Full textThis thesis deals with the design and engineering of a robotic assistant for percutaneous procedures with CT-scan visual feedback. CT-scan is commonly used by radiologists to manualy guide needles into tumors. While constantly checking the position of the needle, radiologists are repeatedly exposed to harmful X-rays. To cope with this issue, we propose a novel robotic system that will replace the arm of the radiologist for the initial alignment and while he holds the needle. The insertion task is split up in two complementary and mutually exclusive subtasks: the first is the positionning of the needle axis with an active robotic arm, the second is the insertion itself, currently done with a passive guide. From the specifications of the system, we define the kinematics of a parallel robotic arm with five degrees of freedom. The modeling of the structure is given: first the inverse and forward kinematics, then the velocity kinematics. Using these models, we have been able to characterize the workspace and the mobility of the device. Based on the computer aided design of the device, we describe the specific actuators, a realistic simulator and a position control algorithm with path planning for collision avoidance. In order to automatically position the needle with respect to a path specified in a CT-slice, a stereotaxic-like method to register a three-dimensional fiducial in the CT-scan reference frame is proposed. The registration is performed using a closed-form solution or an iterative method that can be further employed in an automatic matching algorithm. As a proof of feasibility, we finally show some experiments of automatic pointing of a target with a laser beam using CT-scan visual references. Similar experiments are also performed with a needle and an abdominal phantom in clinical conditions. Manual needle insertions with robotic guidance are performed on small targets in order to validate the accuracy and the robustness of the whole robotic system

Full textTranscatheter aortic valve implantation (TAVI) has emerged as an alternative to surgery for patients with severe aortic stenosis and high surgical risk. This technique is extending to a wider population (e.g. with more complex anatomy or lower surgical risk), as well as to patients with degenerated surgical bioprostheses (BPs). However, two major concerns remain limiting. Regarding “classical TAVI”, periprosthetic leaks have been associated with increased mortality. Oversizing is used to secure the device within the aortic annulus which is often non circular. The effects of oversizing and annulus shape on the hemodynamic performance are unknown. Regarding ViV implantations, elevated post-procedural gradients are common and have been associated with increased mortality. The principal factors associated with this residual stenosis as well as with increased risk of mortality, have been BPs label size ≤ 21 mm and mode of failure by stenosis. These factors are not specific enough and there is currently no recommendation for the treatment of small BPs. Besides, the actual hemodynamic benefit associated with ViV has not been evaluated (vs. pre ViV status).The general objective of this work is to understand the interactions between the transcatheter prosthesis and the aortic annulus or the BP to be treated, which impact the hemodynamic performance, especially in complex conditions of implantation, in order to extend the indications of TAVI. In the context of ViV, the objective is to specify the factors associated with the hemodynamic performance and utility of the treatment. The final aim is to provide strategies of implantation in order to optimize the success of the procedure

Esta tese propõe uma estratégia de guiagem robotizada de agulhas flexíveis com ponta chanfrada em procedimentos percutâneos. O método usa duty-cycle de rotação para realizar inserções com arco de curvatura ajustável e combina realimentação de imagem em malha fechada comuma estratégia intraoperatória de replanejamento de movimento para compensar incertezas e distúrbios no sistema. Diferentemente de estratégias anteriores, o replanejamento emmalha fechada é adequado a cenários dinâmicos emque há mudanças na posição do alvo e obstáculos. De fato, o sistema proposto foi implementado utilizando um robô manipulador, e os resultados obtidos de testes in vitro confirmaram a viabilidade do método. Até onde se sabe, tais resultados são originais, especialmente no que diz respeito ao uso de planejamento rápido intraoperatório combinado com duty-cycle da agulha e o uso de um braço manipulador disponível comercialmente. ______________________________________________________________________________ ABSTRACT
This thesis proposes a robot-assisted approach for automatic steering of flexible beveled needles in percutaneous procedures. The method uses duty-cycled rotation of the needle to performinsertion with arcs of adjustable curvature, and combines closed-loop imaging feedback with an intraoperative motion replanning strategy to compensate for system uncertainties and disturbances. Differently from previous approaches, the closed-loop replanning strategy is suitable for dynamic scenes that present changes of obstacles and target positions. Indeed, we implemented the proposed system using a robotic manipulator, and the results obtained from in vitro tests confirmed the viability of our method. To the best of our knowledge, such results are original, specifically in what concerns the use of an intraoperative fast replanning strategy combined with needle duty-cycling and the use of a commercially available manipulator arm. ___________________________________________________________________________________ RÉSUMÉ
Les travaux de cette thèse proposent une nouvelle approche pour le guidage assisté par robots d’aiguilles flexibles pour des procédures percutanées. La méthode est basée sur l’utilisation d’une rotation de l’aiguille avec un rapport cyclique variable pour réaliser une insertion avec des arcs de rayons de courbure différents. Elle combine un retour visuel avec une stratégie de planification adaptative pour compenser les incertitudes du système et les perturbations. Par rapport aux approches présentées précédemment dans la littérature, la stratégie de planification en boucle fermée est adaptée à des scènes dynamiques qui présentent des changements de position des obstacles et de la cible. Cette approche a été implémentée sur un système robotique et les résultats obtenus in vitro confirment tout l’intérêt de cette technique.

Full textThis work revolves around transcatheter aortic valve implantation (TAVI), which delivers a collapsible prosthesis to the native aortic valve through a delivery system (stiff guidewire and prosthesis sheath) inserted in an artery. This procedure became very popular ever since its introduction two decades ago. However, the performance of the treatment is correlated with the positioning of the prosthesis within the aortic root of the patient. Therefore, prediction of the spatial configuration of the prosthesis appears relevant data to assist pre-operative planning. It is assumed that the mechanical interactions between the delivery system and biological tissues determine the spatial configuration of the prosthesis. The thesis explores numerical simulation as a predictive tool. More specifically, the thesis attempts to numerically reproduce the deformations of the inserted stiff guidewire.A mechanical model was developed and translated into a Finite-Element model. The numerical prediction of the guidewire positioning within the aortic valve was validated with intra-operative data from two patient cases. The numerical model was also verified through an experiment using a 3D-printed patient-specific phantom. It was then exploited to choose a guidewire specifically suited for a patient

Full textCardiac electrophysiology procedures have been proved to be efficient to suppress arrythmia and heart failure symptoms. Their success rate depends on patient’s heart condition’s knowledge, including electrical and mechanical functions and tissular quality. It is a major clinical concern for these therapies. This work focuses on the development of specific patient multimodal model to plan and assist radio-frequency ablation (RFA) and cardiac resynchronization therapy (CRT). First, segmentation, registration and fusion methods have been developped to create these models, allowing to plan these interventional procedures. For each therapy, specific means of integration within surgical room have been established, for assistance purposes. Finally, a new multimodal descriptor has been synthesized during a post-procedure analysis, aiming to predict the CRT’s response depending on the left ventricular stimulation site. These studies have been applied and validated on patients candidate to CRT and ARF. They showed the feasibility and interest of integrating such multimodal models in the clinical workflow to assist these procedures
