Disruptive Robotics

Catherine Mohr and her da Vinci Surgical System.
On February 1st of this year, Catherine Mohr, Director of Medical Research and chief spokesperson for Intuitive Surgical (ISRG:NASDAQ), gave a talk on the campus of CMU. (Video of talk and Q&A).

I watched the video wherein Mohr pointed out that most of the new robotic-assisted surgical procedures - including those provided by her company's da Vinci Surgical System, are simply improved versions of surgeries that have long been done through open or laparoscopic access -- and that's not disruptive. She felt that new technologies are poised to profoundly disrupt the field of surgery... new methods to enable the body's own immune system to fight off problems, or new systems to enable doctors to implant medicines in just the right spot to fight a disease without corrupting other nearby organs.

Aeon Scientific's magnetic catheter steering system.
Last week I had the good fortune to visit the Institute of Robotics and Intelligent Systems (IRIS) Labs at the Swiss Federal Institute of Technology (ETH) in Zurich, Switzerland. I saw some products in their final stages of development which fit the disruptive aspect of what Mohr was talking about. The ETH IRIS lab, headed by Professor Bradley Nelson, and his team of 40 researchers, Masters and PhD students, and postdocs, amongst it's many projects, is in the process of spinning-off a medical device company developing a new type of robotic catheter steering system using patented technology for electromagnetic manipulation.

Nelson, who heads the team at the lab, is also a founder and member of the Board of Directors of Aeon Scientific. Aeon's magnetic catheter steering system is initially set up to support electrophysiologists during catheter ablation procedures for the treatment of arrhythmias, such as atrial fibrillation. It allows them to move the ablation catheter within the heart of the patient with magnetic fields. The improved control leads to better outcomes and reduced treatment costs.

Aeon's new technology is a platform with the potential for other medical applications such as gastroenterology, neurosurgery, ophthalmics, and targeted drug delivery. I saw an example of the targeted drug delivery as it related to ophthalmics - moving a micron-sized object placed into the retina of an eye. The steering system - the magnetic coils and lens system on the left (a miniature of the fully-sculpted one shown in the human-sized cardiac system shown above), and a computer station for the doctor to steer the little micron-sized rectangle you can see in the center of the photo on the right, to the exact right spot for it to deliver it's therapeutic medicine, comprise the medicine delivery system.

This is exactly what Catherine Mohr was talking about: delivering medicine to the exact right spot so that it can safely do it's job.
