摘要:
An intravascular filter (10) has a main filter portion (12) and an anchor portion (14). The main filter portion is made up of a number of struts (16), which form a first and a second biodegradable filter sections (26,28). The first and the second biodegradable filter sections biodegrade at different rates. The anchor portion secures the filter within a blood vessel and also has a collar (32). The first and the second biodegradable portions may have a different thickness and may be comprised of different materials. The collar may be formed from a resiliently deformable material.
