Presenting Mimesis - C

The next generation of cervical disc arthroplasty

Mimesis -C duplicates the features of a natural cervical disc

Meliora Medical are manufacturers of the innovative Mimesis -C. It will provide a life-changing surgical relief for those living with Degenerative Disc Disease (DDD) that causes neck, shoulder and arm pain.

Despite its name, DDD is not a disease. Rather, it is a part of the natural aging of the spine and is caused when a disc in the spine begins to lose its ability to rehydrate. The Mimesis-C is modelled on the natural functions, features and abilities of a human cervical disc making it a ‘biomimetic concept’, an idea inspired by and modelled on animals, plants and biological processes.

Despite the concept being well-established, it has only been recently that the idea of modelling design and production on nature’s processes has been termed ‘Biomimicry’. Today, Biomimicry has been applied to diverse fields, such as agriculture, transport, communication and medicine – bringing us the revolutionary Mimesis-C.

Benefits

Dynamic post-surgical ultrasound visualisation

The post-surgical ultrasound can be done in clinic allowing the surgeon to see functional images of the Mimesis-C while the patient goes through their full range of movement.

The procedure is able to take place seamlessly in a spine clinic – avoiding extra hospital appointments and the radiation exposure involved with CT and MRI scans.

Mimics the natural rhythm of hydration of a natural disc

The hydrogel core of the Mimesis-C mimics the way a natural cervical spine disc absorbs and releases fluid over a 24-hour period.

During the night the disc absorbs fluid, rehydrating and re-pressurising the disc, and loses fluid during the day when it must carry higher loads. The hydrogel enables the Mimesis-C to work alongside the natural spine to achieve harmonious motion.

Unconstrained Range of Motion

The Mimesis-C provides complete motion freedom complementing the natural disc to enable the person to move comfortably in all directions.

The motion features of the Mimesis-C take into account the fact that no movement of one disc in the spinal column is independent of another. The artificial disc flawlessly supplements the motion range of other natural discs.

Shock Absorption

Mimesis-C has unrivalled shock absorption properties.

Naturally, the spines ‘S’ shape and cushioned invertebral discs absorb tremors caused by impacts. The combination of these high-pressure cushions and the tension band in the back makes movement possible.

The Mimesis-C impeccably replicates the natural shock absorption capabilities of the natural spine, whilst stopping excessive motion.

Adaptive Centre of Rotation

The Mimesis-C was designed with an adaptive centre of rotation. A centre of rotation is a point around which all other points in a body move.

When a cervical disc degenerates the differences between the centre of rotation at different spinal levels is amplified. So an artificial cervical disc must have an adaptive centre of rotation to match the individual patients’ unique physiological profile.

Biometric Behaviour

The natural spine differs from the singular large joints that early artificial discs were modelled on; it is a complex set of joints that all work together to enable safe controlled movement.

By copying the different complex elements of the natural cervical spine through Mimesis-C biomimetic design, we can finally provide patients with an artificial disc that realistically acts like a natural spinal disc.

How does it work?

Hydrogel Core

Represents the inner core of the vertebral disc made up of a jelly-like substance that mainly comprises of water.

Polymer Jacket

Represents the tough exterior which surrounds the soft inner core of the vertebral disc. It also connects the vertebrae above and below the spinal disc and provides much-needed resistance to rotation and shear forces.

Primary Fixation

The outer ring duplicates the natural fixation to the vertebra as a vertebral disc. It also allows the natural swelling of the hydrogel core.
