Medical Devices 

TT Electronics' magnetics provide high reliability for power and communications in implantable or external medical devices.

Miniaturisation in ultra-fine wire winding makes it possible to produce smaller medical device technologies. This means significant benefits to design engineers such as:

  • Real Estate Savings
  • Enhanced Design Flexibility
  • Increased Precision

The use of ultra-fine wire also makes it possible to create smaller medical device navigation technologies, with benefits including:

  • Less Invasive and Implantable
  • Safer
  • Uniquely Able to Reach Otherwise Inaccessible Parts of The Body
  • Enhanced Sensing Capabilities
