Patent ID: 7766932

Claim:
A vessel filter for filtering solids in a liquid flowing through said vessel filter, said vessel filter designed for use with a magnetic resonance tomograph having an external magnetic field, said magnetic field having a tomograph frequency, said vessel filter comprising: a conductor having a first end and a second end, the entire length of said conductor bent into a shape that provides mechanical filtering and also creates an inductance, wherein said first end and said second end are proximate one another; a nonconductive dielectric positioned between said first end and said second end in order to prevent shorting between said first end and said second end, wherein a capacitance is thereby created by said first end, said nonconductive dielectric, and said second end, wherein said capacitance and said inductance form a series resonant circuit; wherein said capacitance and said inductance are chosen to have a resonant frequency tuned to said tomograph frequency; wherein the conductor forms solely the vessel filter and said filtering is solely performed by said conductor and nonconductive dielectric; wherein said ends of said conductor are insulated with an insulator that represents said dielectric and forms said capacitance with said ends separated by said insulator; and wherein said vessel filter is configured to be implanted within a vessel.
