Filed:

Jan 12, 2010

Appl. No.:

12/686134

Inventors:

Michael Harper - Pottstown PA, US

Assignee:

Globus Medical, Inc. - Audubon PA

International Classification:

A61B 17/70

US Classification:

606264, 606265, 606267, 606278

Abstract:

In a preferred embodiment, the present invention provides an offset connection assembly that can be used to securely connect a spinal implant to a bone anchor. In particular, the present invention preferably provides a variable angle connection assembly that is able to securely connect the spinal implant to the anchors even when there is a variance in the angle and position of the anchors with respect to the spinal implant. Furthermore, in a preferred embodiment, the present invention provides a connection assembly that will not inadvertently lock the components of the connection assembly preventing the relative movement of the components.

Appl. No.:

12/874002

Inventors:

Michael Harper - Pottstown PA, US

Assignee:

Globus Medical, Inc. - Audubon PA

International Classification:

A61B 17/70

US Classification:

606 86A

Abstract:

The invention encompasses instrumentation for rod reduction for use in orthopedic surgery that is ergonomic and intuitive to use. In certain embodiments, the invention encompasses a rod reducing instrument including a series of ratcheting mechanisms that reduces the need for large applications of manual force for rod positioning necessary during surgical procedures. The internalized mechanism also allows for a reduction in fine increments without an increase in surgical instrument profile or necessary force input. In certain embodiments, the instrument includes one or more channels to accept the locking delivery instrument further streamlining the surgical process. The rod reducing instrument of the invention refines the reduction process allowing for faster, stronger reduction, with a quick and effective release.

US Classification:

606278, 29428

Abstract:

In one embodiment, a medical device includes an elongate member, a first coupler, and a second coupler. The elongate member has a first end portion, a second end portion, and a side portion. The side portion of the elongate member has a first receiving portion and a second receiving portion. The first receiving portion is configured to receive a first support member. The second receiving portion is configured to receive a second support member. The first coupler is coupled to the elongate member and is configured to engage the first support member to help retain the first support member within the first receiving portion. The second coupler is coupled to the elongate member and is configured to engage the second support member to help retain the second support member within the second receiving portion.

Appl. No.:

13/281842

Inventors:

Michael Harper - Pottstown PA, US

International Classification:

A61B 17/84

US Classification:

606328

Abstract:

An orthopedic connection assembly is described that comprises a housing member for receiving an implant that is operably connected to a receiving member for receiving an anchor member. The connection assembly is configured to have a locking mechanism that secures and fixes the relative orientation between the implant and the anchor member. The connection assembly can comprise a plate member receivable within the housing member. When a securing member such as a set screw is introduced downwardly into the housing member to secure the implant, the securing member applies a lateral force to the plate member, which presses against an interference member within the receiving member. The interference member presses against the anchor member, such that the anchor member is fixed in a position relative to the implant.

International Classification:

A61B 17/88

US Classification:

606279

Abstract:

Systems, devices and methods related to spinal stabilization are provided. A system can comprise a plurality of cross-links. Each of the cross-links can include a central rod holder that extends substantially along a mid-line of the spine and a pair of extension members extending from the central rod holder. The extension members can be secured to a vertebral body via a fixation device, such as a spinal screw or a hook member having serrations and/or side-cuts. One or more rod members can be extended across the central rod holders of the cross-links, thereby forming a stable spinal stabilization system providing bilateral stress distribution across different levels of the spine.
