Abstract:

An intervertebral disc prosthesis comprises a first prosthesis component, a second prosthesis component, and an intermediate prosthesis component positioned between the first prosthesis component and the second prosthesis component. The first prosthesis component and second prosthesis component are configured to rotate upon the intermediate prosthesis component. The first prosthesis component includes a vertebra facing surface with a central channel formed in the vertebra facing surface. The central channel is designed and dimensioned to engage an insertion arm of a disc insertion tool. The first prosthesis component also includes at least one indentation configured to engage at least one retention arm of the disc insertion tool. The at least one indentation of the first prosthesis component may comprises at least one groove formed in a collar of the first prosthesis component. In one embodiment, the first and second prosthesis components are plates and the intermediate prosthesis component is a core.

International Classification:

A61F 2/44
A61F 2/28

US Classification:

623017140, 623023510

Abstract:

An intervertebral disc prosthesis comprises a superior endplate and an inferior endplate. The superior and inferior endplates include vertebra fixation surfaces designed to engage vertebral bodies. A composite material is provided on the vertebra fixation surfaces. The composite material includes an osteoconductive component and an osteoinductive component. The osteoconductive component provides a porous matrix or base that facilitates bone growth. The osteoinductive component provides a stimulant material that encourages growth of the bone cells between the osteoconductive component of the endplate and the vertebral body facing the endplate. In one embodiment, the osteoconductive component is permeated by an osteoinductive material to provide the composite material. In another embodiment, the composite material includes a non-resorbable portion that includes osteoconductive substances and a resorbable portion that is doped with osteoinductive substances.

International Classification:

A61B 17/58

US Classification:

606 90

Abstract:

An intervertebral distraction instrument comprises a first vertebra engaging member and a second vertebra engaging member. The first vertebra engaging member includes a vertebra anchor member configured to prevent lateral movement of the distraction instrument while allowing anterior-posterior movement of the distraction instrument during engagement with the first vertebrae. A similar anchor member may also be provided on the second vertebra engaging member. The anchor member of the distraction instrument may be provided on the end portion of an elongated arm of the distraction instrument. In one embodiment, the anchor member of the distraction instrument comprises a keel that includes edge configured to cut into the vertebra. In another embodiment, the anchor member of the distraction instrument comprises a spike.

Abstract:

Various systems and methods are provided for surgical and interventional planning, support, post-operative follow-up, and functional recovery tracking. In general, a patient can be tracked throughout medical treatment including through initial onset of symptoms, diagnosis, non-surgical treatment, surgical treatment, and recovery from the surgical treatment. In one embodiment, a patient and one or more medical professionals involved with treating the patient can electronically access a comprehensive treatment planning, support, and review system. The system can provide recommendations regarding diagnosis, non-surgical treatment, surgical treatment, and recovery from the surgical treatment based on data gathered from the patient and the medical professional(s). The system can manage the tracking of multiple patients, thereby allowing for data comparison between similar aspects of medical treatments and for learning over time through continual data gathering, analysis, and assimilation to decision-making algorithms.

International Classification:

A61B 17/16

Abstract:

A system includes an ultrasonic instrument and a bone insertion element. The instrument includes an ultrasonic transducer and an ultrasonic blade. The ultrasonic transducer is operable to convert electrical power into ultrasonic vibrations. The ultrasonic blade is in acoustic communication with the ultrasonic transducer such that the ultrasonic transducer drives the ultrasonic blade to vibrate ultrasonically to form an opening within bone. The bone insertion element is configured to be inserted within the opening formed by the ultrasonic blade.
