Abstract: A filtration device is disclosed having a body configured for placement within a portion of the vasculature of a patient, where the body includes a plurality of threads, each thread having a proximal end and a distal end. The filtration device further includes an cap forming an apex, wherein at least one of the cap and the body include a selectively transformative material. The filtration device has a first configuration, where the cap substantially retains the distal end for each of the plurality of threads at the apex such that the filter device is substantially operable and a second configuration, where the filtration device is substantially inoperable as a result of at least one of the body and the cap being selectively transformed by electromagnetic induction. Systems and methods involving such filtration devices are also disclosed herein.
