Abstract
A device for manipulating a magnetic coupling force across tissue in response to a monitored coupling force is described. The device includes a magnetic field source assembly, a positioning assembly operatively connected to the magnetic field force assembly, and a magnetic coupling force monitor. The magnetic field source assembly includes magnets that provide an external magnetic field source for providing a magnetic field across tissue. The positioning assembly adjusts the position of the magnetic field source. The magnetic field creates a magnetic coupling force between the external magnetic field source and an object positioned in use in a patient during a procedure, wherein the object has or is associated with an internal magnetic field.
Claims19
A device for manipulating a magnetic coupling force across tissue comprising:
- a magnetic field source assembly comprising a first magnetic field source for providing, in use, a magnetic field across tissue, the first magnetic field providing a magnetic coupling force between the first magnetic field source and an object providing a second magnetic field source;
- a positioning assembly operatively connected to the magnetic field force assembly for adjusting the elevational position of the first magnetic field source, the positioning assembly having a driver for adjusting the elevational position of the magnetic field force assembly and an actuator for moving the driver;
- and
- a magnetic coupling force monitor.
