Abstract
This invention relates to occlusion of a hollow anatomical structure by inserting an occluding device or occluding material into a hollow anatomical structure or surrounding native tissue.
Claims61
A method for occluding a hollow anatomical structure in a patient, the method comprising:
- reducing an interior cross-sectional area of the hollow anatomical structure by applying a vacuum to an interior of the hollow anatomical structure;
- and
- placing an occluding material at an occlusion site, whereby an occlusion is formed in the hollow anatomical structure.
A method for occluding a hollow anatomical structure in a patient, the method comprising:
- placing an occluding material at an occlusion site, whereby an occlusion is formed in the hollow anatomical structure;
- wherein the hollow anatomical structure is a vein, and wherein placing an occluding material at the site comprises placing a material in a perivenous space surrounding the vein at the occlusion site, whereby an occlusion is formed in the vein;
- wherein the material is shrinkable, and wherein an occlusion is formed in the vein by shrinking the material.
A method for occluding a hollow anatomical structure in a patient, the method comprising:
- placing an occluding material at an occlusion site, whereby an occlusion is formed in the hollow anatomical structure;
- wherein the hollow anatomical structure is a vein, and wherein placing an occluding material at the site comprises placing a material in a perivenous space surrounding the vein at the occlusion site, whereby an occlusion is formed in the vein;
- wherein the material is an alpha-hydroxy acid.
A method for occluding a hollow anatomical structure in a patient, the method comprising:
- placing an occluding material at an occlusion site, whereby an occlusion is formed in the hollow anatomical structure;
- wherein the hollow anatomical structure is a vein, and wherein placing an occluding material at the site comprises placing a material in a perivenous space surrounding the vein at the occlusion site, whereby an occlusion is formed in the vein;
- wherein the material is collagen.
