Claim 0:
1. 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.
