A medical device for ablating tissues within a heart chamber comprising a guiding member intended to be introduced in the oesophagus of the patient and an ablating member comprising an ablation electrode mounted at the distal end or tip of catheter. Both the head of the guiding member and the tip of the ablating member are magnetised and can enter into magnetic coupling when their distal ends are brought in close contact. Once the magnetic coupling is achieved, the tip of the ablating member is guided by moving the guiding member. The guiding member can include sensors enabling to monitor physiological parameters during the intervention.

Medical device for tissue ablation

The invention concerns an inertial sensor or an actuator based on diamagnetic levitation, said inertial sensor or actuator comprising support means serving as main support body for an inertial sensor or for an actuator, a two dimensional array of permanent magnets and a diamagnetic element facing the said array characterized in that said diamagnetic material constitutes the inertial mass or the moving part of the actuator.
