An electrode arrangement for sensing electrical activity in target tissue is described. A support electrode has an elongate electrode body with a base end and a penetrating end for insertion into the target tissue. A fixation electrode has an elongate electrode body with a base end and a penetrating end at an angle to the electrode body. The electrodes are joined together with their electrode bodies in parallel so that the penetrating end of the fixation electrode penetrates a fixed distance into the target tissue so that at least one of the electrodes senses electrical activity in the target tissue.

Electrode configuration and measuring device for measuring the electrical activity in electrically active tissue

The invention relates to an electrode arrangement and a measuring device for measuring the action flow and/or the action potential of an electrically active tissue. The aim of the invention is to provide a simple and economically producible electrode for measuring action flows and/or action potentials in electrically active tissues (preferably the stapedius muscle tissue), ensuring that the electrode is fixed securely, but reversibly, in the muscle tissue and that the muscle tissue is disturbed as little as possible. The electrode arrangement according to the invention comprises a first electrode () and a fixing element (), the first electrode () being connected to a first, long electrical line () and consisting of a long base body () comprising a first end () and a second end (). The first electrical line () is connected to the base body () in the region of the second end () thereof, and means are provided for reversibly fixing the fixing element () to the first electrode ().

Electrode arrangement and measuring device for measuring the electrical activity in an electrically active tissue

An electrode arrangement is described for sensing electrical activity in target tissue. An inner electrode has an elongate electrode body formed as a cylindrical section with an inner penetrating end for insertion into the stapedius muscle target tissue. An outer electrode fits over the inner electrode and an outer penetrating end for insertion into the target tissue. The two electrodes are joined together with their electrode bodies in parallel so that the penetrating ends of the electrodes penetrate in the same direction into the target tissue to sense electrical activity in the target tissue.

Evoked stapedius reflex threshold (ESRT) tile electrode

The invention relates to a stapedius muscle electrode array for detecting the action elements generated when a human stapedius muscle is contracted. Said array comprises an electrode (&#x2033;) that is adapted for bipolar discharge and is to be attached to a human stapedius muscle. The electrode has two flexible, elastic, electrically conducting elongate elements (), each of which has a distal () and a proximal end () and is helically preshaped along at least some of the length thereof to the distal end () thereof in such a way that the distal end () and a section of the respective elongate element () which adjoins the distal end () can be placed at least in part around the tendon () extending between the stapedius muscle and the stapes while the helical part can be guided along the tendon (), can be moved in the direction of the stapedius muscle, and can be at least partly twisted into and/or slid onto the region of the muscle belly () adjoining the tendon (). The two elongate elements () are electrically insulated from one another, and the helical parts () thereof are intertwined in such a way as to run around a common centerline (), allowing the helical parts () to be jointly placed around the tendon (), be guided along the tendon (), and be brought in contact with the stapedius muscle.
