Controlled release mechanism for blood vessel filtration device

A filtration system comprising:

• a. a filtration device comprising;
• i. a body configured for placement within a portion of the vasculature of a patient, wherein the body comprises a plurality of threads, each thread having a proximal end and a distal end;
• ii an cap forming an apex, wherein at least one of the cap and the body comprises a selectively transformative material;
• iii. a first configuration, wherein the cap substantially retains the distal end for each of the plurality of threads at the apex such that the filtration device is substantially operable;
• and
• iv. a second configuration, wherein 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;
• and
• b. an electromagnetic induction system, the electromagnetic induction system being configured to generate a magnetic field sufficient to selectively transform the filtration device from the first configuration to the second configuration.

A filtration method comprising the steps of:

• providing a filtration device comprising;
• a. a body configured for placement within a portion of the vasculature of a patient, wherein the body comprises a plurality of threads, each thread having a proximal end and a distal end;
• b. an cap forming an apex, wherein at least one of the cap and the body comprises a selectively transformative material;
• c. a first configuration, wherein the cap substantially retains the distal end for each of the plurality of threads at the apex such that the filtration device is substantially operable;
• and
• d. a second configuration, wherein 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;
• providing an electromagnetic induction system;
• inserting the filtration device into a portion of the vasculature of a patient;
• and
• generating a magnetic field with the electromagnetic induction system to selectively transform the filtration device from the first configuration to the second configuration.
