Biotech Special (03:26)
DARPA gave Dr. Tom Oxley a million dollars to create an endovascular device that could control prosthetics with a patient's mind. Terence O'Brien, David Grayden, and Clive May discuss the different disciplines necessary to form an effective team.
Engineering Challenge (05:17)
Engineers needed to design the Stentrode as well as the catheter system to inject it into the bloodstream. Mark Tonga and other paralyzed individuals discuss their desire for independence. Current technology has shown improvements, but the electrodes do not last because the brain creates scar tissue; the Australian team describes how their catheter system avoids craniotomy surgery.
Promising Results (03:24)
The motor cortex coordinates movement. The Australian team created an animal study and found that the electrode embedded itself in the artery wall without causing a blockage or scar tissue. The human trial is scheduled to begin in 2017.
Putting the Pieces Together (02:33)
Dr. Oxley learns how to implant the devices at Mount Sinai Hospital. Dr. J. Macco explains that all the recent innovations show promise. Tonga wants to regain his independence and remains optimistic about the results.
Visualizing the Invisible (03:17)
Virtual reality now allows scientists, doctors, and patients see inside their bodies. Rob Parton creates slides depicting how cells become cancerous using microscopy. Dr. John McGhee brings them to life using 3D imaging techniques.
Creating Virtual Reality (04:21)
Dr. McGhee builds a three-dimensional model and explains how he has to create pathways from different components. Parton describes the innovative technology. Dr. Angus Johnston studies if nanoparticles can improve medicine delivery within a cell.
Exploring the Brain (04:44)
Medical experts educate stroke victims using virtual reality and their own imaging scans. After watching the technology, Victor Ashleford feels increased motivation to make appropriate lifestyle changes. Experts discuss the future of immersive technology applications.
