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

A method of treating a body lumen having a pathologic occlusion at least partially occluding flow of body fluid from flowing proximally from said pathologic occlusion to locations distal to said pathologic occlusion, comprising:
- obstructing said lumen with a conformal artificial occlusion distal to said pathologic occlusion;
- ablating said pathologic occlusion to create a plurality of emboli of said pathologic occlusion on a proximal side of said artificial occlusion;
- removing said emboli from said lumen;
- removing said artificial occlusion.
An apparatus for treating a body lumen having a pathologic occlusion at least partially occluding flow of body fluid from flowing proximally from said pathologic occlusion to locations distal to said pathologic occlusion, comprising:
- a delivery member sized to be passed through said body lumen proximal to said pathologic occlusion and having a distal end adapted to be passed through said pathologic occlusion to a position distal to said pathologic occlusion;
- said delivery member including a delivery port adjacent said distal end for delivery of a artificial occlusion into said lumen distal to said pathologic occlusion.
A kit for treating a body lumen having a pathologic occlusion at least partially occluding flow of body fluid from flowing proximally from said pathologic occlusion to locations distal to said pathologic occlusion, comprising:
- an occlusion-creating member for obstructing said lumen with a material creating a conformal artificial occlusion distal to said pathologic occlusion;
- an ablator for ablating said pathologic occlusion to create a plurality of emboli of said pathologic occlusion on a proximal side of said artificial occlusion;
- an emboli-removing member for removing said emboli from said lumen.
A method of treating a first blood vessel defining a first lumen having a pathologic occlusion at least partially occluding flow of blood from flowing proximally from said pathologic occlusion to locations distal to said pathologic occlusion and wherein a second blood vessel having a second lumen resides adjacent said first blood vessel distal to said pathologic occlusion, comprising:
- advancing a first member through said second lumen to a position adjacent said first vessel distal to said pathologic 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 pathologic occlusion;
- ablating said pathologic occlusion to create a plurality of emboli of said pathologic occlusion on a proximal side of said artificial occlusion;
- removing said emboli from said lumen;
- removing said artificial occlusion.
A method of treating a first blood vessel defining a lumen having a pathologic occlusion at least partially occluding flow of blood from flowing proximally from said pathologic occlusion to locations distal to said pathologic occlusion, comprising:
- advancing a compression member to a position adjacent an exterior of said vessel distal to said pathologic 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 pathologic occlusion;
- ablating said pathologic occlusion to create a plurality of emboli of said pathologic occlusion on a proximal side of said artificial occlusion;
- removing said emboli from said lumen;
- removing said artificial occlusion by removing said compression member.

- removing said artificial occlusion.
A method of treating a body lumen at a treatment site, said body lumen having a body fluid flowing from proximal said treatment site to locations distal to said treatment site, said method comprising:
- obstructing said lumen with an artificial occlusion distal to said treatment site;
- treating said lumen on a proximal side of said artificial occlusion;
- removing said artificial occlusion by dissolving said artificial occlusion within said body fluid after said treating.
A method of treating a body lumen at a treatment site, said body lumen having a body fluid flowing from proximal said treatment site to locations distal to said treatment site, said method comprising:
- obstructing said lumen with an artificial occlusion distal to said treatment site, wherein said obstructing is achieved by injecting a material, selected to form said artificial occlusion, from a delivery member into said lumen;
- treating said lumen on a proximal side of said artificial occlusion;
- removing said artificial occlusion.
A method of treating a body lumen at a treatment site, said body lumen having a body fluid flowing from proximal said treatment site to locations distal to said treatment site, said method comprising:
- obstructing said lumen with an artificial occlusion distal to said treatment site, wherein said artificial occlusion is formed from a flowable material;
- treating said lumen on a proximal side of said artificial occlusion;
- removing said artificial occlusion.
A method of blocking a body lumen, the body lumen having a body fluid flowing therethrough, said method comprising:
- providing a flowable material within said lumen, wherein said flowable material expands within said lumen to block body fluid flowing through said lumen.
