    摘要: Energy delivered from an implantable medical device to stimulate tissue within a patient's body is controlled. An electrical signal used to stimulate the tissue is changed from a first energy state to a second energy state during a magnetic resonance imaging (MRI) scan. The energy delivered is maintained at the second energy state after the MRI scan. A capture threshold of the tissue is then measured, and the energy delivered to the tissue is adjusted based on the measured capture threshold of the tissue.

    摘要: A system and method for providing fault resilient processing in an implantable medical device is provided. A processor and memory store are provided in an implantable medical device. Separate times on the processor are scheduled to a plurality of processes. Separate memory spaces in the memory store are managed by exclusively associating one such separate memory space with each of the processes. Data is selectively validated prior to exchange from one of the processes to another of the processes during execution in the separate processor times.

    摘要: An implantable medical apparatus comprises a solid state electronic circuit, an ionizing radiation exposure sensor, an ionizing radiation dose rate sensor, and a controller circuit. The ionizing radiation exposure sensor is configured to detect an exposure of the solid state electronic circuit to ionizing radiation, and generate an indication of a non-single-event-upset (non-SEU) effect to the solid state electronic circuit from the exposure to ionizing radiation, wherein the sensor comprises an accumulated ionizing radiation exposure sensor. The controller circuit is configured to blank the indication from the accumulated ionizing radiation exposure sensor when the radiation dose rate sensor indicates that flux ionizing radiation exceeds a flux ionizing radiation threshold.

    摘要: This document discusses, among other things, an inductive component that can include a core having two portions: (1) a first portion composed of a first material having a first magnetic saturation level; and (2) a second portion composed of a second material selected to provide inductance for the inductive component when an external magnetic field is greater than the first magnetic saturation level. In an example, the first portion can be composed of a material having a relatively low magnetic saturation level (e.g., a ferrite), and the second portion can be composed of a material having a relatively high magnetic saturation level (e.g., a high permeability iron alloy).

    摘要: A medical device lead includes an insulative lead body, outer and inner conductive coils, and a flexible core assembly. The outer conductive coil extends through the lead body and is coupled to a first electrode at a distal end of the outer conductive coil. The inner conductive coil extends coaxially with the outer conductive coil, is coupled to a second electrode at a distal end of the inner conductive coil, and includes a central lumen. The flexible core assembly is disposed in the central lumen and is comprised of a material that has a saturation magnetization of at least about 1.5 T and a relative permeability of greater than one. The flexible core assembly includes a positioning interface configured for manipulation of the flexible core assembly such that the flexible core assembly translates through the central lumen during insertion and extraction of the flexible core assembly.

    摘要: To provide a positive indication that a medical lead terminal is properly secured within the longitudinal bore in the header of an implantable medical device there is provided a force sensor (strain gauge) positioned within the device's lead receiving bore and cooperating with the lock mechanism to provide an indication of the amount of force being exerted on the lead terminal to retain it in place. The force sensor provides an output signal through the device's feedthrough wires to the electronic circuit contained within a hermetically sealed housing and is compared by a microprocessor to preprogrammed values. The results of the comparison may then be telemetered to an external programmer device for analysis by a physician.

    摘要: A system and method of enabling detection enhancements selected from a plurality of detection enhancements. In a system having a plurality of clinical rhythms, including a first clinical rhythm, where each of the detection enhancements is associated with the clinical rhythms, the first clinical rhythm is selected. The first clinical rhythm is associated with first and second detection enhancements. When the first clinical rhythm is selected, parameters of the first and second detection enhancements are set automatically. A determination is made as to whether changes are to be made to the parameters. If so, one or more of the parameters are modified under user control.
