US Patent:

8016831, Sep 13, 2011
Filed:

Feb 8, 2007
Appl. No.:

11/703976
Inventors:

Carlos E. Gil - Collierville TN, US
Rick C. Sasso - Carmel IN, US
Mark C. Dace - Collierville TN, US
Assignee:

Warsaw Orthopedic, Inc. - Warsaw IN
International Classification:

A61F 5/00
A61B 17/90
A61B 19/00
US Classification:

606 86A
Abstract:

Systems and methods of shaping surfaces of vertebral bodies include a reference guide instrument that can be positioned relative to a disc space between vertebral bodies and referenced to the caudally located endplate of the disc space. The reference guide instrument can then be employed to guide preparation instruments to the vertebral bodies in an orientation and spacing referenced to the caudal endplate of the subject disc space to shape vertebral surfaces to receive an implant.

US Patent:

8070815, Dec 6, 2011
Filed:

Aug 6, 2008
Appl. No.:

12/187125
Inventors:

Kidong Yu - Memphis TN, US
Mark Dace - Collierville TN, US
Assignee:

Warsaw Orthopedic, Inc. - Warsaw IN
International Classification:

A61F 2/44
US Classification:

623 1714, 623 1711
Abstract:

An intervertebral implant system for positioning between an upper vertebra and a lower vertebra is provided. The implant system comprises an intervertebral implant and a staple. The implant comprises an inferior plate and a superior plate, while the superior plate has a vertebral surface facing the upper vertebra and the inferior plate has a vertebral surface facing the lower vertebra. There are two grooves on at least one vertebral surface extending at an angle outward from a centerline on the vertebral surface as they extend from the anterior portion of the plate toward the posterior portion of the plate. When in use, the staple is associated with the two grooves for maintaining stability of the intervertebral implant and preventing backing out of the intervertebral implant. The staple also has two arms and has a generally rectangular shape prior to use.

US Patent:

8083798, Dec 27, 2011
Filed:

Apr 4, 2005
Appl. No.:

11/098167
Inventors:

Randall N. Allard - Germantown TN, US
Robert B. Rice - Southaven MS, US
Mark C. Dace - Collierville TN, US
Assignee:

Warsaw Orthopedic, Inc. - Warsaw IN
International Classification:

A61F 2/44
US Classification:

623 1716, 623 1714, 606 90
Abstract:

A spacer for inserting between vertebral members. The spacer has a non-spherical shape with an anterior section having a first shape and a posterior section having a different shape. An attachment means is positioned within the posterior section, and may include a receiver for attachment with an insertion device, and an anti-rotation mechanism for assistance in removing the spacer from the insertion device. Embodiments of using the spacer is also disclosed which may include inserting the spacer between the vertebral members in a generally posterior approach. Once inserted, the insertion device acts with the anti-rotation device to remove a connection mechanism from the receiver. The spacer remains between the vertebral members and provides relief to the patient.

Transverse Centering Tool With Pin Placement Guides

US Patent:

8142440, Mar 27, 2012
Filed:

Nov 14, 2008
Appl. No.:

12/271357
Inventors:

Mark C. Dace - Collierville TN, US
Richard G. Fessler - Winnetka IL, US
Assignee:

Warsaw Orthopedic, Inc. - Warsaw IN
International Classification:

A61B 17/60
A61B 17/90
US Classification:

606 96
Abstract:

A centering tool for transverse centering between an upper vertebra and a lower vertebra is disclosed. The centering tool comprises a support portion having a proximal end and a distal end, two handles, and two pin placement guides, each guide having a hollow cylinder shape for the placement of a drill or pin on each of the upper and lower vertebrae. The two handles each have a proximal end and a distal end, wherein the proximal end of each handle is connected to the proximal end of the support portion, and the distal end of each handle ultimately contact the uncular joint of one of the vertebrae when centering is achieved. Preferably, each handle has a spring that biases the handle in a closed position so that the distal portions of both handles abut each other in a resting or closed position.

Percutaneous Spinous Process Fusion Plate Assembly And Method

US Patent:

8562650, Oct 22, 2013
Filed:

Mar 1, 2011
Appl. No.:

13/037729
Inventors:

Mark C. Dace - Collierville TN, US
Assignee:

Warsaw Orthopedic, Inc. - Warsaw IN
International Classification:

A61B 17/70
US Classification:

606248
Abstract:

A spinal implant helps stabilize vertebrae for fusion. The implant is particularly adapted for percutaneous implantation, but may also be used with other access techniques. The implant includes first and second plates that extend through a slot in a frame. When installed, the frame extends laterally through the interspinous space, and the plates extend superiorly-inferiorly along respective lateral sides of the spinous processes. The plates are moved toward one another and relative to the slot to clamp the implant to the spinous processes. The slot may be variably sized along its length, and the plates may move into differently sized portions of the slot during the clamping process.

Helical Lead For A Drive Shaft Collet

US Patent:

7992878, Aug 9, 2011
Filed:

Jul 31, 2006
Appl. No.:

11/496651
Inventors:

Mark C. Dace - Collierville TN, US
Assignee:

Warsaw Orthopedic, Inc - Warsaw IN
International Classification:

B23B 31/117
US Classification:

279102, 279 93, 606 80, 606108
Abstract:

Embodiments of a drive shaft collet adapted for linking a surgical drive shaft to a surgical instrument so that the instrument may be driven by the drive shaft are disclosed. The collet includes a helically-swept cutout which forces a received shaft to be rotated into alignment during insertion. Collectively, the drive shaft collet and shaft are designed to avoid the need for multiple attempts at inserting the shaft into the collet in order to align the flats on the shaft with the flats on the collet.

Devices And Methods For Spacing Of Vertebral Members Over Multiple Levels

US Patent:

20070173855, Jul 26, 2007
Filed:

Jan 17, 2006
Appl. No.:

11/333720
Inventors:

Brad Winn - Southaven MS, US
Craig Squires - Cordova TN, US
Mark Dace - Collierville TN, US
Bret Wilfong - Southaven MS, US
Jared Shoup - Memphis TN, US
International Classification:

A61B 17/58
US Classification:

606090000
Abstract:

The present application is directed to devices and methods to space apart vertebral members over two or more spinal levels. Embodiments of the devices may include a power source, supply line, and adjustable members. The adjustable members may be positioned along two or more spinal levels. The supply line may extend between each of the members and the power source. Activation of the power source may feed power through the supply line and to each of the adjustable members. Members may move from a closed orientation towards an open orientation to space the vertebral members.
