  • Microtubing with integral thermocouple
    Patent number: 6323413
    Abstract: A novel microtubing and a method of manufacture is provided. The resulting microtubing has at least two thermoelements separated by a resin layer except in defined areas where the insulating resin layer is selectively removed. The resulting microtube provides improved performance, reduced size, increased flexibility, and can be efficiently manufactured.

  • Manufacture of variable stiffness microtubing
    Patent number: 6314856
    Abstract: A process for manufacturing novel composite microtubing with variable stiffness over the length of the tubing. By varying the pick count of a braided layer the stiffness of the microtubing may be varied by a factor of 100 from proximal end to distal end. The continuous process allows a predetermined stiffness pattern to be repeated over a measured length for economical manufacture and results, if desired, in tubing of extremely small diameter and extremely thin tube walls.
