Cryoablation devices are medical devices used in cryoablation procedures, which involve the use of extreme cold temperatures to destroy or ablate abnormal tissues, such as tumors.

These devices typically consist of a cryoprobe, which is a thin, needle-like instrument that is inserted into the target tissue.

The cryoprobe is then cooled to very low temperatures, often using gases like liquid nitrogen or argon, causing the tissue to freeze and eventually die.

Cryoablation procedures are commonly used in the treatment of various conditions, including certain types of cancer, abnormal heart rhythms (arrhythmias), and benign tumors. The use of cryoablation devices allows for minimally invasive treatments that can effectively target and eliminate diseased tissues while minimizing damage to surrounding healthy tissue.

In a cryoablation system, to prevent the cryoprobe (typically used for freezing tissues or areas) from solidifying or freezing to non-target areas during the process, it is common to heat the areas outside the probe.

In this process, the heating flow rate measurement is crucial.

Measure Heating Flow

To prevent the cryoprobe from accidentally freezing to unwanted tissues or areas, the system needs to timely and accurately control the temperature of the heating areas. The ultrasonic flow sensor / flow meter measures the changes in flow rate, helping the system automatically adjust the required heating flow rate to ensure that non-probe areas remain warm, preventing freezing of tissues outside the probe.

Responding to Control System Commands

Provide relevant data feedback to the control system. When the device control system detects abnormal or unexpected changes in the flow, it can take immediate action, such as adjusting the heating flow rate or triggering an alarm.

There are many benefits of integrating XY-TEK CG series ultrasonic flow sensor / flow meter technology into the medical cryoablation devices.

1. High Flow Rate Measurement Accuracy

The CG Series ultrasonic flow sensor / flow meter boasts a high accuracy of ±3% and minimal error rates, helping to minimize the risk of damage to surrounding healthy tissues.

2. No-invasive Measurement, Enhanced Patient Safety

By eliminating the necessity for direct contact with the fluid, the CG series clamp-on ultrasonic flow sensor / flow meters reduces the risk of contamination, streamlining the setup and operation of the cryoablation device.

3. Low Flow Rate Measurable

CG series clamp-on ultrasonic flow sensors / flow meters  can measure flow rates at 10ml/min, it can detect small flow rate changes in flow. This is particularly beneficial in cryoablation systems where small flow variations can have a significant impact on the patient treatment process.

4. Clamp-on Design for Seamless Integration

Designed for effortless integration into existing cryoablation devices, the Clamp-On Ultrasonic Flow Sensor / Flow Meters can help minimize downtime and operational disruptions.

5. Flow sensor OEM and Customization

XY-TEK ultrasonic flow sensor / flow meter team can tailor designs to meet cryoablation system-specific requirements, including alterations in sensor size, shape, color, output, and more.
