Abstract: The invention relates to a device for in vivo positioning and fixing of electrodes on body organs, and the manufacture thereof. The invention provides a device for in vivo position, repositioning and fixing of electrodes on body organs, in particular the human heart, comprising: at least one electrode adapted to exchange electrical signals with a body organ, communication means connected to the electrode for co-action with measuring and control means, and at least one resilient fixation element connected to the electrode, wherein the fixation element is expandable from a relatively compact form to a relatively voluminous form, and wherein the fixation element is adapted to press the electrode under bias against the body organ in the relatively voluminous form in co-action with surrounding body tissue in order to maintain the desired position.

Abstract: The invention relates to an electrical connector for conveying an electrical signal from a device, in particular a cardiac device, to an organ of a human or animal body, in particular a heart, comprising a first electrically conducting wire and a second electrically conducting wire, wherein the wires are joined together in an electrically insulating sleeve, a first electrode, which is electrically connected to the first wire, and a second electrode, which is electrically connected to the second wire; wherein the first and second electrodes are constructed to deliver an electrical signal at the organ, wherein the first electrode forms an electrically conducting sleeve around a conducting part of the first wire and around a non-conducting part of the second wire, wherein at least the edges of the electrically conducting sleeve formed by the first electrode are at least partially embedded in the electrically insulating sleeve.
