US 8105325 B2Abstract
24. The method of claim 23, wherein the electric arc is capable of heating the generated plasma in the high pressure chamber to a temperature between 11,000 and 20,000°C.
According to a fourth aspect of the invention, a method of generating a plasma by a plasma-generating device is provided, comprising an anode, a cathode and a plasma channel which extends substantially in the direction from said cathode to said anode, said method comprising providing a plasma flowing from the cathode to the anode; (this direction of the plasma flow gives meaning to the terms “upstream” and “downstream” as used herein); increasing energy density of said plasma by pressurizing the plasma in a high pressure chamber which is positioned upstream of a throttling portion arranged in the plasma channel; heating said plasma by using at least one intermediate electrode which is arranged upstream of the throttling portion; and decompressing and accelerating said plasma by passing it through said throttling portion and discharging said plasma through an outlet opening of the plasma channel.
FIG. 1 a is a cross-sectional view of an embodiment of a plasma-generating device 1 according to the invention. The cross-section in FIG. 1 a is taken through the centre of the plasma-generating device 1 in its longitudinal direction. The device comprises an elongate end sleeve 3 which accommodates a plasma-generating system for generating plasma which is discharged at the end of the end sleeve 3. The discharge end of sleeve 3 is also referred to as the distal end of device 1. In general, the term “distal” refers to facing the discharge end of the device; the term “proximal” refers to facing the opposite direction. The terms “distal” and “proximal” can be used to describe the ends of device 1 and its elements. The generated plasma can be used, for instance, to stop bleeding in tissues, vaporize tissues, cut tissues etc.
