Abstract
A self-monitoring catheter system may detect an obstruction during use of a catheter. The system may include a catheter with an interior lumen that has one or more ports into the lumen; a first and a second electrode; and an impedance measurement instrument that measures changes in the impedance between the first and the second electrodes after the first electrode is exposed to fluid within the catheter lumen, thereby signaling an obstruction during use of the catheter.
