Inventors:

- AUDUBON PA, US
Ross Morris - Norristown PA, US
Daniel Spangler - Green Lane PA, US

International Classification:

A61B 17/70

Abstract:

Connector assemblies, systems, and methods thereof. An articulating connector has a first end that clamps to a first rod in an existing construct and a second end having a second end that clamps to a second rod in a new construct or such that the new construct can be extended from the existing construct. In the case of different sized constructs used in different areas of the spine, an articulating connector has a first end that clamps to a first rod in a new construct having rods of a first size and a second end having a second end that clamps to a second rod in a new construct having rods of a second size. The clamping portions are capable of translating and rotating with respect to each other.

International Classification:

A61B 17/70

Abstract:

Disclosed are laminoplasty devices and systems, kits that include such laminoplasty devices or systems or components thereof; and methods of assembling and using such laminoplasty devices and systems. In particular, articulating laminoplasty devices are provided that allow lamina plates to be adjusted angularly and transitionally with respect to a cage connecting the lamina plates. Also provided are laminoplasty plates that are configured so as to be assembled with a bone graft housing, and which provide an opening configured to facilitate bone graft insertion into the housing. Further provided are expandable laminoplasty fixation systems that include a lateral mass plate, a lamina plate and a set screw that when screwed and unscrewed, allows one to contract and expand the plates with respect to one another.

International Classification:

A61B 17/70
A61B 17/88

Abstract:

A cervical plate assembly is disclosed. The cervical plate assembly includes a base plate including: (1) at least two bone screw seats, each bone screw seat including a borehole dimensioned to receive a bone screw, and (2) a first blocking seat positioned between the at least two bone screw seats. The cervical plate assembly includes a blocking mechanism retained within the first blocking seat of the base plate. The blocking mechanism is selectively positionable between a closed position in which the blocking mechanism obstructs at least one bone screw seat to retain a bone screw with the base plate, and an open position in which the bone screw seats are unobstructed.

International Classification:

A61B 17/70

Abstract:

The present application discloses transverse connectors that are connectable to first and second rod members that extend along a length of the spine. The transverse connectors are capable of gripping first and second rod members that are at different distances relative to one another, as well as at non-parallel angles relative to one another. In some instances, the first and second rod members can be bottom-loaded into the transverse connectors, while in other instances, the first and second rod members can be side-loaded into the transverse connectors.
