International Classification:

A61B 17/70
A61B 17/58

US Classification:

606264, 606 60

Abstract:

The present invention relates to a clamp, and, more particularly, to a clamp for securing the position of a bone anchor with respect to a longitudinal rod, preferably for use in the spine. The clamp may include a housing, a rod clamping assembly, and a bone anchor clamping assembly. The clamp preferably enables the longitudinal axis of the rod to be offset or laterally displaced from the longitudinal axis of the bone anchor. The rod clamping assembly and the bone anchor clamping assembly are preferably moveably coupled to the housing in order to provide increased flexibility to better accommodate the location and geometry of the longitudinal rod and to better accommodate bone positioning.

International Classification:

A61B 17/70

US Classification:

606264

Abstract:

The present invention relates to an outrigger for securing a longitudinal spinal rod, preferably a horizontally offset spinal rod, with respect to a bone anchor. The outrigger may include a housing having a first throughbore to receive the bone anchor and a second throughbore to receive the spinal rod, a cam for surrounding the bone anchor, the cam being disposed within the first throughbore, and a collet having a passage for surrounding the spinal rod, the collet being disposed within the second throughbore. The cam may be moveable from a first position to a second position such that, in the first position, the spinal rod and bone anchor are free to move with respect to the housing and in the second position, the spinal rod and collet are secured with respect to the housing. The collet may be moveable between a first configuration to a second configuration such that movement of the cam from the first position to the second position causes the collet to move from the first configuration to the second configuration. The cam preferably may move into contact with the collet when the cam is moved into the second position. The collet preferably may be compressible into the second configuration. The cam may also include an intermediate position wherein in the intermediate position, the spinal rod is free to translate with respect to the housing but is prevented from articulating with respect thereto.

International Classification:

A61B 17/70

US Classification:

606249

Abstract:

An interspinous spacer assembly () for insertion and/or implantation between spinous processes of adjacent superior and inferior vertebrae includes an interspinous spacer member () sized and configured for insertion into the interspinous space located between adjacent spinous processes and an engagement mechanism () for operatively coupling the spacer member to the adjacent spinous processes and for preventing migration of the assembly once implanted. The interspinous spacer assembly is adjustable to conform to the individual anatomy of a patient's spine.

International Classification:

A61B 17/70
A61B 17/88

US Classification:

606249, 606279

Abstract:

An allograft interspinous spacer for implantation into an interspinous space located between spinous process of adjacent vertebrae. The spacer preferably includes a body, a core and a plurality of deployable retainers. The body may be operatively associated with the plurality of deployable retainers. In use, after the body has been inserted into the interspinous space, the plurality of retainers is deployed so that they prevent migration of the spacer. The core is preferably sized and configured to be inserted and/or moved into operatively engagement with the body to deploy the plurality of retainers.
