More Details

WARNING This kit definitely contains dangerous things. The flexNT transponder has not been tested or certified by any regulatory agency for implantation or use inside the human body. Use of this device is strictly at your own risk.

The flexNT is one of our next generation, high performance, RFID and NFC compliant transponders. It is coated in USP Class VI, ISO 10993 tested biopolymer which gives it an extremely thin profile and flexible structure suitable for installation just about anywhere. The flexNT has the same chip as the xNT, however the flexNT offers many times the readability, range, and performance of the xNT. They are shipped in small sealed plastic tubes with chlorhexidine solution.

Professional installation notes

Installation of a flexNT device should always be done by a professional.

  • Do not install under any gripping surface (e.g. no palm side installations)
  • Do not install atop or parallel to any joints (flex devices are only “semi-flexible”)
Scalpel Procedure
  • Make a 9mm wide incision in skin
  • Lift & separate dermal layer using elevator tool
  • The subdermal “pocket” should be at least 30mm deep
  • Remove all tools from installation site
  • Slide flex device under skin with sterile gloves – no forceps or tools
  • Suture to close wound – do not pierce flex device while suturing
Needle Procedure
  • Incise skin using a 4g (5mm diameter) piercing needle, bevel side down
  • Carefully insert the needle to a depth of at least 25mm
  • Be sure to lift the skin ahead of the needle’s point as you insert it
  • Slide flex device under skin with sterile gloves – no forceps or tools
  • Achieve complete hemostasis before applying bandaging
  • Use re-enforced butterfly bandage or dermal strips to pull wound closed
  • Apply transparent film (tegaderm) dressing overtop the dermal strips
  • While hemostasis is maintained, do not remove bandaging for 7-10 days

Important things to know about the flexNT

– The biopolymer is ISO 10993 and USP Class IV tested and certified, however the final product has not been tested post-processing, meaning material changes during processing could render the final product unsafe in some way. Testing is planned for later, however beta testers have had the flexNT since April 2016 and report no issues. Dangerous Things founder and CEO Amal Graafstra underwent the first installation of a flexNT beta device on 03/02/2016 above the second metacarpal of the middle finger of his left hand. So far the installation has healed excellently and there are no signs of rejection or irritation at the installation site.

– There is no “preferred” location for installation of a flex device. Customers are free to install a flex into any area of the body their installation professional is comfortable with, as long as it is in the fascia layer between dermis and muscle tissue and not in an area of flexion or under a gripping surface. Even though we use images which suggest installation above the second metacarpal of one of the fingers, it is not an ideal location for such a device. Fingers are filled with tendons, nerve bundles, and very important things all packed into a very tight space. We urge you to think about easier locations like the back of the hand or in the arm/wrist.
