Use of the Boomerang catalyst™ advantage closure device to facilitate complex multistaged percutaneous revascularization procedures for the treatment of critical limb ischemia

An increasing spectrum of complex peripheral arterial disease may be successfully treated using percutaneous revascularization techniques. A pair of challenging peripheral revascularization procedures in patients with critical limb ischemia is presented, where an array of interventional tools and techniques were required, and the off-label use of the Boomerang catalyst system closure device was important in managing a variety of complex arterial access issues and ultimately allowing procedural success.
