AORTIC STIFFNESS MODIFICATIONS AFTER ENDOVASCULAR AORTIC REPAIR
Background: Endovascular aortic repair (EVAR and TEVAR) has transformed the management of aortic aneurysms and dissections through its minimally invasive approach and favorable short-term outcomes. However, concerns regarding the long-term cardiovascular implications of endograft implantation have …

Patient-specific thoracic endovascular aoratic repair (TEVAR)
Endovascular aortic repair (EVAR) is a minimally invasive procedure to treat aortic aneurysms. Current off-the-shelf devices may not fit the patient perfectly, potentially increasing the chance of post-operative complications. This project aims to provide proof of concept for rapidly creating …

Semi-autonomous Magnetic Manipulation for Endovascular Navigation
Endovascular navigation is one of the significant barriers to stroke treatment. Due to its geometrical complexity, navigation inside the cerebral arteries becomes challenging as the destination moves further toward the distal region of the brain. Magnetic manipulation is one solution that can …
