  • Publication number: 20140073194
    Abstract: An IS-4 terminal connector assembly includes three terminal electrodes positioned over an inner tubular member such that they are radially offset from one another. Each of the terminal ring electrodes are configured such that they can withstand both tensile and cyclical bending loads with minimal compromise in their outer geometry. Additionally, each of the terminal electrodes is configured such that they have both an inner and outer geometry that facilitates adequate insulation between a select terminal electrode and an adjacent conductor. Additionally, each of the terminal ring electrodes is configured such that they facilitate an external approach to staking a cable conductor.

  • Publication number: 20140067030
    Abstract: Various embodiments concern leads having low peak MRI heating for improved MRI compatibility. Various leads include a lead body having at least one lumen, a proximal end configured to interface with an implantable medical device, and a distal end. Such leads can further include a conductor extending along at least a portion of the lead body within the at least one lumen and a defibrillation coil extending along an exterior portion of the lead body and in electrical connection with the conductor, wherein at least a section of the defibrillation coil is under longitudinal compression. The longitudinal compression can lower peak MRI heating along the defibrillation coil. The longitudinal compression may maintain circumferential contact between adjacent turns of the section of the defibrillation coil.
