Abstract
A method, system, and device for magnetically pushing agents into an eye. The agents are magnetic or magnetizable or magnetically responsive.
Claims10
A method for treating an eye disease in a subject by pushing a therapeutic agent to a target location of a treatment site, the method comprising:
- (a) providing, by a delivery device, a plurality of push nodes each generated by overlapping combined magnetic fields of a plurality of magnetic elements, wherein each of the plurality of push nodes are local magnetic field strength minimums configured to emit magnetic forces, and wherein the magnetic elements are permanent magnets;
- (b) placing, the therapeutic agent locally on an eye of the subject;
- (c) aligning, the delivery device, to configure the plurality of push nodes to emit magnetic forces directionally towards the target location;
- and
- (d) pushing, by the plurality of push nodes, the therapeutic agent, wherein a predetermined amount of the therapeutic agent is pushed into the eye by the magnetic fields to the target location of the treatment site;
- wherein at least two magnetic elements of the plurality of magnetic elements of the delivery device are pivotably arranged at an angle with respect to each other via a pivot mechanism in the delivery device;
- and
- wherein the therapeutic agent permeates into the eye, and the magnetic forces emanating from a first push node of the plurality of push nodes and a second push node of the plurality of push nodes push the therapeutic agent to a first target location and a second target location within the interior of the eye.

A method to decrease eye trauma in a subject while treating an eye disease in an eye of the subject, the method comprising:
- (a) generating, by a delivery device, a magnetic field using a plurality of magnetic elements, wherein:
- the plurality of magnetic elements are permanent magnets, and wherein the plurality of magnetic elements includes a first set of magnetic elements having a first magnetization and a second magnetization, and produces a first magnetic field and a second magnetic field, the first magnetic field and the second magnetic field overlap to create a first combined field and a first push node that is configured to emit a first set of magnetic forces;
- and
- the plurality of magnetic elements includes a second set of magnetic elements having a third magnetization and a fourth magnetization, and produces a third magnetic field and a fourth magnetic field, the third magnetic field and the fourth magnetic field overlap to create a second combined field and a second push node that is configured to emit a second set of magnetic forces;
- (b) placing, a therapeutic agent locally on the eye of the subject;
- (c) placing, the delivery device, proximal to the subject;
- (d) pushing, by the first and second push nodes, the therapeutic agent using the first set and second set of magnetic forces, wherein the exterior of the eye is materially intact during a treatment;
- and
- (e) adjusting, the plurality of magnetic elements with respect to each other via a pivot mechanism in the delivery device to configure the first set of magnetic forces to aligned directionally towards a first target location and the second set of magnetic forces to aligned directionally towards a second target location;
- wherein at least two magnetic elements of the plurality of magnetic elements of the delivery device are pivotably arranged at an angle with respect to each other;
- and
- wherein the therapeutic agent permeates into the eye, and the magnetic forces emanating from the first push node and the second push node push the therapeutic agent to the first target location and the second target location within the interior of the eye.
