Filter by:An in-house calculator was developed to calculate the appropriate contrast dose, rather than standardly administering a 120ml dose. This study aims for a more uniform contrast enhancement in patients by means of adjusting (lowering) contrast dose to patient parameters.
To establish the preliminary safety and effectiveness of the SEAL™ Endovascular Aneurysm Lattice System for the treatment of saccular intracranial aneurysms. The data from this study will be used to support: 1. EU CE Mark labelling 2. US FDA Investigational Device Exemption (IDE) approval support of PMA approval.
This project seeks to determine if certain anatomic factors, specifically tortuous and non-conformable iliac arteries, may predict device complications, including seal zone failure, type III endoleak, and occlusion. Approximately 400 subjects from 5 academic centers across the United States, Europe, and Asia will be included in this study. Various markers of pre- and post-treatment iliac anatomy will be measured using CT imaging, and clinical events will be reported by academic centers. The relationship of imaging data to patient demographics will then be assessed alongside anatomic and demographic predictors of non-conformability.
Objective Complex aortic pathology has been revolutionized with the use of hybrid prostheses such as the Thoraflex® Hybrid Frozen Elephant Trunk (FET). The aim of this study was to evaluate the midterm results of secondary extension of the FET by thoracic endovascular aortic repair (TEVAR). Few data are present in the literature regarding the outcomes of this secondary treatment. The investigators perform a prospective study between 2015 and 2022 in a tertiary aortic center on all consecutive patients having undergone TEVAR after FET implantation. The TEVAR endograft covered most of the 10 cm FET module with 2 to 4 mm oversizing. All patients were monitored by computerized angiography (CTA) at 6-month and yearly thereafter. The aim of this study was the feasibility of theses secondary connexion and the mid term outcomes of the endovascular treatment.
The purpose of this PMCF study is to evaluate a minimum of 125 subjects in 1 or 2 sites in France at least 1-year follow-up after surgery until a maximum of 5 years in the indication of abdominal and peripheral arterial surgery not crossing the knee flexion crease. the objectives of the evaluation will describe safety and performance of POLYMAILLE® EXTRA THIN.
Purpose of the study is to describe safety and performance of POLYMAILLE® C from a minimum of 200 subjects will be evaluated. A minimum of 100 subjects will be evaluated for each main location of surgery (abdominal and peripheral). Follow-up At least 1 year follow-up after surgery until a maximum of 5 years. POLYMAILLE®C vascular prostheses are indicated for replacement or bypass of arteries presenting aneurysm or obliterative arterial disease. Their indication is restricted to abdominal and peripheral surgery not crossing the knee flexion crease.
Retrospective observational study of all patients undergoing aortic root surgery with aortic valve conservation, using the inclusion technique described by Tirone David, between January 1, 2004 and December 31, 2020, at six centers (Nantes - Rennes - Brest - Angers - Tours [two centers]). The main objective of this study is to evaluate the survival without re-intervention for aortic valve dysfunction (surgery or TAVI).
Post Marketing Surveillance of the Conformable GORE® TAG® Thoracic Endoprosthesis
To assess the expression of miRNA in patients with TAA, AAA in aneurysmatic tissue and to compare this expression with the healthy tissue in the same patient. In the same cohort, to asses the presence of miRNA in plasma and to compare with the control group. Over the period of three years,to follow subjects in order to assess if the presence of certain miRNAs speeds up or slows down the progression of disease. In patients with intracranial aneurysms to detect miRNA in plasma especially in patients with familial occurrence.
The objective of this clinical investigation is to evaluate the safety and technical success of the Basecamp Vascular controllable directional GECKO guidewire when used to facilitate endovascular access to the targeted vessel in order to treat the vascular lesion.
