Embodiment Construction

[0043] Referring to the above figures, 4 is generally used to designate an expansion device adapted to provide a cavity in the vertebral body 8 .

[0044] The expansion device 4 is generally elongated and extends along an axis X of extension between a proximal end 8 and a distal end 10 .

[0045] In the following, the axial direction is used to indicate the direction parallel to the extension axis X, and the radial direction is used to indicate the direction perpendicular to the extension axis X and directed to the extension axis X.

[0046] The expansion device 4 includes a cylindrical shaft 12 extending from a proximal end 8 to a distal end 10 .

[0047] The handle 12 includes a first through hole 13 provided on one side of the proximal end 8 .

[0048] With respect to the axis X, there is provided a tube 14 integrated to the outside of the handle 12 and coaxial with the handle 12 so as to at least partially cover the handle 12 . The tube 14 extends between a first end 14&...

Abstract

An intravertebral widening device (4) extends from a proximal end (8) to a distal end (10) along an extension axis (X), said distal end (10) having an elastically deformable element (56) suitable to pass from a relaxed configuration for placing the distal end (10) within a vertebral body (6) to a deformed configuration for forming a cavity within said vertebral body (6). The elastically deformable element (56) comprises at least one tab (60) having, along the longitudinal extension thereof, a varying thickness relative to a radial direction incident with said extension axis (X) and contained in a perpendicular plane to said extension axis (X), such as to vary the stiffness of at least one tab (60) along the extension thereof.

Description

technical field [0001] The invention relates to an expansion device of the spinal cavity, especially an expansion device suitable for Kyphoplasty. [0002] The invention also relates to an injection device for kyphoplasty, which is suitable for injecting liquid cement into the vertebral body for repairing the vertebral body. [0003] The invention also relates to a kit of equipment for kyphoplasty and related methods of use. Background technique [0004] Expansion devices known for use in spinal lumens are inserted into the vertebral body in a relaxed configuration and then expanded to an expanded configuration to restore the shape of the vertebral body to create a suitable cavity within the vertebral body, followed by Inject into this cavity, for example, various glues, small pieces of bone, or bone fillers. [0005] Known expansion devices do not ensure controlled expansion within the vertebral body, ie they are not suitable for providing a three-dimensional cavity of co...
