. The emboli are removed from the lumen and, subsequently, the artificial occlusion is removed.

58. A method of treating a first blood vessel defining a first lumen having a natural occlusion at least partially occluding flow of blood from flowing proximally from said natural occlusion to locations distal to said natural occlusion and wherein a second blood vessel having a second lumen resides adjacent said first blood vessel distal to said natural occlusion, comprising:
-
advancing a first member through said second lumen to a position adjacent said first vessel distal to said natural occlusion;
urging said member against a wall of the second vessel to impinge upon the first vessel urging said first vessel to form an artificial occlusion distal to said natural occlusion;
ablating said natural occlusion to create a plurality of emboli of said natural occlusion on a proximal side of said artificial occlusion;
removing said emboli from said lumen; and
removing said artificial occlusion.
