Abstract:
1. Intravertebral widening device for kyphoplasty extending from a proximal end to a distal end along an extension axis, said distal end comprising an elastically deformable element, suitable to pass from a relaxed configuration for the positioning of the distal end within a vertebral body to a deformed configuration to form a cavity within said vertebral body, wherein said elastically deformable element comprises at least one tab having, along its longitudinal extension, a thickness, as measured relative to a radial direction incident to said extension axis and contained in a perpendicular plane to said extension axis, variable along the axis such as to vary the stiffness of at least one tab along the extension thereof, wherein said at least one tab comprises a central portion and two side portions relative to said axis, opposite to said central portion, wherein said central portion has a radial thickness decreasing towards the side portions.
