CONTROLLED RELEASE MECHANISM FOR BLOOD VESSEL FILTRATION DEVICE
First Claim
1. 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 filter 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.

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.

10. 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. - View Dependent Claims (11, 12, 13, 14)

15. 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. - View Dependent Claims (16, 17, 18, 19, 20)
