Abstract:
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: 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.
