First Claim
Patent Images
1. Apparatus for treating a hollow anatomical structure of a patient, said apparatus comprising:
- a bioabsorbable occlusive implant sized for insertion into said hollow anatomical structure, said implant having a proximal end and a distal end spaced longitudinally from said proximal end, said implant having an implant body extending from said proximal end to said distal end, said implant body having an outer side portion configured to engage an inner wall of said hollow anatomical structure; and
a stabilization member extending proximally of said proximal end of said implant, said stabilization member having a stabilization portion spaced proximally from said proximal end of said implant, said stabilization portion being configured for attachment to the anatomy of said patient to inhibit distal movement of said implant in said hollow anatomical structure.

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.

19. A method of treating a hollow anatomical structure of a patient, said method comprising:
-
implanting a bioabsorbable occluder into said hollow anatomical structure;
fixing said occluder in said hollow anatomical structure to inhibit post-operative movement of said occluder within said hollow anatomical structure; and
with said occluder, causing fibrosis and blockage of said hollow anatomical structure. - View Dependent Claims (20, 21, 22, 23, 24, 25)
