MRI compatibility and visibility assessment of implantable medical devices.
We have developed a protocol to evaluate the magnetic resonance (MR) compatibility of implantable medical devices. The testing protocol consists of the evaluation of magnetic field-induced movement, electric current, heating, image distortion, and device operation. In addition, current induction is evaluated with a finite element analysis simulation technique that models the effect of radiofreq...
متن کاملEvaluation of MEMS materials of construction for implantable medical devices.
Medical devices based on microelectro-mechanical systems (MEMS) platforms are currently being proposed for a wide variety of implantable applications. However, biocompatibility data for typical MEMS materials of construction and processing, obtained from standard tests currently recognized by regulatory agencies, has not been published. Likewise, the effects of common sterilization techniques o...
متن کاملPOKs Based Low Energy Authentication Scheme for Implantable Medical Devices
Implantable medical devices (IMDs), including pacemakers, implanted cardiac defibrillators and neurostimulator are medical devices implanted into patients’ bodies via surgery and are capable of monitoring patient’s conditions and delivering therapy. They often have built-in radio modules to support data reading and parameters reconfiguration according to the commands from external programmers. ...
متن کاملA temperature sensor implant for active implantable medical devices for in vivo subacute heating tests under MRI.
PURPOSE To introduce a temperature sensor implant (TSI) that mimics an active implantable medical device (AIMD) for animal testing of MRI heating. Computer simulations and phantom experiments poorly represent potential temperature increases. Animal experiments could be a better model, but heating experiments conducted immediately after the surgery suffer from alterations of the thermoregulatory...
