<p>An improved pacemaker lead including a lead body supporting at least one flexible conductor element that provides an electrical signal path between a proximal connector element and a distal electrode. The lead body includes an insulating structure that protects the flexible conductor element(s) wherein the insulating structure is realized from a polymer material comprises an isobutylene block copolymer. The polymer material of the insulating structure has a maximum tensile strength in the range between 20 MPa and 40 MPa (most preferably in a range between 25 MPa and 35 MPa) In the preferred embodiment, the hardness of the polymer material of the insulating structure can be characterized by a Shore hardness in a range between 70A and 80A.</p> |
