摘要： An improved system for monitoring the status of an IMD such as medical electrical lead during an implant procedure is provided. The system includes a signal generator for supplying a first signal such as a constant current or voltage to the IMD. A resulting voltage or current signal is generated, respectively, and may be sensed as an indication of the impedance of a portion of the body that is proximal to one or more electrodes carried by the lead. This impedance indication is converted to an audible signal having a frequency that is proportional to the amplitude of the impedance indication. The pitch of the audible signal therefore rises when measured impedance increases, and drops as the impedance decreases. These pitch changes allow a user to determine positional information associated with the IMD, including the degree of lead tissue contact and extent of fixation of a device to tissue.

摘要： An implantable electrical lead having at least two mutually insulated electrical components (30, 38) that are separated by a portion of the lead's body fabricated of a pliant, extensible biocompatible insulated material. An extensible conductor (44) extends from the proximal end of the lead body to a first one of the electrical components, and a second, inextensible conductor (42) extends from the proximal end of the lead body to a second one of the electrical components. An inextensible reinforcement member (50) is coupled to the inextensible conductor and extends distally from the second electrical component to the first electrical component and is coupled mechanically to the first electrical component.

摘要： An implantable medical device system including an implantable electronic device having multiple electrical connectors and an associated electrical lead also having a corresponding set of electrical connectors which engage with the connectors on the device. The lead has a connector assembly mounted to its proximal end, including the lead's electrical connectors and a mechanical connector. The device has a connector block with a bore extending therethrough sized to receive the connector assembly of the lead. A pulling tool is provided for pulling the lead connector assembly proximally in the bore of said connector block from a first position in which the lead's connector assembly is not fully inserted in the connector block to a second position in which said connector assembly is fully inserted in the connector block, the pulling tool being provided with a mechanical connector which engages with mechanical connector on the lead's connector assembly.
