  • Publication number: 20190104994
    Abstract: Systems and methods are presented for localization of a capsule based on magnetic fields. The capsule is positioned in a magnetic field generated by a first magnet and an electromagnetic coil is operated to generate a sinusoidal magnetic field with a magnetic moment orthogonal to the magnetic moment of the first magnet. An average signal measurement calculated for each magnetic field sensor is defined as the magnetic field applied to the magnetic field sensor by the first magnet and used as an offset to determine the magnetic field applied by the electromagnetic coil. The pose of the capsule is then determined based at least in part on a combination of magnetic field signals applied by the electromagnetic coil to each of the magnetic field sensors.

  • Patent number: 9579163
    Abstract: Robotic platform for mini-invasive surgery comprising robotic arms (4a, 4b) suitable to be placed in the body of a patient, introduced through a single access port, which are an extension of external robotic manipulators (19). The continuity between external (1) and internal (4a, 4b) robotic arms is guaranteed by means of a trans-abdominal magnetic connection (6) between the internal robotic arm integral with the external one. The trans-abdominal magnetic coupling not only guarantees a stable anchoring, but most of all it transfers degrees of freedom to the internal robotic arms, inducing the motion of internal magnets by means of the automatized motion of external magnets. It is also possible to reposition the internal robotic arms without requiring having to additionally perform incisions on the abdomen. Using the external robotic arms allows translating the internal ones on the entire abdomen thus providing a working space not bound to the point of insertion and theoretically unlimited.

  • Publication number: 20150342501
    Abstract: Systems and methods are described for determining an orientation and position of a capsule inserted into the body of a patient. A magnetic field is applied to an area of the patient where the capsule is located. Sensor data, including inertial data from an inertial sensor and magnetic field data indicative of the applied magnetic field as detected by at least one magnetic field sensor, is wirelessly received from the capsule. An orientation angle of the capsule is determined based at least in part on the inertial data. The magnetic field data is compared to known characteristics of the applied magnetic field and a location of the capsule is determined based on the comparison.

  • Publication number: 20140081120
    Abstract: A system and method of detecting and assessing a tissue surface property without a separate access port to internal anatomical structures. The system includes a first unit positioned outside the patient's body and a second unit positioned inside the patient's body. The first unit includes a magnetic field source and a force sensor and is positioned outside the patient's body in a position that enables magnetic coupling with the second unit, which is inside the patient's body. The second unit includes a magnetic field source, a processor, a sensor, a telemetry unit, a power source, and an optional actuator or other components. The resulting attractive force between the internal and external magnetic field sources can be perceived by the force sensor of the first unit. By varying the distance between the two units, the attractive force triggers a variable stress on the tissue surrounding the second unit in the direction of the magnetic field source in the first unit.
