Claims17
An esophageal intubation assembly comprising:
- a catheter comprising:
- a body structure extending along a body structure length from a proximal body end to a distal body end;
- a passageway extending within the body structure and along at least a portion of the body structure length from a proximal passageway end to a distal passageway end;
- a proximal passageway opening passing through the body structure at a proximal passageway opening location for fluidly coupling the passageway with an ambient environment of the body structure at the proximal passageway opening location;
- and
- a distal passageway opening passing through the body structure at a distal passageway opening location for fluidly coupling the passageway with an ambient environment of the body structure at the distal passageway opening location, wherein the distal passageway opening location is distal of the proximal passageway opening location along the body structure length;
- and
- cardiac stimulation circuitry comprising:
- a first electrode coupled to the body structure at a first electrode location;
- a second electrode coupled to the body structure at a second electrode location;
- and
- a communicative coupler assembly that electrically couples the first electrode and the second electrode in parallel, wherein:
- the second electrode comprises an electrode opening passing through an exterior surface portion of the second electrode;
- and
- at least a portion of the electrode opening aligns with at least a portion of the distal passageway opening for passing fluid therebetween.

An esophageal intubation assembly for use with a pacing device that comprises a first pacing device connector and a second pacing device connector, the assembly comprising:
- a catheter comprising:
- a body structure extending along a body structure length from a proximal body end to a distal body end;
- a passageway extending within the body structure and along at least a portion of the body structure length from a proximal passageway end to a distal passageway end;
- a proximal passageway opening passing through the body structure at a proximal passageway opening location for fluidly coupling the passageway with an ambient environment of the body structure at the proximal passageway opening location;
- and
- a distal passageway opening passing through the body structure at a distal passageway opening location for fluidly coupling the passageway with an ambient environment of the body structure at the distal passageway opening location, wherein the distal passageway opening location is distal of the proximal passageway opening location along the body structure length;
- a safety device comprising:
- a first safety device connector configured to be removably coupled to the first pacing device connector;
- a second safety device connector configured to be removably coupled to the second pacing device connector;
- a third safety device connector;
- a fourth safety device connector;
- first safety circuitry electrically coupled between the first safety device connector and the third safety device connector;
- and
- second safety circuitry electrically coupled between the second safety device connector and the fourth safety device connector;
- and
- cardiac stimulation circuitry comprising:
- a first electrode coupled to the body structure;
- a first communicative coupler assembly electrically coupling the first electrode to a first coupler connector, wherein the first coupler connector is configured to be coupled to the third safety device connector;
- a second electrode;
- and
- a second communicative coupler assembly electrically coupling the second electrode to a second coupler connector, wherein:
- the second coupler connector is configured to be coupled to the fourth safety device connector;
- the first safety circuitry comprises a fuse configured to prevent a signal with an energy above a particular energy threshold from passing from the first safety device connector to the third safety device connector;
- and
- the second safety circuitry comprises a diode configured to prevent current from flowing from the second safety device connector to the fourth safety device connector.
