  • Patent number: 12070612
    Abstract: A magnetic field sensor is positioned in proximity to a charging coil in an implantable medical device (IMD). An external device for charging the IMD includes a primary coil and a magnet positioned in proximity to the primary coil. The magnetic field sensor in the IMD detects a static magnetic field of the magnet and provides measurements proportional to the static magnetic field along three axes. These measurements of the static magnetic field are used to determine whether the external device is aligned with the IMD for charging. These measurements of the static magnetic field may also be processed to determine a position of the charger device relative to the IMD in three dimensions. When misaligned, a direction may be generated for a user to reposition the charger device to improve alignment.

  • Patent number: 11904159
    Abstract: A method of forming a stimulation lead includes forming an implantable lead body, including helically winding at least one cable about a mandrel to form a coiled cable assembly in a first, restrained state. Helically winding the at least one cable includes applying a tensile force to the at least one cable as the at least one cable is wound about the mandrel. Forming the lead body also includes releasing the tensile force from the at least one cable to allow the coiled cable assembly to release stored mechanical energy and transition from the restrained state to a second, relaxed state in which the coiled cable assembly is substantially free of stored mechanical energy. The method further includes subjecting the lead body to a reflow process by applying heat to the lead body, where the tensile force is released prior to the lead body being subjected to the reflow process.
