Definitions

  • U.S. Patent No. 2007032790 discloses a device treating stenosis with a main body and a sleeve.
  • the main body comprises one end, and the sleeve comprises the other end.
  • two wings in a closed state are disposed in the sleeve. After implant, the wings are expanded.
  • the invention provides a spinal dynamic stabilization device for decompression of narrowed spacing between adjacent vertebrae, foramen routes, for example, by increasing spacing of adjacent vertebrae.
  • Each vertebra includes a sagittal plane.
  • the spinal dynamic stabilization device includes at least a main body and a supporting member, and further includes a guiding and engaging mechanism for either open surgery or minimally invasive surgery procedures.
  • the device enters a closed state and packed in the tube delivery tools.
  • the closed device is guided and transported inside delivery tube, and then opened through designed mechanism once delivered at implant site.
  • the spinal dynamic stabilization device is consist of a foldable supporting structure that can be stretched and lean against the spine. Foldable supporting structure is closed at the same direction of main body such as clam structure.
  • the main body comprises a guiding groove.
  • the foldable supporting structure comprises support portions, wherein the support portions pivot in relation to each other.
  • the foldable supporting structure can also including , but not limiting to
  • the main body and the foldable supporting structure are metal or nonmetal material coated with a flexible material, and the flexible material comprises macromolecular compounds or a flexible metal.

Abstract

Dispositif (10) de stabilisation dynamique vertébrale destiné à soulager des douleurs dans le bas du dos par l'agrandissement du passage de foramen des patients atteints de sténose vertébrale. Chaque vertèbre comprend un processus épineux et des pédicules symétriques. Le dispositif (10) de stabilisation dynamique vertébrale comprend un corps principal (11), une structure pliable (12) de soutien et une barre coulissante (13). La structure de soutien comporte deux parties (121, 122) de soutien. Lorsque la barre coulissante s'approche du corps principal, les parties de soutien s'élargissent par rotation vers les vertèbres adjacentes de la colonne vertébrale.
