Endovascular repair (EVAR) of an abdominal aortic aneurysm (AAA) involves the placement into the aneurysm of a stent graft (SG) by minimally invasive surgery. This procedure prevents rupture of the damaged tissue involved in an AAA, defined as a localized diameter dilation of the aorta. When the upstream portion of the aneurysm includes the peripheral renal and/or visceral arteries, the AAA is qualified as complex. In this case, the deployed SG is said “fenestrated”, in other words, perforated at the site of junctions to the peripheral arteries. Management of a complex AAA becomes more limiting as the fenestrated SG will be custom designed to match the anatomy of the aneurysm and the position of the peripheral arteries of the patient. This implies a manufacturing delay of several weeks, limits the management to stable aneurysms and excludes emergency situations. In this context, 3D printing (3DP) is of considerable interest for the fabrication of custom-made SGs in a very short time frame. Thus, the objective of this thesis work is to design a SG prototype by 3D printing of a medical grade thermoplastic polyurethane (TPU) (thermoplastic elastomer). The present work will validate the manufacturing process and the functionality of our 3DP-SG for its final application as an implantable medical device.First, the impact of the manufacturing process on the chemical, physical and physicochemical properties of TPU was studied at each step, from the pellets to the gamma-ray sterilization of a graft manufactured by fused filament deposition (FDM). In vitro preliminary evaluation of the cytotoxicity and hemocompatibility of TPU was carried out after the 3D printing and sterilization step. Aging of TPU under extreme oxidizing conditions was performed to predict the evolution of its properties in the long term. Subsequently, a design strategy for an endovascular implantable prototype was developed. The properties of said prototype were characterized by different techniques (SEC, TGA, DSC, FTIR, SEM, goniometry, uniaxial traction, ...). Its biological properties were evaluated in vitro by tests of cytocompatibility, hemocompatibility and contact with macrophages for 24 hours (acute inflammation). Moreover, the evolution of its physicochemical and mechanical properties was evaluated by in vitro aging studies.The characterization of the chemical, physical and physicochemical properties of TPU enabled the validation of a FDM printing manufacturing route and gamma ray sterilization of a crimpable SG prototype. The in vitro biological evaluation showed the non-cytotoxicity of the SG prototype by the extraction method. Moreover, the prototype was found to be weakly hemolytic and the platelets adhered on its surface were not activated. The low secretion of cytokines (IL-6 and TNF-α) upon contact with inactivated macrophages showed that the SG prototype does not exhibit a pro-inflammatory characteristic. Finally, aging studies showed an impact on the mechanical and surface properties of our SG prototype without compromising its functionality. Subsequently, the design strategy could evolve towards a functionalization of the SG prototype in order to prevent infections and thrombosis responsible for 2% and 6% of postoperative complications respectively

Abdominal aortic aneurysm (AAA) is a pathology that must be repaired by a surgical procedure to avoid a rupture, lethal in most of the cases. Endovascular aneurysm repair (EVAR) is a non-invasive procedure, allowing the deployment of a stent-graft inside the aneurysmal sac. Nevertheless, clinical feedback currently available for stent-grafts show that many complications after surgery – migrations, thrombosis, endoleaks, rupture – are closely linked to the mechanical behaviour of the stent-grafts, which is heterogeneous and very far from the one of the aorta. This behaviour is induced by the design of current stent-grafts, made by assembling a textile body with an exoskeleton sutured on the latter. These post-operative problems frequently lead to a second operation of the patient, which drastically reduces the benefits of endovascular surgery.In-vivo, stent-grafts are submitted to various loadings: inflation induced by the blood pressure, compression due to surrounding organs, but also bending due to the patient motion or the aorta tortuosity, etc. As far as possible, the mechanical behaviour of stent-grafts must also be as closed as possible to the original aorta, to avoid mechanical discontinuities that may be responsible for intimal hyperplasia.In this context, the principal purpose of this thesis is to contribute to the development and the optimization of vascular endoprostheses, resulting from an innovative manufacturing technology whose target is to insert a helical metallic wire in NiTi within a knitted PET textile body. This technology allows to build homogeneous textile tubes without any exo-skeleton. In order to optimize these structures, various experimental tests coupled with 2D or 3D imaging techniques – Synchrotron and laboratory X-ray micro-tomography – have been developed to characterize the mechanical behavior as well as permeability of these tubes. The results of these different tests are compared to experimental or numerical results of the literature regarding the native aortic tissue, as well as data concerning market products. The ultimate goal of this work is to provide new stent-grafts whose behavior is close to the native abdominal aorta, and which limit current post-operative problems

Every day the vascular textiles prostheses save lives. However, some localized ruptures were reported. In our laboratory, we have been characterising the polymer (polyéthylene téréphtalate) from which the vascular textile prostheses are made. We have been studying the organizations and the degradations of macromolecular chains. However, the organization of polymer and its physical aging depends on mechanical state of stress. Thus this thesis work was intended to provide new knowledge about the mechanical behaviour of textile structures and filaments. Given the fast that the standard mechanical tests are not representative, as to say, destructive and have little relation to physiological reality, we chose to develop a tear testing method with sinusoidal modulation of elongation. This method is coupled with monitoring the structural deformations using the image correlation technique to identify deformed arecs. Moreover, thermographie camera was coupled with the previous device to identify heavily constraining zones. The mono directional traction was used during these experiments. In order to investigate non-textile samples made of continuous polymer (TEFLON-PTFe), we build biaxial micro traction apparatus. Lt was used under electronic (MEB) and optical microscopes. These devices have pointed out on changes in the viscous behaviour of filaments at each loading level. It was confirmed by the thermo-mechanical data, as well. Our modulation method allowed us to discriminate a fibrous structure and showed that the textile structure can be quantifiable

Optical coherence tomography (OCT) is a high-resolution imaging technology particularly well-adapted for the study of the most superficial layers of the coronary artery wall and for stent assessment. In this book, we document our two year experience of OCT in the departement of cardiology of University Hospital, Clermont-Ferrand, France as well as the results of the OCT post-processing conducted by the ERIM team (Equipe de Recherche en Imagerie Médicale), of Auvergne University, Clermont-Ferrand, France. In the first chapter, the author details the principles behind OCT, the procedure itself and the indications for OCT examination. The feasibility and the limitations of OCT and image artefacts associated with this technology are also described using images from the author's registry of 301 OCT pull-backs. A second chapter is dedicated to the contribution OCT can make to the in-vivo analysis of coronary stents. Stent-optimization, follow-up assessment of the coronary after adverse events and clinical follow-up of drug-eluting stents are discussed with reference to recent publications and reported case-studies. The results of comparative analysis of differing neointimal coverage patterns between drug-eluting stents are also outlined and cross-referenced with others studies. In the third and final chapter, the author discusses recent material advances in OCT and in the post-processing of OCT images. He presents his own original computed analysis : in-vivo supervised analysis of stent coverage using optical coherence tomography. In conclusion, this work constitutes a reference-work for both the practical aspects of OCT and for critical analysis of OCT procedures. The author's experience of OCT is of benefit in correctly positioning this high-resolution technology in relation to the existing imaging methods. It confirms the considerable advantage OCT offers in the evaluation of vulnerable plaques and atheroma and in stent assessment. The contribution the work makes to the simplification of the procedure and to the standardization of image-analysis will also encourage the wider adoption of this promising technology as a complement to the other available imaging modalities
