Abstract
A device for mobilizing, rotating and maneuvering an in vivo vehicle introduced into a subject by extracorporeal devices which control the position and motion of such a vehicle by detection and modulation of the strength and direction of the electromagnetic field vector of the vehicle. This invention employs a series of pulses, with specific characteristics over time, to induce magnetic field changes. The changes that result from the vehicle movement are measured and used to calculate the location and movement of the vehicle. A system and method for controlling the movement of the vehicle are also provided.
Claims73
A system for managing an in vivo vehicle in a subject, comprising:
- a. a magnet being physically associated with the vehicle;
- b. an extracorporeal magnetic source for producing a magnetic field for being applied to said magnet, said extracorporeal magnetic source being located outside of the subject;
- c. a detector for detecting a magnetic field from said magnet, said detector being located outside of the subject;
- and
- d. a control module for receiving a magnetic field measurement from said detector and for managing the vehicle according to said magnetic field measurement.
The system of 19, wherein the vehicle's path inside the body is controlled at least partially according to information received directly from the vehicle.
A system for managing an in vivo vehicle in a subject, wherein managing includes at least determining a location of the vehicle in the subject, the system comprising:
- a. a magnet being physically associated with the vehicle;
- b. an extracorporeal magnetic source for producing a magnetic field for being applied to said magnet, said extracorporeal magnetic source being located outside of the subject;
- and
- c. a detector for detecting a magnetic field from said magnet, said detector being located outside of the subject, such that a location of the vehicle is determined according to said magnetic field measurement.
