摘要： An apparatus for applying a signal to a nerve for the treatment of a disorder includes a main electrode body of biocompatible dielectric material and having a concave upper surface and an opposite lower surface. The concave upper surface curves about an axis and has a curvature sized to receive a nerve within the concave surface with an axis of the nerve substantially parallel to an axis of the concave surface. An electrode contact of electrically conductive material is secured to the main electrode body and has an electrode contact surface exposed on the concave surface. The concave surface terminates at opposite first and second upper ends. The electrode contact has a first end near the first end of the concave surface. A secondary electrode body of biocompatible dielectric material is attached to the first upper end of the concave surface. An electrode lead has an electrical conductor surrounded by a biocompatible insulative coating with both the conductor and the coating flexible relative to a longitudinal axis of the lead. A first end of the lead is secured to the secondary electrode body and with a first end of said conductor electrically connected to said first end of said electrode contact.

摘要： A conductor assembly for a medical device lead includes a helically coiled conductor including a plurality of turns having a coil pitch and an outer diameter and consisting of one filar having a filar diameter. The coil pitch and outer diameter are selected based on the filar diameter to minimize heating of the helically coiled conductor in the presence of an MRI field. A polymer sheath is formed about the helically coiled conductor such that the coil pitch of the unifilar helically coiled conductor is maintained. The polymer sheath is configured to increase a torque transmitting capacity of the helically coiled conductor.

摘要： Implantable medical devices and associated methods are disclosed. In one implementation, the implantable medical device comprises a conductive housing and a remote electrode that is mechanically coupled to the conductive housing by a lead body. An amplifier is electrically connected to the remote electrode and the conductive housing for providing a signal representative of a voltage difference between the remote electrode and the conductive housing. In some methods in accordance with the present invention, the implantable medical device is implanted in an implant site overlaying one half of a rib cage of a human body. The implantable medical device produces a signal representative of the voltage difference between the remote electrode and the conductive housing and the signal is transmitted to a receiver located outside the human body.

摘要： An implantable medical lead exhibits reduced heating under MRI conditions. The lead includes a multi-layer coil conductor including an inner coil layer, a middle coil layer disposed around the inner coil layer, and an outer coil layer disposed around the middle coil layer. Each of the coil layers is characterized by one or more of a filar thickness, a coil pitch, or a coil diameter configured such that the coil conductor exhibits a high inductance when exposed to MRI radiation. Each of the coil layers is electrically connected to the other coil layers to provide parallel conductive paths resulting in a coil conductor resistance suitable for defibrillation lead applications.
