Catheter interface device, method, and storage medium

A method performed by a catheter interface device connectable to an imaging catheter having an ultrasound transmitter and receiver or an optical transmitter and receiver, and an external display device for displaying an image based on a signal acquired from the ultrasound transmitter and receiver or the optical transmitter and receiver, the method comprising:

• supplying power from a battery to the imaging catheter;
• processing the signal acquired from the ultrasound transmitter and receiver or the optical transmitter and receiver before the signal is transmitted to the external display device;
• storing, in a memory, history data indicating battery power consumption for each of a plurality of medical procedures performed using the imaging catheter, and a battery level indicating remaining power of the battery;
• calculating a number of medical procedures that can be performed using the remaining power of the battery based on the history data and the battery level stored in the memory;
• and
• displaying the calculated number of medical procedures.

A non-transitory computer-readable storage medium storing a program that, when executed by a processor of a catheter interface device that is connectable to an imaging catheter having an ultrasound transmitter and receiver or an optical transmitter and receiver, and an external display device for displaying an image based on a signal acquired from the ultrasound transmitter and receiver or the optical transmitter and receiver, causes the processor to perform a method comprising:

• acquiring a battery level indicating remaining power of a battery that supplies power to the imaging catheter and a signal processing circuit of the catheter interface device, the signal processing circuit being configured to process the signal acquired from the ultrasound transmitter and receiver or the optical transmitter and receiver before the signal is transmitted to the external display device;
• accessing history data stored in a memory, the history data indicating battery power consumption for each of a plurality of medical procedures performed using the imaging catheter;
• calculating a number of medical procedures that can be performed using the remaining power of the battery based on the history data and the battery level;
• and
• displaying the calculated number of medical procedures.
