Abstract

Embodiments include an implantable device configured to be used in an MRI device, including a control unit, a memory unit, an MRI sensor and a statistics unit. The memory unit includes program information including control programs and/or control parameters that control the function of the control unit, and current state parameters. The MRI sensor is connected to the control unit and responds to a positioning of the implant and/or a patient within or in the immediate vicinity of the MRI device. The statistics unit is connected to the control unit and detects current state parameters present prior to a respective response of the MRI sensor. The control unit selects a control program or control parameters indicated by the state parameters and maintains the control program or control parameters until the MRI sensor indicates a positioning of the implantable device within or in the immediate vicinity of the MRI device.
