This review describes current research and recent developments in four interventional devices for the treatment of peripheral arterial disease. Balloon dilatation systems have evolved, with balloon catheters that are smaller, more flexible, and less traumatic. Laser technology has continued to develop, although its long-term clinical efficacy remains unproven. Laser developments include the encapsulation of fiber optics within a metal cap and coaxial centering of the laser beam within the arterial lumen, to prevent perforation or dissection of the vessel. Atherectomy devices used to recanalize occlusive lesions with and without the use of a guide wire are being scrutinized and evaluated. Technological advances in intravascular stents, (eg, higher expansion ratios and coatings) will expand the role of this device. Stents represent a very major development for the treatment of vascular diseases in general. Research in endovascular devices has greatly expanded the application of nonsurgical revascularization, which was at one time limited to crude balloon angioplasty. Although some devices have limited application, technological advances will likely expand the role of interventional therapies for the treatment of peripheral arterial disease.
