Mechanical Characterization and Ex Vivo Evaluation of a Novel Constraining Device for Safe Endovascular Endograft Explantation.
OBJECTIVE Open surgical conversion after EVAR is morbid and performed without disease-specific instruments. We evaluated the feasibility, and mechanical characteristics of the EVAx, a novel single-use device designed to disengage, collapse, and constrain suprarenal aortic fixation barbs during open endograft explantati...
