Patent number: 8326436Abstract: Systems and methods for improving response of implantable leads to magnetic fields during medical procedures such as magnetic resonance imaging (MRI) are described. In various embodiments, the lead includes an inner conductor that is helically shaped and radially surrounded, at least in part, by one or more high-voltage conductors. The high-voltage conductor can be mechanically and/or electrically coupled, via a coupler, to the shocking coil. The pitch of the inner and/or outer conductor can be varied (e.g., continuously or at certain points) along the length of the lead. In some embodiments, the filar thickness, the pitch, and the mean coil diameter of the inner coil, the high voltage conductor coil, and the shock coil can be configured such that these coils have a desired inductance value when subjected to externally applied electromagnetic energy at radio frequencies commonly generated by MRI scanners (e.g., 40 MHz to 300 MHz).Type: GrantFiled: February 18, 2011Date of Patent: December 4, 2012Assignee: Cardiac Pacemakers, Inc.Inventors: Yingbo Li, Masoud Ameri, G.

Patent number: 8271097Abstract: Various embodiments relating to MRI safe, multi-polar active fixation stimulation leads with co-radial construction are disclosed. Some embodiments, allow the use of the generally smaller diameter co-radially constructed body (coated wires) to construct an active fixation lead, with an extendable/retractable fixation mechanism. Some embodiments use a connector assembly with an inner terminal ring, a terminal pin partially rotatably positioned within the annular inner terminal ring, and one or more resilient C-clips disposed within circumferential recesses. The resilient C-clips mechanically and electrically couple the inner terminal ring and the terminal ring while substantially limiting relative longitudinal translation of the terminal pin.Type: GrantFiled: October 19, 2010Date of Patent: September 18, 2012Assignee: Cardiac Pacemakers, Inc.Inventors: Arthur J.
