Abstract
An angioplasty balloon (1) comprises an elongate tube (16) having a relaxed delivery configuration and an expanded deployed configuration. The elongate tube (16) comprises a proximal neck portion (10), a distal neck portion (8), a main body region, a tapered proximal portion (11) extending between the main body region and the proximal neck portion (10); and a tapered distal portion (9) extending between the main body region (3) and the distal neck portion (8), the elongate tube has only three fins (4, 5, 6) which are integrally formed with the tube and which are spaced equidistant from one another about the exterior of the tube. The fins (4, 5, 6) project radially outwardly from the exterior surface of the tube and the fins (4, 5, 6) extending longitudinally only along part of the main body region (3), resulting in the end-sections of the balloon main body being fin-free.
