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.
Claims58
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.
A method according to claim 3 wherein said artificial occlusion is removed without substantial creation of permanent emboli.
An apparatus for 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:
- a delivery member sized to be passed through said body lumen proximal to said natural occlusion and having a distal end adapted to be passed through said natural occlusion to a position distal to said natural occlusion;
- and
- said delivery member including a delivery port adjacent said distal end for delivery of an artificial occlusion into said lumen distal to said natural occlusion.
An apparatus according to claim 30 wherein said solvents are contained within said material and selectively activated therein.
A kit for 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:
- an occlusion-creating member for obstructing said lumen with a material creating a conformal artificial occlusion distal to said natural occlusion;
- an ablator for ablating said natural occlusion to create a plurality of emboli of said natural occlusion on a proximal side of said artificial occlusion;
- and
- 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 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.
