Catheters


Catheter Sub-assemblies

Used extensively in cardiac diagnostic and corrective procedures, a thermodilution catheter is inserted into a vein in the groin or neck and fed through the heart into the pulmonary artery. A tiny glass sealed NTC thermistor is located near the tip.

During normal heart function, electrical impulses contract the heart muscle squeezing the blood into the arteries. Arrhythmias result when interference from damaged tissue or nerves effectively "short circuit" these impulses. The damage can result from genetic defects, heart attacks or other diseases and large segments of the heart can be affected. This problem has historically been treated with Pacemakers.

Thermistor Assemblies TYPE E INSULATION AB6E8
Type AB6 thermistor assemblies consist of small Thermoprobes or Thermobeads which are welded to insulated extension leads. The Thermobeads or Thermoprobes are hermetically sealed in glass and have fine diameter (.0007" to .004") platinum alloy leads. The platinum leads are cut short and welded to insulated extension leads and the joints are covered in one of several insulation types depending upon the application or environment. The assembly is then ready for insertion into hypodermic needles, catheters or other small housings which require extended leads.
