Abstract
Abstract Kits for use in the treatment of vascular calcified lesions are provided. The subject kits include at least one of: (a) a fluid delivery means for conveying fluid to and from a vascular site; and (b) a dissolution fluid for at least partially dissolving the target lesion. In many embodiments, the kits include both of these components. The subject kits further include instructions for treating vascular calcified lesions with the contents of the kit, where the instructions are typically recorded on a recording medium, e.g. printed on a substrate, such as paper.
