Texte intégralThe European Directive 2013/ 35 / EU specify minimum requirements for the protection of workers exposed to electromagnetic fields and define with implants as “workers at particular risk”. Regarding the implantable cardioverter defibrillator wearers (ICD) or pacemaker (PM), exposure to electric or magnetic field of extremely low frequency creates inductions inside the human body that generate interference voltage which may cause the dysfunction of the implant. This thesis investigates the electromagnetic compatibility of cardiac implants subjected to an electric field low frequency (50/60 Hz). Computational simulations are effectuated in order to design an experimental bench for the exposure of a phantom including pacemakers or implantable defibrillators. A provocative study is established to define the electric field thresholds for preventing any malfunction of the implant. In numerical simulations; a virtual human model (digital phantom containing a cardiac implant) was placed in an upright position in a vertical exposure to an electric field. The finite element method was used to define the inductions in the cardiac implant level with a resolution of 2 mm (CST® software). In the experimental part, a test bench designed to allow generating an electric field up to 100 kV / m at frequencies 50-60 Hz was constructed, optimized and employed to investigate the behavior of cardiac implants.Several configurations were studied. 54 active cardiac implants (43 pacemakers and 11 defibrillators) are submitted to very high electric field of 50-60 Hz (up to 100 kV / m) inside the experimental bench. No failure was observed for public exposure levels for most configurations (+ 99%) except for six pacemakers in the case of a configuration clinically almost inexistent: unipolar mode with maximum sensitivity and atrial sensing.The implants configured with a nominal sensitivity in bipolar mode are resistant to electric fields exceeding the low action levels (ALs), even for the most high ALs, as defined by 2013 / 35 / EU

Texte intégralTargeting cardiology diagnosis and treatment, active implantable medical devices (AIMDs) have been rapidly developed and widely applied with constantly updated technologies in recent decades. It is vital for scientific research to catch up with the speed of the information era in terms of the side effects on human beings and the environment. Pacemakers (PMs), used for the treatment of arrhythmias (bradycardias and tachycardias), and implantable cardioverter defibrillators (ICDs), for palliating serious ventricular arrhythmias by electric shocks to the myocardial tissue are important AIMDs normally implanted in the human chest. Electromagnetic radiation is inevitable present in our surroundings and raised many questions concerning the potential effects on the AIMD-wearers. The increasing number of medical implant wearers, including those in active professional activities, has led to questions regarding their performance in the presence of an occupational electromagnetic field (EMF) exposure. Since the 1960s, these questions have concerned possible interference linked to the energy transport network. The frequencies allocated to electrical energy (50 Hz and 60 Hz) are in the analysis bandwidth of the cardiac signals, of which spectrum extends from a few Hertz to approximately 150 Hz. The AIMDs are usually equipped with selective filters enabling to significantly reduce or eliminate the interference. However, considering the nature formation of the heart signals, 50 Hz and 60 Hz may not be filtered in order to ensure the cardiac signal waves are correctly and completely sensed.In the workplaces, it is inevitable to have the existence of workers who are susceptible to the electromagnetic field (EMF)-related impact. The presence of workers wearing AIMDs is then to be considered as specific cases. In other words, particular attention should be given to AIMD carriers who are subject to higher risks and corresponding risk evaluation process should be established. The procedure for assessing the EMF exposures for workers bearing AIMDs was proposed in EN 50527 to determine the risk arising from the exposures in the workplaces. Immunity test on AIMDs is critical in the risk assessment procedure and requires a simple, feasible, and risk-free test method. To date, the electric field exposures at low frequencies has received little attention yet they commonly exist in the workplaces in electrical industries, for example, area near power lines and substations. In this study, high-intensity electric field exposures are mainly concerned. The frequency band was limited to extremely low frequency at 50 Hz to focus on the occupational exposures caused by power sources.The interference can be evaluated by the estimation of the induced voltage at its input. Equivalent systems can be built up by adopting this conception to reproduce the exposures and the implantation conditions in order to generate same effects at the input of cardiac implant (same induced voltage). In this work, a theoretical and experimental study was performed on an in vitro phantom that allowed to determine the voltage induced at the input of a cardiac implant subjected to a high-intensity electric field at 50 Hz. The phantom is composed of two parts with electrical characteristics similar to those of the human heart and the chest, where the cardiac lead and the housing are implanted. Experimental measurements and numerical simulation are coherent which validates the equivalence factors we found for our systems. Thus, the in vitro phantom can be applied as an equivalent system in the workplace for the immunity test on cardiac implants. Another result we established in this study is the equivalence between an electric field exposure system and an injection system which allows us to reduce the complexity of the study, and conduct simpler tests with reproduced perturbations

Texte intégralActive cranial implants are more and more developed to cure neurological diseases. In this context it is necessary to evaluate the mechanical resistance of the skull-implant complex under impact conditions as to ensure the patient’s security. The aim of this study is to quantify the mechanical interactions between the skull and the implant as to develop a finite element model for predictive purpose and for use in cranial implant design methodologies for future implants. First, material tests were necessary to identify the material law parameters of titanium and silicone. They were then used in a finite element model of the implant under dynamic loading, validated against 2.5 J-impact tests. The implant dissipates part of the impact energy and the model enables to optimize the design of implants for it to keep functional and hermetic after the impact. In the third part, a finite element model of the skull-implant complex is developed under dynamic loading. Impact tests on ovine cadaver heads are performed for model validation by enhancing the damage parameters of the three-layered skull and give insight into the behavior of the implanted skull under impact.This model is a primary tool for analyzing the mechanical interaction between the skull and an active implant and enables for an optimized design for functional and hermetic implants, while keeping the skull safe
