Electrode arrangement and measuring device for measuring the electrical activity in an electrically active tissue
First Claim
1. An electrode for measuring electrical activity of tissue, the electrode comprising:
- a sensing electrode having an elongate electrode body forming a partial hollow half cylindrical section having a proximal end, a distal end, and a curved inner surface configured to partially enclose a curved outer surface of the tissue and with;
i. a penetrating end at the distal end for insertion into the tissue to sense electrical activity of the tissue, andii. a base end at the proximal end that is coupled to an electrical connection wire for communicating the sensed electrical activity away from the sensing electrode; and
a fixation element that penetrates through an electrode opening in the elongate electrode body into the tissue partially enclosed by the curved inner surface of the partial hollow half cylindrical section of the electrode body to hold the penetrating end of the sensing electrode in position in the tissue.

Abstract
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 (2) and a fixing element (3), the first electrode (2) being connected to a first, long electrical line (4) and consisting of a long base body (6) comprising a first end (7) and a second end (8). The first electrical line (4) is connected to the base body (6) in the region of the second end (8) thereof, and means are provided for reversibly fixing the fixing element (3) to the first electrode (2).
