Abstract
Some embodiments provide a system for external manipulation of magnetic nanoparticles in vasculature using a remotely placed magnetic field-generating stator. In one aspect, the systems and methods relate to the control of magnetic nanoparticles in a fluid medium using permanent magnet-based or electromagnetic field-generating stator sources. Such a system can be useful for increasing the diffusion of therapeutic agents in a fluid medium, such as a human circulatory system, which can result in substantial clearance of fluid obstructions, such as vascular occlusions, in a circulatory system resulting in increased blood flow.
Claims16
A system comprising:
- at least one motor,
- a magnet,
- a controller,
- a reservoir, and
- an agitating mechanism;
- wherein the controller is configured to cause the at least one motor to control a position and a movement of a magnetic field of the magnet;
- wherein the controller is configured to cause magnetic nanoparticles to generate a fluidic current within a blood vessel proximal to a fluid obstruction;
- and
- wherein the agitating mechanism is configured to maintain a dispersion of the magnetic nanoparticles within the reservoir.
A system comprising:
- at least one motor,
- a magnet,
- a controller,
- a drip bag, and
- a mechanical agitator;
- wherein the controller is configured to cause the at least one motor to control a position and a movement of a magnetic field of the magnet;
- wherein the controller is configured to cause magnetic nanoparticles to generate a fluidic current within a blood vessel proximal to a fluid obstruction;
- and
- wherein the mechanical agitator is configured to maintain a dispersion of the magnetic nanoparticles within the drip bag.
A system comprising:
- at least one motor;
- a magnet,
- a controller,
- an infusion pump,
- multiple syringes,
- an outlet tubing, and
- a manifold;
- wherein the controller is configured to cause the at least one motor to control a position and a movement of a magnetic field of the magnet;
- and
- wherein the controller is configured to cause magnetic nanoparticles to generate a fluidic current within a blood vessel proximal to a fluid obstruction.
