A 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...
متن کاملMRI 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 کاملCyber-Physical Modeling of Implantable Cardiac Medical Devices
The design of bug-free and safe medical device software is challenging, especially in complex implantable devices that control and actuate organs in unanticipated contexts. Safety recalls of pacemakers and implantable cardioverter defibrillators between 1990 and 2000 affected over 600,000 devices. Of these, 200,000 or 41%, were due to firmware issues and their effect continues to increase in fr...
متن کاملDigital Investigation of Security Attacks on Cardiac Implantable Medical Devices
A Cardiac Implantable Medical device (IMD) is a device, which is surgically implanted into a patient’s body, and wirelessly configured using an external programmer by prescribing physicians and doctors. A set of lethal attacks targeting these devices can be conducted due to the use of vulnerable wireless communication and security protocols, and the lack of security protection mechanisms deploy...
متن کاملImplantable Cardiac Devices
Electrical cardiac pacing for the management of bradyarrhythmias was first described in 1952, and permanent transvenous pacing devices were introduced into clinical practice in the early 1960s. The first devices for endocardial defibrillation were implanted in surviving victims of sudden cardiac death in 1980. Implanted electrical devices for the management of cardiac dysrhythmias have changed ...
