Abstract
An elongate embolectomy device having a radially constrained configuration and a radially expanded configuration, the embolectomy device being formed out of a plurality of elongate clot engaging structures, each clot engaging structure comprising a plurality of interconnected struts forming an open cell pattern, wherein, when the embolectomy device is in the radially expanded configuration, the clot engaging structures each have a semi-tubular arcuate profile, including a convex face and an concave face facing opposite the convex face, extending along a length of the embolectomy device, the clot engaging structures being longitudinally disposed relative to each other such that the concave faces are facing radially outward, and the convex surfaces are facing radially inward, respectively, relative to a longitudinal axis of the embolectomy device.
