First Wireless Pacemaker Fits Inside The Heart

Unlike a traditional pacemaker, which requires surgical insertion and involves hooking up lead wires, the Nanostim device is installed via a catheter and attaches directly to the heart muscle.

What's the Latest Development?


A California startup, Nanostim, has created a wireless pacemaker that is the first of its kind to be approved for sale in the European Union. The tiny device -- "about the size and shape of a AAA battery" -- is inserted via a catheter that's threaded through the femoral artery, and is attached directly to the heart muscle where it can provide electrical stimulation. Nanostim was recently acquired by St. Jude Medical, which will put the device through more trials before submitting it for US Food and Drug Administration approval.

What's the Big Idea?

Over 4 million people around the world wear pacemakers to help regulate their heart rhythms, and 700,000 receive new ones each year. The Nanostim pacemaker can be inserted, removed, and replaced much more easily and quickly than a traditional pacemaker, which requires surgically opening a patient's chest. Also, the wires used to connect traditional devices to the heart muscle can move or fracture over time. Faulty wires have prompted recalls of some St. Jude Medical models in the past.

Douglas Rushkoff – It’s not the technology’s fault

It's up to us humans to re-humanize our world. An economy that prioritizes growth and profits over humanity has led to digital platforms that "strip the topsoil" of human behavior, whole industries, and the planet, giving less and less back. And only we can save us.

Why 'upgrading' humanity is a transhumanist myth

Upload your mind? Here's a reality check on the Singularity.

Videos
  • Though computer engineers claim to know what human consciousness is, many neuroscientists say that we're nowhere close to understanding what it is, or its source.
  • Scientists are currently trying to upload human minds to silicon chips, or re-create consciousness with algorithms, but this may be hubristic because we still know so little about what it means to be human.
  • Is transhumanism a journey forward or an escape from reality?
