Controllable Magnetic Source to Fixture Intracorporeal Apparatus
A first magnetic field can be produced across a tissue region using a first magnetic field source, providing a magnetic coupling force between the first magnetic field source and a first object, wherein the first object provides a magnetic field or a magnetic susceptibility to obtain the magnetic coupling force. The magnetic coupling force can be sensed using a force sensor and a resulting sensed force signal can be provided to a controller. The controller can provide an output signal to control the magnetic coupling force using the sensed forced signal to obtain a constant or desired magnetic coupling force.
