Abstract
The invention relates to an implantable blood filter comprising a self-expanding external structure made from a zigzagged thread wound on itself in order to exhibit a closed configuration. A central strainer section is connected to the said thread at various points for the retention of possible blood clots. This strainer section may be made from a biologically absorbable material. Applications include the production of medical blood filters, which are self-centering and absorbable.
