A recently granted patent (Publication Number: US11771402B2) describes an intraluminal medical system that allows for communication with various intraluminal devices used to obtain data from within a patient's body lumen. The system includes an interface device with a housing, a processor, and an analog to digital converter (ADC) that digitizes the intraluminal data. The processor is capable of identifying the sensor type of the intraluminal device and configuring the ADC accordingly by selecting a sensor-specific reference voltage.

The system supports a variety of sensor types, including intravascular ultrasound (IVUS) sensors with different transducer center frequencies. It can also accommodate imaging sensors, ultrasound transducers, ultrasound transducer arrays, optical sensors, pressure sensors, and flow sensors. The interface device includes a signal conditioning circuit that conditions the intraluminal data obtained by the intraluminal device, and the ADC digitizes the conditioned data.

The processor is responsible for configuring the signal conditioning circuit based on the identified sensor type. This involves selecting a combination of amplifiers and band-pass filters suitable for the specific sensor type. To identify the sensor, the processor sends a sensing signal to the intraluminal device and measures the impedance of the device in response.

The system may include one or more of the different intraluminal devices, and the processor can control the sensor of the intraluminal device to obtain the intraluminal data based on the identified sensor type. The processor itself can be a central processing unit (CPU) or a field-programmable gate array (FPGA).

In addition to configuring the ADC, the processor can change other parameters associated with the ADC, including the sensor-specific reference voltage. The housing of the interface device is designed for handheld use, making it convenient for medical professionals to operate.

Overall, this patented intraluminal medical system offers a versatile and adaptable solution for obtaining and digitizing intraluminal data from various sensors. Its ability to configure the ADC and signal conditioning circuit based on the identified sensor type enhances the accuracy and efficiency of data acquisition within a patient's body lumen.
