Abstract
Disclosed embodiments provide an apparatus and method for brushing plaques from vessels by exposing intraluminal nanoparticles to changing magnetic gradients.
Claims24
A system for reducing plaque in a vessel, the system comprising:
- at least one nanoparticle introduced into a vessel;
- at least one magnet positioned in proximate relationship to the vessel and manipulated to induce motion of the at least one nanoparticles in the vessel as a result of exposure to changing magnetic gradients resulting from manipulation of the at least one magnet,
- wherein the induced motion of the at least one nanoparticle causes a reduction in volume of plaque located in and/or located on walls the vessel.
A device comprising:
- a plurality of small magnetizable particles,
- wherein introduction of the plurality of particles into one or more vessels along with subsequent manipulation of a magnetic field applied to the one or more vessels results in motion of the plurality of particles that causes a reduction in volume of plaque located in and/or located on walls of the one or more vessels.
A method of reducing plaque in a vessel, the method comprising:
- introducing at least one nanoparticle into a vessel;
- and
- manipulating a magnetic field produced by at least one magnet positioned in proximate relationship to the vessel to induce motion of the at least one nanoparticle in the vessel as a result of exposure to changing magnetic gradients resulting from the manipulation of the at least one magnet,
- wherein the induced motion of the at least one nanoparticle causes a reduction in volume of plaque located in and/or located on walls the vessel.
