In a method for manufacturing active fixation helices for the stimulation and/or sensing of organs, an elongated helix precursor body is produced that has one or more electrical conductors surrounded by an insulating material. This helix precursor body is then shaped into a helix, material removed in predetermined places in order to expose the areas of the conductors which will be used as electrodes in the final product. The body is coated with an electrically conducting biocompatible coating which is subsequently partly removed in continuous loops from around the electrodes in order to electrically insulate them from each other and to ensure that the electrically active areas of the electrodes are of the correct dimensions.

Method for manufacturing an active fixation electrode

A medical implantable lead has a proximal end and a distal end, and a flexible flat elongate body. The elongate body includes a layer of strip conductors extending along the length of the flat elongate body, a top insulating layer, and a bottom insulating layer. The layer of strip conductors is sealingly enclosed between the top and bottom insulating layers, and at least a major portion of the flat elongate body is twisted into an elongate helical portion having a central cavity extending longitudinally of the helical portion.

Medical implantable lead

A sealing plug having a self-sealing access slit is provided in a medical implant. An insert is inserted into the self-sealing access slit to preserve the slit during storage.
