System for targeted medical intervention using a magnetic field

A system for steering self-propelled magnetotactic entities in a body of a subject, the system comprising:

• a first vertical support oriented in a transverse direction (y-axis) and having an upper portion in communication with a first lower portion (+y) and a second lower portion (−y);
• a second vertical support spaced from the first lower portion (+y) of the first vertical support in a longitudinal direction (+x);
• a third vertical support spaced from the second lower portion (−y) of the first vertical support in the longitudinal direction (+x) and spaced from the second vertical support in the transverse direction (y-axis);
• and
• a first pair of opposing magnetic heads arranged along a first axis, a first magnetic head of the first pair of opposing magnetic heads being affixed to the upper portion of the first vertical support and a second magnetic head of the first pair of opposing magnetic heads being affixed to a floor, the first axis forming an acute angle with respect to a plane of the floor;
• a second pair of opposing magnetic heads arranged along a second axis substantially orthogonal to the first axis, a first magnetic head of the second pair of opposing magnetic heads being affixed to the second lower portion (−y) of the first vertical support and a second magnetic head of the second pair of opposing magnetic heads being affixed to an upper portion of the second vertical support (+y);
• and
• a third pair of opposing magnetic heads arranged along a third axis substantially orthogonal to the first axis and the second axis, a first magnetic head of the third pair of opposing magnetic heads being affixed to the first lower portion (+y) of the first vertical support and a second magnetic head of the third pair of opposing magnetic heads being affixed to an upper portion of the third vertical support.
