A introducer is disclosed that includes an introducer sheath for introducing a catheter into a blood vessel at an insertion point, a plurality of electrodes on the introducer sheath, a flush line coupled to the introducer sheath including a proximal end and a distal end. In addition, the introducer includes an impedance assessment unit coupled to the flush line between the proximal end and the distal end and electrically coupled to the electrodes. The impedance assessment unit is configured to inject a predetermined current or voltage into a first of the plurality of electrodes and measure a resulting voltage or current, respectively, from a second of the plurality of electrodes.

Introducer sheath with electrodes

An introducer includes a sheath for introducing a catheter into a blood vessel at an insertion site and a plurality of electrodes on the sheath. The introducer also includes an impedance assessment unit connected to the electrodes. The impedance assessment unit includes a power source and a wireless transceiver and is configured to inject one of a predetermined current or voltage across a first pair of electrodes and to measure the other of the current or voltage across a second pair of electrodes. The impedance assessment unit also is configured to perform at least one: wirelessly transmit current and voltage values to an external apparatus for detection of a bleed, and compute an impedance based on the current and voltage and wirelessly transmit the computed impedance to the external apparatus for detection of the bleed.

Introducer sheath with electrodes for use in bleed detection

An introducer comprise a sheath for introducing a catheter into a blood vessel, a plurality of electrodes on the sheath, and an impedance assessment unit provided on the sheath and connected to the electrodes. The impedance assessment unit fixes one of a current or voltage across a first pair of the electrodes and measures the other of the current or voltage across a second pair of electrodes.
