Abstract
An implant strip is disclosed. In some cases, the prosthesis can take the form of an implant strip that may be implanted through the use of a surgical procedure that minimizes incision sizes and may be considered less invasive than typical spinal implant procedures. The implant strip includes provisions for implantation, including teeth, spacing provisions, and various shapes.
Claims20
A method for implanting a spinal prosthesis comprising:
- making an incision in a patient;
- inserting the spinal prosthesis in an uncoiled state through the incision and into a space between adjacent vertebrae,
- wherein the spinal prosthesis comprises an implant strip and a separating strip,
- wherein the implant strip extends in a longitudinal direction,
- wherein the implant strip has a first lateral edge and a second lateral edge opposite to the first lateral edge,
- wherein the implant strip is made of a shape-memory material that coils the implant strip into a coiled state in the space between the adjacent vertebrae,
- wherein the implant strip includes a first surface between the first lateral edge and the second lateral edge, and a second surface opposite to the first surface and between the first lateral edge and the second lateral edge, and
- wherein the separating strip is disposed against the first surface of the implant strip;
- coiling the implant strip in the space between the adjacent vertebrae, wherein the separating strip covers less than an area of the first surface of the implant strip so as to provide gaps between coils of the first lateral edge of the implant strip when the implant strip is in the coiled state;
- and
- positioning the coils of the first lateral edge of the implant strip against a first vertebra of the adjacent vertebrae to facilitate bone growth into the gaps between the coils of the first lateral edge of the implant strip.

A method for implanting a spinal prosthesis comprising:
- making an incision in a patient;
- inserting the spinal prosthesis in an uncoiled state through the incision and between a first vertebra and a second vertebra,
- wherein the spinal prosthesis comprises an implant strip and a continuous separating portion,
- wherein the implant strip is elongated in a longitudinal direction and is made of a shape-memory material that biases the implant strip toward a coiled state,
- wherein the implant strip extends in a lateral direction from a first lateral side portion to a second lateral side portion,
- wherein the implant strip includes a first surface between the first lateral side portion and the second lateral side portion, and a second surface opposite to the first surface and between the first lateral side portion and the second lateral side portion, and
- wherein the separating portion is disposed at the first surface of the implant strip;
- coiling the implant strip between the first vertebra and the second vertebra, such that the implant strip forms a first inner coil and a second outer coil that coils around the first inner coil, the separating portion is disposed between the first inner coil and the second outer coil, and the separating portion covers less than an area of the first surface of the implant strip so as to provide gaps between the first inner coil and the second outer coil at the first lateral side portion of the implant strip;
- and
- positioning the spinal prosthesis between the first vertebra and the second vertebra so that the first lateral side portion of the implant strip engages the first vertebra to facilitate bone growth into the gaps at the first lateral side portion of the implant strip.

- inserting an implant strip in an uncoiled state through the incision and between adjacent vertebrae,
- wherein the implant strip is made of a shape-memory material that biases the implant strip to coil into a coiled state,
- wherein the implant strip extends in a longitudinal direction,
- wherein the implant strip has a first lateral edge and a second lateral edge opposite to the first lateral edge,
- wherein the first lateral edge of the implant strip forms an inclined surface across a width of the spinal prosthesis when the implant strip is in the coiled state,
- wherein the implant strip includes a first surface between the first lateral edge and the second lateral edge, and a second surface opposite to the first surface and between the first lateral edge and the second lateral edge,
- wherein the spinal prosthesis further comprises a separating portion disposed against the first surface of the implant strip, and
- wherein the separating portion covers less than an area of the first surface of the implant strip so as to provide gaps between coils of the first lateral edge of the implant strip when the implant strip is in the coiled state;
- coiling the implant strip between the adjacent vertebrae;
- and
- positioning the inclined surface of the coiled implant strip so as to fit a natural contour of a first vertebra of the adjacent vertebrae.
