Abstract
An apparatus and method are disclosed by which a laser beam is used to remove or ablate the insulating coating from a desired segment of an insulated conductor without damaging or causing mechanical stress to the wire, so that the wire can be used to transmit electrical signals to an electrode in a implantable medical device. The invention can be applied to one or more conductors that are coiled coaxially and can be used to expose separate portions of two or more conductors if the insulating coatings thereon are differentiated in a way that causes the separate insulating coatings to respond differently to contact with a laser beam.
