Abstract
A device for capturing and removing an obstruction in a bodily duct of a patient. The device includes a cylindrical body having a circumference and a longitudinal axis. According to some implementations the cylindrical body is comprised of a plurality of closed cell structures arranged in diagonal rows around the longitudinal axis. At least some of closed cell structures have substantially the same shape and size. According to some implementations at least some of the closed cell structures of substantially the same shape and size occupy a same circumferential location in the cylindrical body and are longitudinally separated from one another by no less than two, three, four or more diagonal rows of closed cell structures. According to other implementations the closed cell structures include diagonally extending struts having at least a curve portion and a straight portion.
