In this edition of our MedTech Spotlight Series, we spoke with Bill Hunter, President, CEO & CMO of Canary Medical, about how implantable sensors, connected devices, and AI are reshaping the future of healthcare. Best known for developing the world’s first smart knee with Zimmer Biomet, Canary Medical has focused on embedding intelligence directly into medical devices to generate real-world clinical insight.
Bill explained that Canary was founded on a belief that the future of MedTech wouldn’t be metal and plastic. Instead, most medical devices would need to collect data, be connected, and provide real-time clinical feedback to both clinicians and patients. That idea became the foundation of the company’s work.
“We were best known for making the world’s first smart knee with Zimmer Biomet, known as Persona IQ, and all of our programs shared the same premise: collecting data from inside medical hardware and relaying that to the world.”
On AI, Bill shared that it was central to Canary’s strategy. The goal was not only to diagnose complications, but to predict them before they happened.
More broadly, he believed AI’s greatest near-term value would be reducing clinician workload. While personalised care was the goal, we couldn’t all have our own personal clinician, so achieving that required collecting patient data and using AI to assist with diagnosis, treatment management, and patient monitoring.
However, Bill noted that adoption in healthcare remained mixed. Some clinicians and patients fully embraced data-driven care, while others remained cautious due to privacy concerns or reluctance to change established practices.
He saw this as a normal part of transformation in healthcare. Even recently, tools like ChatGPT had been seen as experimental, while AI-driven predictions around complications such as DVT or readmission were becoming increasingly accepted. Compared with past innovations like interventional cardiology, which had taken decades to gain adoption, AI was progressing at remarkable speed.
A key milestone for Canary had been turning implant-generated data into actionable insight. The company started by embedding sensors inside the knee but initially had no framework for interpreting the data. After years and tens of thousands of patients, they established benchmarks and were able to apply AI and large language models effectively.
“We could identify patients at risk for readmission, emergency department visits, deep vein thrombosis, or infection trends, using the data to anticipate rather than diagnose.” This led to meaningful clinical and economic impact, including reduced readmissions and significant per-patient savings.
Through its partnership with NanoHive Medical, Canary extended this platform into spine. By integrating its sensor array into intervertebral cages, the company was able to monitor recovery in real time while maintaining implant structure and stability.
This enabled continuous, objective assessment of fusion progression, mobility, and patient activity, moving recovery monitoring beyond periodic imaging and allowing for earlier intervention and more personalised care.
Bill’s path into MedTech, as he described it, was unplanned. A physician by training, he had always intended to remain in clinical practice. However, research he worked on during medical training eventually became drug-coated stents, which evolved into large-scale commercial technologies with Boston Scientific.
“What started as a side project suddenly involved hundreds and then thousands of employees and effectively ended my medical career.”
Reflecting on his career, Bill highlighted the importance of mentorship. In his late 20s, two board members played a formative role in his development, Glen Nelson, who brought medical and MedTech expertise, and Hank McKinnell, who provided deep business leadership. Their guidance shaped his approach to building and scaling companies, lessons he continued to rely on.
Outside of work, Bill remained a dedicated runner, having completed all six major marathons alongside many half marathons. Running was his way of resetting and reflecting. He also spent years coaching his sons in baseball, something that continued to connect them.
Across data, devices, and AI, Bill Hunter’s perspective reflected a clear shift in MedTech: from static devices to continuous intelligence. His work at Canary Medical demonstrated how connected implants and real-world data could move healthcare from reactive treatment to earlier, more informed intervention with the goal of improving outcomes at scale.
