Apparatus for coagulating tissue
First Claim
1. Apparatus for coagulating tissue, comprising an HF generator, an electrode connected to said HF generator and adapted to produce a high-frequency current, a gas-delivering device defining an outlet and adapted to deliver, in use, an inert gas from said outlet of said gas-delivering device into a space defined between said electrode and said tissue such that between said electrode and said tissue a plasma is produced, a distal end of said electrode projecting out of said gas-delivering device, and a guiding device for directing and guiding at least one of said gas and said plasma disposed at said distal end of said electrode and adapted such that at least a part of said at least one flowing gas and plasma is diverted into a predetermined direction.

Abstract
For the coagulation of tissue there are known instruments, in particular probes, that are designed to deliver argon gas into a space between an electrode within the probe and the tissue. In some cases the intention is to coagulate tissues situated at the side of the outlet of the probe. The invention provides an apparatus for coagulating tissue in which the distal end of the electrode projects out of the gas-delivering device or probe, and at said distal end a guiding device for directing and guiding the gas or plasma is disposed in such a way that at least part of the flowing gas or plasma is deflected into a predetermined direction.
