Intended Use
The Radiant Medical Reprieve® Endovascular Temperature Therapy System is indicated for use in cardiac surgery patients to achieve and/or maintain normothermia during surgery and recovery/intensive care.
Device Description
The Reprieve System consists of a single-use, heparin-coated, central venous catheter; a single-use, heat exchange cassette; an integrated temperature probe; and an external controller. The Controller unit has a user interface to select operating parameters and is connected to the Catheter via the Cassette and extension lines. The catheter is designed for placement in the inferior vena cava via the femoral vein using a 12 Fr hemostatic introducer sheath.
More Information

No
The summary describes a temperature therapy system with a controller and catheter, focusing on physical components and standard performance testing. There is no mention of AI, ML, image processing, or data sets typically associated with AI/ML development.

Yes.
The device's intended use is to "achieve and/or maintain normothermia during surgery and recovery/intensive care," which describes a therapeutic action.

No

The device is used for maintaining normothermia during surgery and recovery, which is a therapeutic function, not a diagnostic one.

No

The device description explicitly lists hardware components including a catheter, cassette, temperature probe, and external controller.

Based on the provided information, the Radiant Medical Reprieve® Endovascular Temperature Therapy System is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use is to achieve and/or maintain normothermia (normal body temperature) in cardiac surgery patients. This is a therapeutic intervention performed directly on the patient's body.
  • Device Description: The device involves a catheter inserted into the inferior vena cava, a heat exchange cassette, and an external controller. These components are used to directly modify the patient's body temperature.
  • Lack of In Vitro Activity: IVD devices are used to examine specimens (like blood, urine, or tissue) outside of the body to provide information about a person's health. The Reprieve System does not perform any such analysis of specimens.

The device is clearly designed for direct patient treatment and temperature management, which falls outside the scope of in vitro diagnostics.

Description of Device

The Reprieve System consists of a single-use, heparin-coated, central venous catheter; a single-use, heat exchange cassette; an integrated temperature probe; and an external controller. The Controller unit has a user interface to select operating parameters and is connected to the Catheter via the Cassette and extension lines. The catheter is designed for placement in the inferior vena cava via the femoral vein using a 12 Fr hemostatic introducer sheath.

Summary of Technological Characteristics

The Reprieve System uses established technology, materials, and construction techniques. The system employs standard heat conduction technology to warm or cool the blood using circulating warm or cool fluid in a closed loop system. The SetPoint System accomplishes this heat exchange through a catheter, located in the inferior vena cava, via the femoral vein, thereby adding heat to or removing heat from the blood by means of counter current heat exchange. The microprocessor based Controller circulates saline through the catheter and cassette and allows the saline temperature to be raised or lowered as it passes through a heat exchanger in thermal communication with a process fluid unit within the Controller. Patient temperature is constantly measured by the Controller using a temperature probe (K042388) integrated with the catheter.

Performance Test

The Reprieve Endovascular Temperature Therapy System has been tested for system performance. In addition the Catheter has been tested for functionality in accordance to BS EN ISO 10555, for biocompatibility in accordance to ISO 10993. and for sterility in accordance to ISO 11137. The controller has been tested for electrical safety in accordance to IEC 60601.

Conclusion

Based upon the successful completion of performance verification tests and the comparison to the predicate devices, the Radiant Medical Reprieve Endovascular Temperature Therapy System performs with safety and effectiveness equivalent to the predicate device.
