Abstract

1490585 Cauteries; surgical cutting, devices RICHARD WOLF GmbH 20 May 1975 [30 May 1974] 21651/75 Heading A5R A device for removing, dividing or coagulating tissue, comprises two electrical conductors 2, 3 extending through an insulating sheath 4 and connectible proximally to a source of H.F. current, said conductors continuing distally to form electrode members having mutually spaced, insulation-free parts 8, and the distal ends of the electrode members being held together at a distance from one another in an insulating member 7. Sheath 4 may be flexible.
