Stanford University researchers developed an innovative device that conveniently monitors blood vessel surgery.
The innovative sensor is a compact device that is biodegradable, battery-free, and wireless, which warns a patient's doctor if there is a blockage in the artery. The research work was published in the journal Nature on January 8, 2019.
Paige Fox, assistant professor of surgery and co-senior author of the paper, said: “Measurement of blood flow is critical in many medical specialties, so a wireless biodegradable sensor could impact multiple fields including vascular, transplant, reconstructive and cardiac surgery. As we attempt to care for patients throughout the Bay Area, Central Valley, California and beyond, this is a technology that will allow us to extend our care without requiring face-to-face visits or tests.”
The new sensor is capable to remotely checking a healing vessel, thus allowing opportunities to doctors for earlier interventions. The device takes the reading with the help of an antenna of the sensor, which is similar to the ID card scanner.
The team demonstrated the working of the device in an artificial setting where they pumped air through an artery-sized tube to mimic pulsing blood flow. Moreover, the researchers implanted the sensor in the artery of a rat. They concluded that the sensor worked perfectly and successfully reported blood flow to the wireless reader.
Levent Beker, postdoctoral scholar in the Bao lab and co-lead author of the paper, said: “It was a very exacting project and required many rounds of experiments and redesign. Using sensors to allow a patient to discover problems early on is becoming a trend for precision health.”
