Claim Text:
1. A method of producing a device for restoring blood flow to an occluded blood vessel, comprising: cutting a stock of a biocompatible material in a pattern that, when said material is formed into a substantially cylindrical shape, said material forms a self-expandable treatment portion capable of being shifted between a compact delivery configuration and an expanded treatment configuration; wherein said self-expandable treatment portion comprises a cage formed of a plurality of interconnected cage struts that form a series of substantially diamond-shaped repeat units along a long axis of said cage when said self-expandable treatment portion is in said expanded treatment configuration; wherein said self-expandable treatment portion comprises a wave-like side profile having crests and valleys formed by said plurality of interconnected cage struts, wherein said wave-like side profile has a crest-to-valley distance of between about 0.1 mm and about 8.0 mm; wherein corners of said diamond-shaped repeat units are configured to capturingly engage a portion of said occlusion for removal from said blood vessel; wherein, when said cage is in said expanded treatment configuration, a proximal end portion of said cage converges inwardly to form an elongate tubular connection member extending outwardly and substantially coaxially with a long axis of said self-expandable treatment portion; forming a bulbous terminal portion on a terminal end portion of a delivery wire after said terminal end portion has been advanced through said tubular connection member; attaching said bulbous terminal portion to said tubular connection member within the interior of said self-expandable treatment portion; and attaching a radiopaque material body proximal to said proximal end portion of said self-expandable treatment portion.
