System for detecting catheter looping or knotting

A detection system for detecting a loop and/or a knot in a catheter, the detection system comprising:

• a first coil and a second coil in spaced positions on a catheter body of the catheter;
• a driver coupled by a wired communication link to the first coil, wherein the driver is configured to transmit a first signal to the first coil;
• a receiver coupled by a wired communication link to the second coil, wherein the receiver is configured to receive a second signal from the second coil, wherein the second signal comprises:
• an amplitude indicative of a proximity of the first coil and the second coil;
• and
• a polarity indicative of a relative orientation of the first coil and the second coil;
• and
• a signal analyzer coupled by a wired or wireless communication link to the receiver that is configured to receive the second signal from the receiver and determine whether there is a change in the second signal indicative of a formation of the loop and/or the knot in the catheter.
