DEVICE FOR APPLYING ENERGY TO A TARGET

摘要

A probe for applying energy to a target, and a method for its use. The probe includes a sensor [28] for determining the position of the probe, and a generator of a force field that interacts with the target to apply the energy to the target. To minimize interactions between the sensor and the force field generator, the force filed generator is disposed relative to the sensor [28] so that there is a node of the force field at the sensor. For example, if the sensor [28] is at an element of symmetry of the catheter, the force field generator is disposed so that a node of the force field is coincident with that element of symmetry. The sensor is used to ensure that the probe remains in proximity to the target while the energy is applied to the target.
