Terumo had four patents in internet of things during Q1 2024. Terumo Corp has developed a stent delivery system that can gather biological or stent-related information using a sensor while the stent is inside a living body. The system includes a sheath, stent extrusion member, and a sensor device with a sensor unit and pressing portion. The sensor device can be removed from the body by withdrawing the stent delivery system or the sensor device itself.

Application: Stent delivery system and stent sensor device (Patent ID: US20240023896A1)
The patent filed by Terumo Corp describes a stent delivery system that incorporates a sensor device to obtain biological-related information or stent state information from a stent after it has been implanted in a living body. The sensor device includes a sensor unit and a pressing portion to bring the sensor unit into contact with the inner surface of the stent. The system allows for the sensor unit to be moved within the stent and then removed from the living body by withdrawing the sensor device. Additionally, the patent includes claims for variations in the design of the sensor device, such as having multiple sensor units for detecting at different positions in the stent, using wire-shaped or coil-shaped pressing portions, and integrating strain sensors with the pressing portion.
Furthermore, the patent claims cover the use of different types of sensors, such as pressure sensors, blood velocity sensors, and strain sensors, to gather information about blood flow or stent condition. The system also includes an arithmetic processing device to analyze the signals from the sensor unit and calculate the biological-related information or stent state information. The combination of the stent sensor device and stent allows for the sensor device to be removed from the living body while the stent remains implanted. The method described in the patent involves inserting the stent with the sensor into the living body, expanding the stent, moving the sensors within the stent to gather information, using the sensor signal to determine relevant data, and finally removing the sensor from the living body while leaving the stent in place.
