Filter by:The purpose of this study is to demonstrate that the Endurant Evo Abdominal Aortic Aneurysm (AAA) stent graft system is safe and effective for endovascular treatment of infrarenal abdominal aortic or aortoiliac aneurysms.
The objective of the study is to assess the incidence of safety outcomes in patients treated with Pipeline™ Flex embolization device with Shield Technology™.
The main objective of this study is to utilize Magnetic Resonance Elastography (MRE) to determine tissue stiffness of abdominal aortic aneurysms (AAA). For patients with AAA, MRE is a more sensitive and superior method of determining the risk for rupture of AAA based on stiffness estimates when compared to the current, crude method of assessing risk based on measurement of the diameter of the aneurysm. The investigators will also validate the stiffness estimates against gold standard i.e. mechanical testing and histopathology only AAA patients undergoing AAA surgery.
The purpose of the study is to investigate if briefly stopping blood flow to the patient's leg will lead to the patient's body being better able to tolerate possible decreased blood flow to regions of the brain which otherwise frequently happens after subarachnoid hemorrhage. Previous studies show that various organs such as the heart, brain or kidney can tolerate longer periods of decreased blood flow if prior to that insult shorter periods of decreased blood flow were experienced.
This study will analyse factors contributing to cardiac re-operation to determine causative effects
The purpose of this study is to produce a patient-specific simulator for endovascular infra-renal aneurysm repair training and than analyze the effect of simulator training on the performance of vascular surgery residents.
The purpose of the Feasibility study is to characterize the safety of the Valiant Mona LSA Thoracic Stent Graft System, including an assessment of the safety and effectiveness of the device acutely and at the 30 day visit in the identified subject population. This study will also evaluate the current instructions for use and may direct changes to the delivery and deployment steps. The purpose of the expansion to the Feasibility Study is to characterize the Valiant Mona LSA Thoracic Stent Graft System, in particular to assess the safety and effectiveness of the device acutely and at the 30 day visit, in subjects enrolled with chronic, Type B dissections.
A multicenter, prospective, open-label, non-randomized, interventional clinical study, sponsored by Endospan Ltd. Patients will be followed-up for five years.
Flow diverters have been approved since 2012 for the treatment of large, wide neck intracranial aneurysms. These devices have been associated with embolic events which cause blockage in a blood vessel and can result in long term complications. One possible cause of these events is the formation of small emboli during placement of the device.
To determine FDG uptake following uncomplicated EVAR using the Nellix endoprosthesis. Does uncomplicated EVAR using the nellix endoprosthesis result in increased FDG uptake and false positive PET imaging?
