A smart implant for amputees enhancing prosthetics comfort and integration

Introducing CBAS

Cambridge Bio-Augmentation Systems (CBAS) is developing a medical device that uses advanced bioengineering and monitoring technologies to act as the “USB connector” of prosthetics, to benefit healthcare providers and their patients.

The Challenge

The current stump and socket model for prosthetic attachment is generally uncomfortable for patients and non-scalable and inefficient for healthcare providers due to the unique nature of each socket.

The Solution

CBAS has developed an open standard to replace the painful stump left behind after a conventional amputation.

By capturing objective continuous patient data using integrated prosthetic  implants can alleviate some of the pressure on physiotherapists and physicians and can enhance the current care by producing unbiased and continuous information on the condition of the patient.

With remote patient monitoring systems, the processing unit can to objectively monitor and measure the activity of the user and the health of the amputation site. This system continuously transfers patient data to the healthcare provider and is a step towards providing remote and proactive diagnosis of the amputee’s condition


CBAS prosthetics has the potential to revolutionise the market. Vastly decreasing the cost of amputee care for charities and healthcare providers, allowing prostheses manufacturers to sell directly to amputees, and allow more amputees to afford and access high end bionics and prostheses.

  • Reduced prosthetics pain for users
  • Opens Neuroprosthics and high-end devices to this mass-market improving patients quality of life
  • Reduced cost of after care for healthcare providers and charities
  • More effective and personalised care for amputees

Five years from now...

In five years CBAS will be able to retrofit a high functionality prosthetic limb connector solution to any amputee that wants it. It will be the default standard of care for new amputees. CBAS will also have completed a number of collaborations with major device manufacturers, to bring a new generation of high-functionality, affordable limbs onto the market.

Industry Quotes:

“The most revolutionary prosthetic innovation for the mass market” 14 August 2015, Blouin Industry Review

“We think [CBAS connectors] are the future of prosthetics, as do many clued up amputees.” Joel Gibbarrd, Open Bionics

“It doesn’t matter how powerful your prosthetic ankle is, if your prosthetic socket is uncomfortable you will not use your leg” David Sengeh, MIT Media Labs

At Digital Catapult

CBAS is demonstrating the value of combining a patient monitoring system with the Prosthetic Interface Device(PID) the smart implant. The telemetry system is aimed to enable the measurement of improvements in patient quality of life and computing amputee-care risk factors. These measurements are specific to the care challenges and treatment objectives for major limb amputees and can reduce the need for regular clinic visits. They also allow outcomes-focused healthcare provision by delivering an objectively quantified measure of current health.

In the showcase these measures will be displayed live by a ‘clinician orientated’ dashboard, replicating the kind of information that would be therapeutically beneficial for a clinician to have on a patient.
