1. An embolic capture device comprising:
an elongated stent body having a distal end, a proximal end, an axial lumen extending from the distal end to the proximal end, and a luminal surface;
at least two connecting struts at the proximal end of the stent body joined together with a distal end of a pusher shaft;
wherein the luminal surface of the elongated stent body has a plurality of cells; and each cell of the plurality of cells has a distal end, a proximal end, and a cell axis extending through both distal and proximal ends;
wherein a first circumferential row of cells of the plurality of cells along the luminal surface of the elongated stent body have a first cell axis forming a first angle with a longitudinal axis of the stent body, and a second circumferential row of cells of the plurality of cells adjacent to the first circumferential row of cells having a second cell axis forming a second angle with the longitudinal axis of the elongated stent body; and the first and the second angles are different; and
wherein the embolic capture device has a radially collapsed profile during delivery and a radially expanded profile upon deployment, and
wherein as the device resumes its radially expanded profile, the first
circumferential row of cells rotates around the longitudinal axis of the stent body in a first direction, and the second circumferential row of cells rotates around the longitudinal axis of the stent body in an opposite direction, wherein one of the first direction and the opposite direction is clockwise.
