A drug eluting angioplasty balloon (1, 101) suitable to adopt a deployed configuration and a collapsed configuration, the balloon having an outer wall (10) disposed around a core (11) defining an axis (X). The balloon (1, 101) comprising in the collapsed configuration a plurality of folds (12, 12', 112) that are laid in a tangential direction about the core (11) and form a plurality of cavities (13a, 13b, 113) loaded with a drug (14), the cavities (13a, 13b, 113) are comprised between the folds (12, 12', 112), wherein the folds (12, 12', 112) originates from distinct longitudinal lines (25, 25', 125, 125') along the outer wall (10), are arranged in pairs and are circumferentially wrapped about the core (11) in such a way that a fold of one pair overlaps an adjacent fold of another pair and are wrapped in opposite directions. |
