Abstract
An implantable article for use with an anchor and a non-metal rod assembly includes a ring having a body including an outer surface, an inner surface defining an aperture extending through the body configured to engage a non-metal rod. The ring body further includes protrusions extending from the inner surface into the aperture, wherein the protrusions are spaced apart from each other axially and circumferentially along the inner surface.
Claims25
An implantable article for use with an anchor and a non-metal rod assembly comprising:
- a ring having a body including an outer surface, an inner surface defining an aperture extending through the body configured to engage a non-metal rod, and protrusions extending from the inner surface into the aperture, wherein the protrusions are spaced apart from each other axially and circumferentially along the inner surface.
An implantable article for use with an anchor and non-metal rod assembly comprising:
- a ring having a body including an outer surface and an inner surface defining an aperture extending through the body configured to engage a non-metal rod, wherein a first channel extends axially into the body from a first end, and a second channel circumferentially displaced from the first channel along the body extends axially into the body from a second end different than the first end.
An implantable article for use with an anchor and a non-metal rod assembly comprising:
- a ring having a body including an outer surface, an inner surface defining an aperture extending through the body configured to engage a non-metal rod, and a first protrusion extending circumferentially around a portion of a circumference of the inner surface of the body.
An implantable article for use with an anchor and non-metal rod assembly comprising:
- a clamp having an opening and configured to engage an anchor;
- a ring configured to fit within the opening of the clamp having a body including an outer surface and an inner surface defining an aperture extending through the body configured to engage a non-metal rod, wherein the body comprises a Modulus of Elasticity (MOE) and the non-metal rod comprises a MOE and the difference between the MOE of the non-metal rod and the MOE of the body is not greater than about 100 GPa.
An implantable article for use with an anchor and non-metal rod assembly comprising:
- a ring having a body including an outer surface and an inner surface defining an aperture extending through the body configured to engage the non-metal rod, wherein the body comprises a first portion comprising a first material and a second portion comprising a second material different than the first material.
