Abstract
The subject disclosure is directed to systems, apparatuses, devices and methods for vertebral and spinal correction. In some embodiments, an expandable implant is provided which may be inserted inside the vertebral body and/or between two vertebrae, for instance, for maintenance and/or restoration of a space therein or there between. In certain embodiments, the implant includes a mechanical resistance that prevents the expandable implant from contracting once it has been expanded. Methods of treatment and methods of use of such implants for the alleviation of back pain (for example) are also provided herein.
Claims40
A vertebral expandable implant, comprising:
- first and second bearing surfaces intended to evenly move away from one another according to a plane of expansion during expansion of the implant;
- at least first and second opposed ends of the implant associated with each of the bearing surfaces;
- and
- a retaining element for retaining the implant in an expanded configuration,
- at least one support extending linearly between one of the at least first and second opposed ends of the implant and an underneath side of one of the first and second bearing surfaces, wherein:
- the retaining element comprises a deformable portion, a first end associated with the first end of the implant and a second end associated with the second end of the implant,
- a first engagement element provided proximate the second end of the retaining element for engagement with a second engagement element provided on the second end of the implant, and
- engagement between the first and second engagement element and deformation of the deformable portion of the retaining element substantially prevents the second end of the implant from moving away from the first end of the implant.

An expandable implant, comprising:
- a first and second bearing surfaces, wherein the first and second surfaces are intended to evenly move away from one another according to plane of expansion during expansion of the implant;
- at least first and second opposed end members associated with each of the bearing surfaces;
- a retaining element;
- and
- at least a pair of supports associated with at least one of the bearing surfaces, at least one of the bearing surfaces additionally associated with at least one of the end members, wherein
- a first support of the pair including a first engagement element, said first support extending linearly between one of the at least first and second end members and an underneath side of one of the first and second bearing surfaces upon expansion of the implant,
- a second support of the pair including a second engagement element, said second support extending linearly between the one of the at least first and second end members and the underneath side of the one of the first and second bearing surfaces upon expansion of the implant, and
- upon expanding the implant a predetermined amount, at least a portion of the first engagement element engages with at least a portion of the second engagement element to prevent movement.
5 more elements
A method for restoring a space between two surfaces, comprising the steps of:
- inserting an expandable implant, wherein the expandable implant includes a contracted and an expanded configuration, and the implant comprises:
- a first and second opposed plates each including a recess configured for engaging a portion of a respective vertebrae of two vertebrae adjacent each respective plate, wherein the first and second plates are intended to move away from one another according to a plane of expansion as the implant is expanded;
- at least first and second opposed end members associated with each of the opposed plates, wherein at least one of the end members includes an aperture configured for receiving one end of a retaining element;
- a retaining element;
- and
- at least a pair of first and second supports associated with at least one of the first and second plates and additionally associated with at least one of the first and second end members, wherein at least one of the pair of the first and second supports comprises a first engagement element and a second engagement element for engagement with the first engagement element;
- aligning the recesses with respective vertebral bones such that when the implant is expanded the recesses engage a portion of the vertebral bones;
- and
- expanding the implant from the contracted configuration to the expanded configuration and thereby restoring the space.
6 more elements
An expandable implant, comprising:
- a first and second bearing surfaces, wherein:
- the first and the second bearing surfaces remain substantially parallel to each other during expansion of the implant, and
- the first and second surfaces are intended to evenly move away from one another according to plane of expansion during expansion of the implant;
- at least first and second opposed end members associated with each of the bearing surfaces;
- a retaining element;
- and
- at least a pair of supports associated with at least one of the bearing surfaces, at least one of the bearing surfaces additionally associated with at least one of the end members, wherein
- a first support of the pair including a first engagement element,
- a second support of the pair including a second engagement element, and
- upon expanding the implant a predetermined amount, at least a portion of the first engagement element engages with at least a portion of the second engagement element to prevent movement.
