Abstract
A magnetic marker for marking a site in tissue in the body. In one embodiment, the marker comprises a magnetic metallic glass. In another embodiment, the marker is in a non-spherical configuration having an anisotropy ratio less than 9. In yet another embodiment, the marker is in a non-spherical configuration having an anisotropy ratio less than 6. In yet another embodiment, the marker is in a non-spherical configuration having an anisotropy ratio less than 3.
Claims19
A packed magnetic marker held within a delivery device for marking a site in tissue in the body comprising a non-spherical configuration prior to deployment having a ratio of maximum magnetic response to minimum magnetic response (ratio of magnetic anisotropy of susceptibility) after deployment of less than 5.
A magnetic marker for marking a site in tissue in the body comprising:
- a plurality of magnetic components linked by flexible non-magnetic components that reconfigures upon placement in the site.
A magnetic marker for marking a site in tissue in the body comprising:
- a magnetic component made of one or more materials of a first shape located within a non-magnetic matrix of a second shape.
A magnetic marker for marking a site in tissue in the body comprising:
- a magnetic material core within a magnetic material sheath.
A magnetic marker for marking a site in tissue in the body comprising:
- a plurality of magnetic components which self assemble into the magnetic marker following placement of the markers into the body.
A magnetic marker for marking a site in tissue in the body comprising a magnetic metallic glass.
