Abstract
A system and method for treating critical limb ischemia (CLI) including a radiopaque micro stent disposed for cross ankle stenting as well as retrograde pedal/tibial artery access, in conjunction with antegrade access for the recanalization of impaired tibial vessels. A radiopaque medical device is constructed from a tubular-shaped body having a thin wall defining a specific strut pattern. In an additional aspect, the present apparatus introduces a new radiopaque medical device, such as a stent, wherein the tubular body includes a super elastic, nickel-titanium (nitinol) alloy.
