Abstract

A medical method is provided, including a medical device having a distal assembly including at least one electrode and at least one treatment element, the medical device generating information regarding at least one of a physiological measurement and an operational parameter of the medical device; a plurality of surface electrodes affixable to a skin of the patient, wherein the surface electrodes are in electrical communication with the distal assembly to obtain position information of the medical device; and a processor pairing the position information and the at least one of a physiological measurement and an operational parameter of the medical device.

Claims (9)

1. A medical system comprising:

a medical device having a distal assembly including at least one electrode and at least one treatment element, the medical device obtaining information regarding impedance;

a plurality of surface electrodes affixable to a skin of a patient, wherein the surface electrodes are in electrical communication with the distal assembly to obtain position information of the medical device;

an energy generator in electrical communication with the distal assembly and the plurality of surface electrodes, the generator being configured to deliver ablation energy to the treatment element in unipolar mode and bipolar mode simultaneously;

a processor, the processor being configured to obtain the information regarding impedance from the medical device and the position information of the medical device from the plurality of surface electrodes simultaneously when ablation energy is being delivered to the treatment element, the processor pairing the position information and the information regarding impedance.

2. The medical system of claim 1 , further comprising a reference electrode affixable to the skin of the patient in electrical communication with the distal assembly.

3. The medical system of claim 2 , wherein the treatment element is a radiofrequency ablation element.

4. The medical system of claim 1 , wherein the plurality of electrodes includes at least three pairs of surface electrodes.

5. The medical system of claim 4 , wherein the at least three pairs of surface electrodes cooperate with the distal assembly to measure electric potential in three different planes.
