Overview

Oxford Heartbeat Ltd. is a United Kingdom medical software company based in London. It develops decision-support software for clinicians, with its flagship product being PreSize® Neurovascular. According to the company's official website, PreSize® Neurovascular is a decision-support medical software tool that helps clinicians plan and perform neurovascular surgeries involving implant devices in real time. The software allows users to import routine patient scans, automatically build a virtual patient-specific blood vessel model, position digital twins of different implants into that model, and generate a best-fit device recommendation based on the patient's specific anatomy. Clinicians can then make further adjustments and rehearse different surgical scenarios before the actual procedure. The company positions its technology around improving surgical decision-making and patient outcomes. Its stated mission is to provide clinicians with powerful technology to make life-saving decisions and offer every patient the highest standards of care. Its stated vision is a world where successful surgery is the norm rather than the exception. The official website highlights several performance claims, including 96% highest validated accuracy in device deployment simulation, a three-minute real-time case rehearsal time on PreSize®, and selection of devices 4 mm shorter using PreSize® compared with procedures without it. It also notes that 10 UK hospitals are participating in the PreSize® Neurovascular clinical impact trial, with more expected to join. Oxford Heartbeat operates in the medical technology and surgical planning software space, specifically focused on neurovascular interventions. Its product is intended to support clinicians in selecting the best-fit implant device before surgery, aiming to reduce surgical complications and improve patient outcomes.
