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.

16. 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; 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 a bioabsorbable tether coupled to the fibrous body at least 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; 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; controlling a lengthening of the fibrous body after implantation using the tether; and occluding the HAS. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26)

27. 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 least 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; and occluding the HAS. - View Dependent Claims (28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38)

39. 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; 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 a bioabsorbable tether coupled to the fibrous body at least 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; 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, wherein the fibers include abrasive outer surfaces to enhance frictional contact between the fibers and the patient'"'"'s tissues; and occluding the HAS. - View Dependent Claims (40, 41, 42, 43, 44, 45, 46, 47, 48, 49)
