Claim:
1. An angioplasty balloon configured to adopt a deployed configuration, a semi-deployed configuration, and a collapsed configuration, the angioplasty balloon comprising: an outer wall; a core defining an axis (X); a plurality of laps formed by the outer wall when the angioplasty balloon is in the collapsed configuration, wherein the plurality of laps are laid in a tangential direction about the core of the angioplasty balloon to form a plurality of cavities, wherein the plurality of cavities are filled with a drug; and wherein the angioplasty balloon further comprises a distal shaped portion located distal of a central length of the angioplasty balloon containing the plurality of laps of the angioplasty balloon, wherein the distal shaped portion and the central length of the angioplasty balloon are in fluid communication with each other; wherein the central length and the distal shaped portion of the angioplasty balloon are both larger when the angioplasty balloon is in the deployed configuration than when the angioplasty balloon is in the collapsed configuration, and wherein the distal shaped portion has a maximum radial dimension when the angioplasty balloon is in the deployed configuration and the semi-deployed configuration, and further wherein the central length of the angioplasty balloon containing the plurality of laps adopts an intermediate radial dimension smaller than the maximum radial dimension of the distal shaped portion when the angioplasty balloon is in the semi-deployed configuration.
