Abstract:
A removable blood clot filter includes a number of locator members and anchor members, and a bio-resorbable structure that causes locator members and/or anchor members to deploy to an initial configuration which changes when the bio-resorbable structure is resorbed. The bio-resorbable structure causes the filter locator members and/or anchor members to press against the vessel wall sufficient to locate and anchor the filter upo delivery. After the bio-resorbable structure is resorbed, the locator members and/or anchor members change shape to apply less pressure against the vessel wall. The bio-resorbable structure may be activated by exposure to radiation so that actuation of the locator members and/or anchor members can be enabled or initiated by a clinician.
