Gewebeschonendes Instrument zur Stimulation und/oder Ableitung von bioelektrischen Signalen

(A1) Die vorliegende Erfindung betrifft ein Instrument zur Stimulation und/oder Ableitung bioelektrischer Signale in biologischem Gewebe. Das Instrument umfasst einen lang gestreckten zentralen Koerper mit einer Spitze und seitlich angebrachten flexiblen Elementen, die freigelegte Elektrodenkontakte tragen. Die flexiblen Elemente lassen sich unter Aufbau einer Vorspannung an den zentralen Koerper anlegen und stehen in einem entspannten Zustand vom zentralen Koerper ab. Das vorgeschlagene Instrument ermoeglicht eine gewebeschonende Implantation von Elektroden in das Gewebe.

DE 102007020377 A1 UPAB: 20081126 NOVELTY - The instrument has a long stretched central body with a cone point and flexible elements with opened electrode contacts (5), which are laterally connected with the body. The electrode contacts are electrically contactable over connection lines (6) in the elements and the body at the cone point relative to lying end of the body. The elements are formed in such a manner that in a relaxed condition elements are laterally away from the central body, and apply itself to the central body between the configuration of an internal voltage. USE - Instrument for stimulation and conduction of bioelectric signals in biological texture. ADVANTAGE - The electrode contacts are electrically contactable over connection lines in the elements and the body at the cone point relative to lying end of the body, and elements are formed in such a manner that in a relaxed condition elements are laterally away from the central body, and apply itself to the central body between the configuration of an internal voltage, and hence ensures an instrument with a smaller measure of texture destruction within the area of the electrode contacts in the texture implant.
