Summary:A system includes an introducer and a measuring device. The introducer is usable to insert a catheter into a blood vessel of a patient. The introducer includes a hollow sheath to receive the catheter when inserting the catheter into the blood vessel. A first plurality of electrodes is provided on the sheath. The measuring device is coupled to the electrodes, and is configured to detect a bleed in the patient at a first zone along the sheath by determining an impedance between a first pair of the first plurality of electrodes, and to detect a bleed in the patient at a second zone along the sheath by determining an impedance between a second pair of the first plurality of electrodes.
