Abstract:
1. An implantable medical electrical lead comprising: a first conductive modular lead, said first conductive modular lead including a conductive layer insulated by electrically insulating material, said first conductive modular lead including a first interface and a second interface; a capacitor modular component, said capacitor modular component including a self-healing dielectric material disposed between a pair of conductors, said capacitor modular component having a second interface and a first interface configured to match and couple to said first interface of said first conductive modular lead; and a second conductive modular lead, said second conductive modular lead including a conductive layer insulated by electrically insulating material, said second conductive modular lead including a first interface and a second interface; said second interface of said second conductive modular lead being matched with and coupled to said second interface of said capacitor modular component, wherein the self healing dielectric material is configured to have a dielectric voltage threshold less than a voltage produced by a defibrillation signal to permit effective conduction of the defibrillation signal along the implantable medical lead and to have a dielectric voltage threshold greater than a voltage induced by a magnetic resonance imaging (MRI) electromagnetic interference to inhibit conduction of the MRI electromagnetic interference along the implantable medical lead.
