Abstract
A multi-lumen catheter that contains two or more independent coaxial sensing elements which can be used for measuring and recording temperature over a wide area at the insertion site. In addition, this catheter can be used for withdrawing blood at its distal port. When a microwave probe is inserted into the proximal lumen and positioned within the catheter, it allows for accurate placement of the microwave field within the area which is temperature monitored.
