1. A method of treating a hollow anatomical structure (HAS) of a patient, the method comprising:
- percutaneously accessing the HAS;
advancing a bioabsorbable fibrous body into the HAS in a downstream direction from the percutaneous access site, the body comprising;
a plurality of loose, non-knit and non-woven fibers, each fiber being bulked in a generally radial direction, extending in a generally longitudinal direction, having a number of bends along the length thereof such that in a first state each fiber has a shorter length and a greater width than in a second state, each fiber also being formed from one or more bioabsorbable materials, the fibers having a first bioabsorption rate; and
a bioabsorbable tether coupled to the fibrous body at a distal portion of the fibrous body, the tether extending longitudinally from the distal portion and along and substantially parallel to the fibrous body, the tether having a second bioabsorption rate that is different from the first bioabsorption rate;
implanting the bioabsorbable fibrous body in the HAS such that a proximal portion of it, including a proximal portion of the tether, extends through and out of the HAS and the percutaneous access site to terminate outside the patient'"'"'s body;
uncompressing and expanding the bioabsorbable fibrous body through self-expansion of individual fibers by moving individual fibers to the first state from the second state in which individual fibers have a shorter length and a greater width than in the second state on account of each fiber having a number of bends along the length thereof; and
occluding the HAS.

Abstract
A method of treating a vein comprises accessing a vein at an access point spaced from a sapheno-femoral junction. A bioabsorbable fibrous body is implanted into the vein through the access point. The body is moved in the vein toward the sapheno-femoral junction.

11. A method of treating a hollow anatomical structure (HAS) of a patient, the method comprising:
- implanting a bioabsorbable fibrous body in the HAS through an access site on the patient'"'"'s skin, the body comprising;
a plurality of loose, non-knit and non-woven fibers, each fiber being bulked in a generally radial direction, and extending in a generally longitudinal direction, having a number of bends along the length thereof such that, in an at-rest state, each fiber has a shorter length and a greater width than in a compressed state, each fiber also being formed from one or more bioabsorbable materials;
a bioabsorbable tether coupled to the fibrous body at a distal portion of the fibrous body, the tether extending longitudinally from the distal portion and along and substantially parallel to the fibrous body within the HAS after implantation;
the plurality of fibers being formed into an elongate bundle of fibers, the bundle being folded back along its longitudinal axis to form the fibrous body; and
positioning the fibrous body so that a proximal portion of it, including a proximal portion of the tether extends through and out of the HAS and the access site to terminate outside the patient'"'"'s body;
uncompressing and expanding the bioabsorbable fibrous body through self-expansion of individual fibers by moving individual fibers to the at-rest state from the compressed state such that the individual fibers have a shorter length and a greater width in the at-rest state than in the compressed state on account of each fiber having a number of bends along the length thereof;
occluding the HAS. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)

wherein the fibers include abrasive outer surfaces to enhance frictional contact between the fibers and the patient'"'"'s tissue;
