Angioplasty balloon with reduced diameter in its proximal part and broadening in its middle part

摘要

the reduced diameter part of the balloon angioplastyczny proximal and enlargement in the middle part, built three interlocking parts of different diameters, designed to carry out treatments of vascular and coronary angioplasty bubble, especially in places bifurkac ji, is suchthe proximal part (1) has a reduced diameter relative to the diameter dp dd distal parts (3), whereby the diameter ratio dp part (1) to the proximal diameter dd of the distal (3) ranges from 0.25 to 0.75, and the middle part (2) extending between a spherical the extreme parts (1, 3) with a maximum diameter greater than the diameter of the ds, dd distal parts (3),the ratio of maximum diameter for the central part (2) to the diameter dd of the distal (3) ranges from 1.1 to 1.5.
