Publication number: 20130156933Abstract: The present invention relates to methods for manufacturing active fixation helices for the stimulation and/or sensing of organs. A first embodiment of a method in accordance with the present invention for making a helix comprises a first step of producing an elongated helix precursor body comprising 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.Type: ApplicationFiled: July 13, 2012Publication date: June 20, 2013Applicant: ST.
