    摘要: A screw-in electrode probe for cardiological application comprises an oblong electrode body (1), a supply line (10) running therein, and an electrode head (3) on the distal end (2). The latter is provided with housing (5), a shaft (6) mounted therein so it is rotatable and axially displaceable, and a corkscrew-like screw-in electrode (4) on the shaft (6). A contact spring in the form of an essentially planar spiral spring (11) is situated between these components, whose leg ends (12, 13) are in sliding contact with the housing (5) or the shaft (6), respectively, while exerting a radially directed spring force (F).
