Radiofrequency bipolar fields
As the most modern devices for pulsed radiofrequency treatments, Pulstrode generates a bipolar electric field stimulating the nervous tissues in the target area ONLY. The ability of being able to perform bipolar treatments ensures a better treatment performance since the energy delivered is focused only in areas to treat and it is not lost in ground plates, as is the case of monopolar systems..
One of the most important features of Pulstrode is the ability to modify the length of the applied electric field. In the lead tip are present not two, but rather THREE active electrodes: through a switch located at the base of the catheter it is possible to choose between two bipolar fields of different lengths.
The variable bipolar field
This important feature allows the physician ability to modify the field length if conditions are satisfied to further improve treatment effectiveness.
Sometimes they present particular anatomical conditions, such as high impedance due to fibrosis or adhesions of tissues or significant stenosis, for which the operating space is limited. That's in these cases is very useful to be able to modify, without any external maneuver, the length of the bipolar field.
By varying the field length, infact it allows to recruit a greater number of nerve fibers, that often are capable of lowering the impedance of tissues and hence to foster a greater radio frequency current, improving the treatment effectiveness.
Bipolar Radiofrequency fields
With Pulstrode can be carried out radiofrequency with electric fields between the first two electrodes (Small) or extend the range of action generating electric fields between the two outermost electrodes (Large).
(A) Monopolar with groundplate: the electrical circuit is closed on a plate where the dispersed energy is re-channeled in the circuit.
(B) Monopolar with ground needle: the needle performs the same function of the groundplate with the difference that in this case the current is not dispersed.
