Meet Avior

The Avior MPK helps you to do more of the things you love

“Avior is really easy to use. It allows me to get on with the things I love, like having friends around for dinner, or getting out into the garden for a stroll and a chat.”

- Denise

Life isn’t one-size-fits-all, and neither is Avior - go beyond preset modes

Each patient is unique, which is why Avior allows you to tailor and fine-tune key features and settings to individual needs and clinical requirements, supporting wearers and ensuring confidence at every step of the journey.

Easy to set up with three base configurations

Quick and intuitive to set up, simply download our new SMARTSTEP® app, which guides you step-by-step through the programming sequence. In just 10 minutes, Avior is ready to go! Select the base configuration that best suits your wearer. These include: Lock-Lock, Lock-Free, Yield-Free.

Fine tune and customise key features and settings

Once the device is programmed, additional features can be fine-tuned to deliver optimal levels of resistance, maximising comfort, safety, and confidence for every wearer. These include: Stance Flexion, Swing Extension Control, Standing Support, Dynamic Slope & Stairs Descent, Supported Standing & Sitting.

Connecting prosthetists and physios for better outcomes

Our new SMARTSTEP® app will soon be accessible to Physios. Allowing them to adjust the device’s base configurations during physio sessions, supporting wearers in a safe environment as their mobility changes. Physios will also be able to video record activity sessions with wearers, which get logged against the device record so prosthetists can review at their convenience, or during the next prosthetic appointment.

Aids rehabilitation in between clinic sessions

Avior, powered by our SMARTSTEP® technology, enables remote monitoring of device usage statistics, including walking, sitting, and standing. This provides valuable insights into a wearer’s functional abilities and progress over time. For remote support or troubleshooting, wearers can securely record and share videos, data and any issues they encounter in their own environment via the SMARTSTEP® app, ensuring seamless communication with their prosthetist.^

Easily adaptable to the wearer's needs

Avior can be adapted to suit a range of functional abilities, whether the wearer starts out in a wheelchair or is a more confident ambulator. As the wearer’s confidence evolves, settings on Avior can be adjusted up or down at any time providing a truly flexible device.

Designed for today, ready for tomorrow

Thanks to the innovative SMARTSTEP® technology built into Avior, firmware updates can be made Over the Air (OTA). This allows clinicians to access updates directly in the clinic without returning the device to the manufacturer. As Blatchford releases new features and functions, clinicians can immediately access them using the OTA functionality.†

Features & Design

Key Features of Avior

Polycentric Design

Our Avior MPK uses a biomimetic design, that mimics the natural movement of a human knee, combining both rolling and sliding motions. As the knee flexes, Avior's chassis moves backward similar to how the femur bone moves relative to the tibia in a real knee joint. This results in the socket being pressed into the wearer which helps maintain contact & control but also ensures the knees are symmetrical when seated.

Waterproof - Rated IP65

With an IP65 waterproof rating, Avior ensures that exposure to water won't disrupt your patient's day. They can confidently engage in water-based activities such as fishing, boating, or paddling without concern. Whether it's water splashes, accidental spills, light drizzle, or heavy showers, Avior provides complete peace of mind for your patients.

48hrs Battery Life

Stay powered for longer with up to 48 hours battery life, ensuring reliable performance. The convenient battery status indicator keeps wearers informed, and with a quick 4-6 hour recharge time, meaning they're always ready to go. Plus, the ON/OFF switch lets them preserve battery life when not in use, perfect for times when they forget their charger.

Magnetic USB-A Charging

Avior charges using a magnetic USB-A charger, a common charging connection found in most homes, cars and other places, meaning wearers can easily charge their device on the go. The magnetic charging connection means it is easy for wearers to know when the charger has ‘snapped’ into place to charge.

3 x Base Configurations

Programmed with a choice of three base configurations, Avior is designed to support wearers at every stage of their journey and adapt with them, building confidence as they progress. Each configuration allows for key feature customisation, ensuring an optimal and natural user experience.

How does the user switch between Avior configurations? 

The user does not switch between configurations. Avior MPK configuration set up is programmed by the clinician.
Does IP65 cover salt & chlorinated water? 

No. Fresh water only.
Does Avior have more sensors than Orion3? 

Yes.
In addition to heel load, what else does the knee look for to release to sit? 

Posterior inclination and deceleration of posterior angular velocity.
Which countries have reimbursement for K2 MPK use? 

The United States is the largest country offering reimbursement for K2 MPK products. Germany also reimburses for this patient category.
Is a long-term rental scheme available?

Yes, rental units are available. Please contact your sales representative to discuss options.
Does Avior have a hybrid cylinder, like ORION3? How is Avior different?
Avior utilises a hydraulic cylinder. This design is ideal to accommodate the features and walking speeds required from the intended patient group.

The main differences are:

Orion 3 & Linx
- Hybrid pneumatic/hydraulic cylinder to control swing phase.
- 5 swing speeds controlled by pneumatic portion of the cylinder.
- Hydraulic aspect only controls swing flexion with minimal effect on extension.
Avior’s hydraulic cylinder assists and controls the swing phase
- The cylinder has a spring energised accumulator that provides extension assist.
- The hydraulic cylinder controls both flexion and extension resistances allowing control of swing extension speed.
With physio, how long does it take a user to learn the features of Avior? 

This will depend on the Physio; we have supporting materials and training guides to help them.
