Abstract
Abstract An electrode device intended to be temporarily introduced into the body of a living being and to essentially locally treat or electrically measure biological body tissue therein in order to, after performed treatment or measurement, be removed. Said electrode device includes an electrode part (1), provided with an opening to its centre and insertable into the body tissue to be treated or measured, and a supply part (2), which electrically seen is isolated from the remaining body parts, for supply of electricity to said electrode part (1), which supply part (2) is made pliable and contains at least one channel. Said electrode part (1) has an unlimited number of openings to its centre, which openings preferably are evenly distributed along the entire electrode part (1).

Electrode device intended to be temporarily introduced into the body of a living being and to essentially locally treat or electrically measure biological body tissue therein in order to, after performed treatment or measurement, be removed, which electrode device includes an electrode part (1), provided with an opening to its centre and insertable into the body tissue to be treated or measured, and a supply part (2), which electrically seen is isolated from the remaining body parts, for supply of electricity to said electrode part (1), which supply part (2) is made pliable and contains at least one channel, characterized in that said electrode part (1) has an unlimited number of openings to its centre, which openings preferably are evenly distributed along the entire electrode part (1).
Claim 3
Dependent Claim
30 words
Electrode device according to Claim 1, characterized in that the electrode part (1) is variable in size in relation to and inside the body tissue to be treated or measured.
Claim 4
Dependent Claim
40 words
Electrode device according to Claim 2, characterized in that the one, distal end (3) of the electrode part (1) is releaseably fixed at the electrode device and in that the second end (4) of the electrode part (1) is movable.
Claim 5
Dependent Claim
20 words
Electrode device according to Claim 3, characterized in that the electrode part (1) is changeable by adjusting the length thereof.
Claim 6
Dependent Claim
21 words
Electrode device according to anyone of previous Claims, characterized in that the electrode part is made as a spirally wound wire.
Claim 7
Dependent Claim
75 words
Electrode device according to anyone of previous Claims, characterized in that the electrode part (1) is made as a bifilar wound, screw-shaped cable, the one, distal end (3) of which cable comprises two wire ends (3a, 3b), which are clamped to the electrode device, and the other end of which cable is running through said channel of the isolated supply part (2) and out to the surroundings and is preferably arranged as a grip (4).
Claim 8
Dependent Claim
56 words
Electrode device according to anyone of the previous Claims, characterized in that said channel in size is so adapted that it allows for the introduction of an extra channel, which extra channel has such a length that said extra channel can be brought to emerge in the position desired in the centre of the electrode part.
Claim 9
Dependent Claim
33 words
Electrode device according to anyone of the previous Claims, characterized in that the electrode part is made from a thin wire or thread in order to be pliably straightened out during removal thereof.
