Abstract:
1. An introducer, comprising: a sheath for introducing a catheter into a blood vessel at an insertion site; a plurality of electrodes on the sheath; and an impedance assessment unit provided on said sheath and connected to said electrodes, said impedance assessment unit includes a power source, a wireless transceiver and is configured to inject one of a known current or known voltage across a first pair of the electrodes and measures the other of the current or voltage across a second pair of electrodes; wherein the impedance assessment unit is configured to compute an impedance based on the current and voltage and detect a bleed at the insertion site based on the computed impedance; wherein the impedance assessment unit is configured to transmit a value indicative of the bleed through the wireless transceiver to an external apparatus.
