Spinal disc annulus closure device

摘要

An implant (300) for repair of a spinal inter-vertebral disc, constituted of a first section and a second section, each having: a support member section (110); a proximal support member secured to the proximal end of the support member section and arranged to extend proximally thereof, the proximal support member (170) arranged in a deployed configuration to distend in the direction of the first face (130) of the support member section (110); and a pair of one inter-annulus support members (170), each of the pair of inter-annulus support members optionally exhibiting a plurality of stacked layers, arranged so as to cooperating under ejection forces to act as a single layer, the support member section of the first section secured to the support member section of the second section such that the second face of the first section faces the second face of the second section.

1. An implant for repair of a spinal inter-vertebral disc, the implant comprising:
a first section and a second section, each of said first section and said second section comprising:
a support member section exhibiting a longitudinal axis, said support member section having a first face and a second face opposing said first face, said support member further having a distal end and a proximal end;a proximal securing member secured to said proximal end of said support member section and arranged to extend proximally thereof, said proximal securing member arranged in a deployed configuration to distend in the direction of said first face of said support member section; anda pair of inter-annulus support members, each of said pair of inter-annulus support members arranged on opposing sides of said longitudinal axis of said support member section along said proximal end, each of said pair of inter-annulus support members exhibiting a first end secured to the proximal end of said support member section, a second end and a link member coupling said first end to said second end,wherein each of said inter-annulus support members has a deployed configuration wherein the second end of each of said inter-annulus support members extends away from the longitudinal axis of said axial support member section, a first face of each of said inter-annulus support members generally facing said support member section and generally concavingly curved when viewed from the proximal end of said support member section, and a second face of each of said inter-annulus support members generally convexingly curved when viewed from the proximal end of said support member section, and wherein said support member section of said first section secured to said support member section of said second section such that the second face of said first section faces the second face of said second section.
