Abstract:
1. A plasma surgical apparatus for incising a target tissue comprising: a radiofrequency signal generator; an elongated flexible catheter configured to be inserted in to a blood vessel having a proximal end and a distal end, the proximal end being coupled to a conditioning network and the distal end having a distal end incising electrode tip; a conditioning network coupled to the output of the radiofrequency signal generator, wherein the conditioning network varies at least one of impedance, frequency, power, or q-curve output to tune radiofrequency energy produced by the radiofrequency signal generator such that the energy is absorbed by the molecular lattice of the target tissue in contact with the distal end incising electrode tip, the molecular bonds of the lattice to fracture, and the fractured molecular particles are transformed into a harmonious plasma cloud, the harmonious plasma cloud coating the distal end incising electrode tip, contributing to the increased concentration of energy in the intended path of incision to achieve a cleaner, more precise, more powerful, and more efficient incision with less energy spillover on non-target tissue outside an intended incision path; wherein a plasma fuel is not necessary.
