摘要：
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 patients body and a second unit positioned inside the patients body. The first unit includes a magnetic field source and a force sensor and is positioned outside the patients body in a position that enables magnetic coupling with the second unit, which is inside the patients 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.
