My buddy, my friend: focused force angioplasty using the buddy wire technique in an inadequately expanded stent.

Progressive minituarization of angioplasty hardware has resulted in a reduction of access site complications. This has limited to some degree the equipment used with small delivery systems. The buddy wire technique is a potential solution for resistant lesions with an underexpanded stent that can be used without having to upsize the introducer and guiding catheter.
