Abstract
A temporary absorbable venous occlusive stent for use in a varicose vein treatment method includes a stent body, a bio-absorbable material associated with the body, and a closure for blocking blood flow past the stent when implanted in a vein. The stent produces localized blood clotting, fibrosis and vein collapse as it is absorbed. A permanent blockage is produced that prevents the undesirable back flow of blood from above the blockage site, thereby reducing distension of a varicose vein below the blockage site.

21. A method of treating a hollow anatomical structure, said method comprising:
-
inserting into said hollow anatomical structure an implant formed from a bioabsorbable material;
providing a fluid flow path through said implant; and
causing blockage of said flow path after said inserting. - View Dependent Claims (22, 23, 24, 25, 26, 27)

28. A method of treating a hollow anatomical structure of a patient, said method comprising:
-
implanting a bioabsorbable occluder into said hollow anatomical structure;
with said bioabsorbable occluder, causing a partial occlusion of said hollow anatomical structure; and
with said bioabsorbable occluder, causing a subsequent, substantially complete occlusion of said hollow anatomical structure. - View Dependent Claims (29, 30, 31, 32, 33, 34, 35, 36, 37, 38)

39. A method of reducing flow through a blood vessel, said method comprising:
-
inserting into said blood vessel an occluder comprising a bioabsorbable material;
fixing said occluder in said hollow anatomical structure to inhibit post-implantation movement of said bioabsorbable occluder within said hollow anatomical structure;
with said occluder, causing a partial occlusion of said blood vessel; and
with said occluder, causing a subsequent, substantially complete occlusion of said blood vessel. - View Dependent Claims (40, 41, 42)

43. Apparatus comprising:
-
an implant formed from a bioabsorbable material, said implant having a distal end and a proximal end opposite said distal end;
said implant having a first state in which a fluid flow path passes through said implant between said distal end and said proximal end, and a second state in which substantially no fluid flow path passes through said implant. - View Dependent Claims (44, 45, 46, 47)
