1. A system, comprising:
an intravascular catheter or guidewire configured to obtain biological data while positioned within a blood vessel of a patient, wherein the intravascular catheter or guidewire comprises a proximal portion and a distal portion;
a first cable comprising an first flexible elongate body terminating in a first distal connector at a distal end of the first flexible elongate body and a first proximal connector at a proximal end of the first flexible elongate body; and
a second cable comprising a second flexible elongate body terminating in a second distal connector at a distal end of the second flexible elongate body and a second proximal connector at a proximal end of the second flexible elongate body,
wherein the proximal portion of the intravascular catheter or guidewire is configured to be coupled to the second distal connector,
wherein the first proximal connector is configured to be coupled to a hemodynamic monitoring system,
wherein the first cable is configured to be coupled to the second cable such that the hemodynamic monitoring system is in communication with the intravascular catheter or guidewire via the first cable and the second cable, and
wherein the first distal connector comprises:
an analog-to-digital converter (ADC) configured to receive the biological data via the second cable and convert the biological data into digital signals;
a microprocessor coupled to an output of the ADC and configured to:
process the digital signals into a format that is readable by the hemodynamic monitoring system; and
output the processed digital signals to the hemodynamic monitoring system via the first proximal connector;
a receptacle configured to receive the second proximal connector such that the first cable is coupled to the second cable; and
a housing, wherein the ADC, the microprocessor, and the receptacle are positioned within the housing,
wherein only the first cable and the second cable are disposed between the hemodynamic monitoring system and the intravascular catheter or guidewire such that the receptacle of the first distal connector receiving the second proximal connector is the only one removable connection disposed between the first proximal connector and the second distal connector.
