Join the team that makes a difference

If you are a driven individual who would like to join a team of innovators changing the future of surgery, we would love to hear from you.

The appeal about PreSize® is that simulation of implants will play a critical role in future clinical care and trials. Study results demonstrate there is a high degree of validation and reliability in how PreSize® predicts the implant.

Prof. Ansaar Rai
Chairman of Department of Neuroradiology at West Virginia University, USA

It’s great to see an AI solution tailored to decrease pre-operative stress and improve care - I’m looking forward to participating in the prospective study that will see the use of PreSize® software in our practice and evaluate its impact.

Oxford Heartbeat has demonstrated openness and engagement with the INR community and wants to engage in medical research, which you can see from their prospective UK multicentre study.

Dr. Jonathan Downer
Consultant Interventional Neuroradiologist at Department of Clinical Neurosciences Edinburgh, UK

Oxford Heartbeat clearly articulated a unique, commercially viable approach to an unmet health need. Crucially, it was also apparent that the company had strong visionary leadership and a diverse team with the skills and expertise to deliver a successful project.
